Tronsmart 54W 5-Port Desktop Charger (QC2.0) Review

Tronsmart reached out to me a week back and asked me if I would like to review one of their new products and share my opinion with them. I liked the fact that they didn’t specifically ask me to write good things about the product or highlight only its pros, which many companies do when they offer you a free review product. I decided to do a detailed review of this product and give my honest opinion.
Two days later, I received this Qualcomm Quick Charge 2.0 Certified Tronsmart 54W 5-Port desktop charger (I know! That sounds great). It’s been 4 days since I’m constantly using this with my 5 different devices that need USB charging. Two of my cellphones (S6 Edge+ & Nexus 4), a ZenWatch, a BlueBuds X and a BlueSYNC Bluetooth Speaker (another review product).
Before I start with the review, let’s look at the product page here and see what really does this product claim to do ?
Here’s the list of features mentioned on their website:-
1. Qualcomm Quick Charge 2.0 technology in one of the ports (distinguished by blue color)
2. VoltIQ – Smart Circuit to identify the power level required for charging each connected device
3. Backward Compatibility – Charge older smartphones which didn’t have high amp charging adapters
4. 54 Watts max output through 5-ports (not each)
5. Ultra Compact
6. Safety Guarantee – No Overcharging, No Overheating and Over Current protection
7. 18-Months worry free warranty
List of items received in the package:-
- The desktop charger
- A Power Cord
- 6 Feet USB Cable
- A Cable tie
- User Manual
Since we have set the base, let’s start the review..
It came in a nice and sleek cardboard package (probably recyclable), the content didn’t seem like shaking at all. The whole package was sealed with a plastic wrapper (which kind of makes the idea of recyclable box dumb). A paper seal would have made more sense here.
Here’s an overlook of the box (I’ve taken out the plastic wrapper already):-

}
Moving on, here are the contents of the box:-
Let’s be frank here. Nobody would actually trust their $900 brand new phone with a third party charger even if it’s a brand like Tronsmart. So, before I connecting this to my Galaxy S6 Edge+ and to make this review really worthwhile, I used this USB Current/Voltage Tester to check the power output of the product and compare it with my original charger. Usually less volt/amp wouldn’t harm your device but a higher power output may have an adverse effect if the device is unable to handle such high power. Even though I was pretty sure a product from brand like Tronsmart wouldn’t do such a thing, but better be safe than sorry… This tester is connected as an interface between the device (S6 Edge+) and the charger and displays power drawn by the connected device.
I connected the tester with my Edge+ and the genuine Samsung Adaptive Fast Charging Adapter. [Adaptive Fast Charging is almost equivalent to Quick Charge 2.0, only major difference being, Adaptive Fast Charging supports 5V and 9V adapters while the Quick Charge also supports 12V along with 5V and 9V. So, there’s the reason for my worry]. So, when connected to the genuine Samsung adapter, S6Edge+ was drawing 1.59Amp at 9.13V.
Next, I connected the tester between the Tronsmart Quick Charge port (Blue colored) and S6Edge+ and Edge+ was drawing 1.62 Amp at 9.00 V. Being a third party adapter, I didn’t really expect such accurate results. I know there is a marginal difference in voltage, but this kind of difference doesn’t matter at all.
Here's the image comparison:-
Galaxy S6 Edge+ can distinguish between a fast charger and a regular charger, so when I connected the Edge+ to a Tronsmart regular port, this is how Samsung tells you that its not utilizing the fast charging:-
Since I’m assured now that my S6 Edge+ is perfectly safe and compatible with this Tronsmart Desktop Charger, I wanted to move on to older devices which draws 1 Amp equivalent current and see if the charger’s VoltIQ detects and delivers the right amount of power. So, I connected my Nexus 4 to an Asus 1 Amp charger and recorded the readings as below: 0.87 Amp at 5.17V.
With Tronsmart Charger connected to the nexus 4, it was pretty amazing to see the following result:-
I didn’t stop there. Ofcourse my trust level has increased significantly on this charger, however, I wanted to go further with devices which draws extremely low current like my Asus ZenWatch and Jaybird BlueBuds X. And again, I was pretty amazed with the results because these devices, specifically my BlueBud X, draws extremely low current, like 0.01A (connected to laptop) and VoltIQ was able to detect just the right amount of Volt and Current for my device. Here’s the result from the test on my ZenWatch, BlueBud X and BlueSYNC Speakers respectively:-
I also verified that the readings are consistent even when all 5 devices are connected simultaneously.
Once I was totally satisfied with the output range it gives, I also wanted to verify the time it takes (the blue port) to charge my S6 Edge+ from 3% to 100%, so I ran a separate test. And again, result isn’t very different from what an actual Samsung Adaptive Fast charger claims to do. Here is the breakup of the charging time of S6 Edge+ from 3% to 100% :-
By now I should have, but I didn’t stop here either. I connected 5 devices to all 5 ports and have been doing the same for last 4 days to test if the charger heats up and trust me, it doesn’t even a bit. It’s been performing well and it stays cool. And it cleaned up the mess I had with 5 different charges connected to an extension.
Overall, I’m extremely pleased with this charger’s performance and the build quality definitely looks nice with good finishing. It doesn’t look like cheap plastic item at all. And I’m sure there’s no point in telling this since nobody would probably carry this in their daily bags, but this thing is really small. Look at the image below comparing it with credit card sized gift card.
Finally, here’s my pros and cons list for this item:-
Pros:
1. Fast Charging with Qualcomm Quick Charge 2.0 Certification and compatibility with Samsung Adaptive Fast Charging
2. Smart enough to detect all my device power limits - VoltIQ (this is what makes it useful)
3. High Power output even in regular ports (helps charging high end smartphone devices faster which doesn’t support Qualcomm QC2.0 or Adaptive Fast Charging)
4. No heat
5. Very Compact
6. 18 Months Warranty (should be enough for the money you pay for this one)
Cons:-
1. No LED to show charger is turned ON (personal preference)
2. Only 1 USB Cable inside box
3. Power Cord could have been longer
I know the cons section isn’t really applicable to everyone; it’s just my personal preference. However, if anybody asks me, I would definitely suggest this product in a heartbeat. It’s very cheap too. I know there are more such brands like Anker or Aukey, but I haven’t reviewed them, I reviewed this one and I’m totally satisfied.
Here’s a video review I created earlier:-
https://www.youtube.com/watch?v=DR8W9ozZgAs
*Please note that the readings of the first day (when I made the video) and the day when I wrote the review aren't going to match accurately due to reasons like % of charging. However, the values are approximately same and the difference can easily ignored.

Will consider this for my next purchase. Thanks for the detailed review :good:

[Quick Review] Tronsmart 3-Port Wall Charger with QC 2.0

It's been some time since I've reviewed another Tronsmart product. I got this Tronsmart 3-Port Wall Charger as a review unit almost 3 weeks back and I didn't get enough time to write the review since then. On the brighter side, I'm using this for 3 weeks now, so I can probably be more precise while writing it now. So here it goes...
I'll be splitting it up in following 4 categories and talk about each of them one by one:-
- Packaging & Content
- Build Quality & Design
- Functionality
- Pros & Cons
Packaging & Content
Tronsmart has never dissapointed me in this category, so I do not have much to say here. It comes in one of those recyclable brown box with a printed cover wrapped around it.

}
On opening the box, you can expect the following items:-
- 3-port USB Wall Charger (TS-WC3PC)
- 1 x 6 ft USB Cable (20 AWG)
- User Manual
- VoltIQ Information Card
One thing to notice here is, even though it has 3-ports, it comes with only 1 USB Cable. So, if you're buying it, make sure you have that many spare cables to use it with.
Build Quality & Design
If you're one of those who can't withstand a product with bad finishing, you and I are no different. Luckily Tronsmart understands us and give its products the best quality in terms of material used and overall surface finishing. Here's a look:-
The quality is absolutely fantastic. What makes it even better is its folding type plug which also makes it easy to carry around. It has a green power LED. From the size perspective, it's very small, not OEM Charger small though, but tiny enough to hold it in your palm. Here's a comparison between a Samsung OEM Charger and the Tronsmart 3-Port Wall Charger:-
The in-box USB Cable is a 20 AWG (for high current flow), very durable 6 ft long cable which should do a descent job if the device is to be used while charging.
Functionality
The unit has 3 USB outputs out of which, only one port supports quick charge output at 12V/1.5A while the other two ports are powered at 5V/2.4A each with VoltIQ Technology.
While reviewing the unit, I connected 3 of my mobile phones simultanously to check it's output. First I connected the USB Amp meter to the Quick Charge output which is connected to my Galaxy S6 Edge+. The total power drawn was around 14.76W which is definitely an output we can expect from a fast charger.
Next, I connected the USB Amp meter to a regular port which is powering my Nexus 4. One of the reasons for using a Nexus 4 here is to validate how much current is drawn since Nexus 4 is pretty old device and as far as I've seen, it draws only upto 5V/1A even from its OEM Charger. Like we can see below, the total power drawn is just 5.05W which is almost equivalent to 5V/1A and this ensures me that the VoltIQ is not just a marketing gimmick. I also turned on the display of Galay S6 Edge+ to validate that it is utilizing the fast charging even with all 3 devices connected simultanously (See the Fast Charing in notification ?).
Now, everything was good till this moment except when I went pull back the charger from the socket after an hour, it was HOT. Not burning hot, but you'll definitely feel it when you touch it. Not that it affected any of my devices (none of the 3 devices heated up during charging). It's the same common problem with all the small multi-port quick charge adapters available (3rd party) on Amazon. I did contact Tronsmart regarding the same and they told me that since the adapter is so small, heat dissipation is slow and they assured me that their chargers have passed CE ,ROHS,FCC, PSE etc certifications of conformity and the temperature exhibited is within the safety standard range.
Pros & Cons
Pros:-
- 2 x High Power Output + 1 x Quick Charge Output
- Superb build quality
- Small size with retractable Plugs
- Long and durable USB Cable
Cons:-
- Heats up quickly
- Only 1 in-box USB Cable

[Review]CHOETECH USB Type C Charger & USB Type C - Type C Cable Review

Hello,
I got a great discount from <MODERATOR EDITED - SPAM LINK REMOVED> on a USB Type C charger & USB Type C - Type C cable bundle for an unbiased review.
I had to pay a few Euro though but that was ok for me since it is always good to have some spare chargers & cables, just in case the stock ones break
CHOETECH USB Type C Charger:
<MODERATOR EDITED - SPAM LINK REMOVED>
The charger is slighty bigger in comparison to the stock charger you get from Google when you buy a Nexus 6P device.
The build quality is nice, I didn´t see any sharp edges. The text markings are easy to read too.
This charger can deliver a max. power output of 18W at following values: 5V @ 3A, 9V @ 2A or 12V @ 1.5A

CHOETECH USB Type C - Type C Cable:
<MODERATOR EDITED - SPAM LINK REMOVED>
I got the 1m version of this cable. There is not much to say about it, it looks good and seems to be of a similar quality like the stock USB Type C - Type C cable you get from Google when you buy a Nexus 6P device.
Both plugs have a <MODERATOR EDITED - SPAM LINK REMOVED> text engraved into the plugs. The contacts seem to fit well, the diameter seems to be the same like the stock cable.
Pictures:
Tests:
I used the App Ampere for the tests in order to have a good guess, if the charger and the cable is a good replacement for the stock accessories.
I got similar values, even when I combined all pieces together. It seems that these items can deliver what CHOETECH mentions in the descriptions.
The phone is charged fast and the best readout I could get was about 2950mA which is pretty close to the 3000mA you would expect in theory.
The charger feels quite warm in comparison to the stock charger but I guess it´s still ok.
I´m happy with these items and I hope that these will last for a while.
Did you make similar experiences too ?

I can confirm this. Bought the charger and a 2m cable one month ago and I'm still very happy.

That´s great to hear. Any more opinions ?

I´m waiting for mine. This is really good replacement product..

Just thought I'd throw my 2 cents into the discussion.
I got these CHOETECH cables to review and I was quite impressed with them. In all honesty they performed identically to the cable that came with my 6p. I noticed that my phone wasn't charging as fast as it was advertised (with both stock and CHOETECH cables) and was a little confused by it. I'm a musician and travel alot and on a recent trip I charged up in my hotel room and it was as fast as advertised (0-100% in about 97 minutes). It was then that I realised the issue may be with the power at my house.
Anyhow, if you're in the market for some additional cables to add to your arsenal, these are a worthy addition!

I did the following combinations:
CHOETECH charger + CHOETECH cable: The peak current shown by Ampere was about 2950mA, this combination charges the phone as fast as the stock items.
CHOETECH charger + Stock cable: The peak current was also around 2950mA or slightly lower. This combination also worked well, I couldn´t see any differences.
Stock charger + CHOETECH cable: The peak current was also near 2950mA. The phone also charged fast.
Now there are a few things to consider:
1) Ampere or similar tools are not 100% precise and can only be used to get a good guess if everything works out fine.
2) Even the slightest mechanical variation of the cable can also increase the resistance of the cable and lower the output voltage and the current. This can be tricky with USB Type C but the tolerances are so small that you might never notice a decrease of performance around 1-2%.
3) The built in battery doesn´t have a 100% exact capacity of 3450mAh. It can also have a slight +- tolerance which will affect the time measured to charge it.
Most people won´t check the exact time needed anyway It doesn´t matter if your phone needs 1,5 hours to charge from 3% -> 100% or 1,49 hours

I bought the chotech charger and 2 cables pack. Its working fine, but the cables don't seem to seat very well within the type c fitting in the ac adapter. They wobble. The stock ac adapter and cable are very solid. Wonder if anyone else's like that. The wobbly fit doesn't fill me with complete assurance and confidence over time.

I have this charger. I'm happy with the purchase. Recommended.

Choetech
After doing a few weeks of testing with the latest Choetech Type-C to C *9.9ft(3M) cable and the Type-C 2.0 rapid travel charger, I think it's time I say a few words about them.
From my first impressions I was like wow this cable is super long. *Which could be a good or bad thing. I've been using stock cables for all my devices for a long time, and they have all been 3 to 4ft long. Which in today's world not long enough and not really logical if you need to have it behind a desk or while using it.
But anyways the cable is very nice and it actually snaps into my Nexus 6p. You can literally hang your *device from the cable without it falling to the ground. I tested the cable with CheckR app and it is approved and never had a issue charging my precious Nexus.
*Now for the charger not much I can say about it except that it just works. Charges my device from 5% to 100 in just over a hour. My Nexus says its charging rapidly on the lock screen. I have noticed sometimes when the charger is working really hard it makes a slight buzzing sound. But once the device gets to a certain percentage it stops. Now this isn't all the time just every so often. But it never effected charging. I highly recommend you all purchase these two products. You won't be dissatisfied.

Let this Google employee help you find a USB Type-C cable
I have bought 2 USB-C cables to USB 3-A & one did not click in to Nexus 5x & the other one says Slow charging?

Did you buy these Choetech versions of another brand, what charger brick are you using.

The buzzing sound while charging kinda worries me. anyone else? aside from that, and the heat it puts out it seems to work fine.

I talked to them last night. They have a new model that fixes that. Give them a email back if you purchased from Amazon. And if you buy a new one today you'll get the latest model from Choetech

The buzzing sound might be the result of saturation of the transformer built inside. I didn´t notice any buzzing since I didn´t put my ear next to the charger
A newer revision is always nice to have

It's pretty noticeable when you chilling with no TV on.

I checked my unit again and I can confirm a slight buzzing noise. It is barely audible though, you really have to put your ear next to the charger. I think this is something common with most chargers and as long as the device works, I would not care too much about it

[Review]iVoler USB Type C Power Bank 10000 mAh (5V @ 3A IN/OUT) Pix

Hello,
I got a free sample of this device from <MODERATOR EDITED - SPAM LINK REMOVED> for an honest and unbiased review.
Since I didn´t have any Power Bank for my devices, I was excited to try this one out
<MODERATOR EDITED - SPAM LINK REMOVED>
This Power Bank is quite small and easy to carry around. It provides enough juice to help you out through longer journeys
The build quality is nice, I didn´t see any sharp edges. The text markings are easy to read too. I don´t care too much about the looks of this device but I think that it doesn´t look cheap at all. In fact I really like the overall design.
What I really like about this Power Bank is the USB Type C Output which can provide a charging current of 3A @ 5V, like a regular USB Type C charger.
Features:
Optimized Charging/Discharging Efficiency: Up to 85% conversion rate for Type-C and up to 88% for USB.
TRUE TYPE-C FAST 3A INPUT & OUTPUT: The first ever external battery charger with USB-C/Type-C. Use it to quickly recharge the external battery, or to power the latest computers and smartphones and smart wearable devices with USB-C/Type-C ports.
DUAL USB PORT: One USB Type C Port that supports up to 5V 3A. Also included one USB-A Port with smart auto detect technology which charges up to 5V 2.4A maximum for other non Type C devices.
RAPID RECHARGE: Even with a huge 10000mAh battery, It only takes 3.5 hours with a compatible 5v 3A Type C Charger.
TYPE C Compatible devices: Google Nexus 6P/ 5X, Apple New Macbook (2015) 12 inches, Microsoft Lumia 950/950 XL, OnePlus 2, Google Chromebook Pixel.
WHAT YOU GET: iVoler TYPE C Power Bank, One USB-A to USB-C Charging Cable (with 56K ohm resistor which is compatible with any old USB Charger), One USB-C to C Charging Cable.

Tests:
I used the App Ampere for the tests in order to have a good guess, if this Power Bank can actually deliver what it promises.
I was able to charge my Nexus 6P with a current of about 3000mA (=3A) which is what you would expect from a regular Type C charger too.
It seems that this device can deliver what <MODERATOR EDITED - SPAM LINK REMOVED> mentions in the descriptions.
I also tried this Power Bank with my old Nexus 5 (2013) and a Fenix UC30 LED Flashlight and everything worked out fine.
My Power Bank uses blue LEDs instead of green LEDs.
I´m happy with this Power Bank. It is small enough to fit in every pocket and still has enough juice for my needs. It is able to replace a USB Type C charger in terms of charging speed which is awesome.
I will need a few more tests in order to check the efficiency but for now it seems that the values of 85% for USB Type C and 88% for USB seem to be realistic.
You should be able to fully charge a Nexus 6P about 2x with one full Power Bank. You can charge this Power Bank very fast too by using your USB Type C charger
Did you make similar experiences too ?

1. Update : No problems so far with the charging of devices. The power bank doesn't heat up while charging my devices.

2. Update: Still no problems with charging the phones. I will have a total % of Nexus 6P charges soon

Ok guys, I think I can present the test results
If you fully charge this Power Bank and ONLY use it to check the capacity from time to time ( short press on the power button, long press to shut this power bank off again ) and charge a Nexus 6P only, you can get about 190% of charge until this device will shut off and discharge completely. This value can be slightly higher or lower, depending on how much you fiddle around but let´s assume that 190% should be something everybody could obtain for now. Let´s ignore some measure errors and tolerances since this approximation should be realistic enough.
190% of Nexus 6P Battery = 6555mAh of usable capacity which is a very good value for this power bank.
It seems that the efficiency of this power bank is quite high if we look at it from this perspective.
Assuming that this device uses Battery Cells with these values: 10000mAh * 3,7V = 37Wh ---> 37Wh / 5V = 7,4Ah --> 7400mAh capacity which could be used in theory if we had a efficiency of 100% ( which ofc is not possible since these Battery Cells also feed the charging circuit which also has some losses too. ).
Now let´s have a look at the 190% of the Nexus 6P charge again: 1,9 * 3450mAh = 6555 mAh of usable capacity until the power bank is fully discharged and shuts off.
6555 mAh / 7400 mAh = 0,8859 --> 88,6% efficiency.
It seems that the USB Type C output is very good but you have to consider that my tests might not be 100% precise but good enough to check if this power bank really works the way it should. I think that it´s worth the spending and iVoler didn´t promise too much
In conclusion: This Power Bank can charge a Nexus 6P nearly 2x which is a good value. It is small enough to fit in every pocket and doesn´t weigh a lot which makes it a great companion

The only thing keeping me from buying this is the aesthetics... It's not that good looking imho. I have an anker astro e4 2nd gen and it charges the 6P really slowly, but the only anker alternative is a massive 20100mah battery
Inviato dal mio Nexus 6P utilizzando Tapatalk

Well, the looks of some gadgets might be important too but I´m not the guy who cares too much about them The looks of this Power Bank are ok in my eyes, not too fancy but also nothing I would consider as "ugly" or "cheap looking".
One thing to consider is that the capacity mentioned by the manufacturers is only the capacity of the built in Battery Cells; not the 100% capacity you will use for charging devices only since the charging circuit also needs some of the juice in order to work
Let´s assume that a cheap and random Power Bank might claim to have a capacity of 34500 mAh. One customer might think that this capacity divided through the capacity of the built in phone battery might equal the amount of charges ? In this case you could charge a Nexus 6P about 10x ?
Not this time The cells used have a voltage of 3,7V most the time.
One short approximation might be to have a look at the power first: 34500mA * 3,7V = 127,65W
This is the power you could achieve from the used Battery Cells. Now we need to consider that we don´t use a voltage of 3,7V for the USB ports but 5V instead which requires a circuit to transform the 3,7V up to 5V ( most the time through a step up converter circuit ).
127,65W / 5V = 25,53A which could be translated into 25530mAh if we can transform the power from the Battery Cells without any losses ( 100% efficiency which is impossible ).
Now let´s assume that one cheap and random Power Bank might work at a efficiency of 75%: 0,75 * 25530mAh = 19147,5mAh
Roughly you would get a usable capacity of 19147,5mAh: 19147,5mAh / 3450mAh = 5,55x
That´s the tricky part with most power banks. And I admit that it´s rather tough to find a smaller Power Bank which is not too big and still fits in a pocket while also being able to use a modern USB Type C output. Other Power Banks have a greater capacity but also cost more and are not very small.
I guess that not everybody is willing to carry a large Power Bank in his pants...if he even manages to fit such a brick inside These huge Power Banks are great for longer journeys though if you carry them in a backpack anyway.

[Review] Tronsmart Presto 12000mAh USB-C Fast Charging & QC3.0 Powerbank

Disclaimer: I was sent these items in exchange for an unbiased review.
Tronsmart Presto 12000mAh Powerbank
Unboxing and First look
Overview
I have been searching for a nice powerbank to charge my Nexus 6P since I bought it back in September of last year. Tronsmart finally made what everyone (in my opinion) has been looking for in a battery pack; this battery offers both QC 3.0 and Type-C fast charging due to the way it’s designed. I’ve tried a few different battery/power banks before this one for the Nexus, yet all of them that offer a Type-C port break the USB specification.
Tronsmart claims this powerbank is one of the most efficient on the market giving you the ability to maximize the power it stores to charge your phone. I haven’t tested that claim yet, but I fully intend to do so and publish my results below. I also own a 12000mAh Aukey powerbank, and a 10400mAh Choetech one as well. I do have other batteries, but their capacities aren’t similar enough to compare here.
What’s in the Box
-Tronsmart Presto 12000mAh Powerbank
-Documentation
-USB A-C charging cable with the proper 56k ohm resistor
Build & Design
In the typical Tronsmart style they have opted for a glossy plastic border alongside a matte plastic body. The plastic feels nice, and has a subtle texture on the matte section giving it a more refined feel. I appreciate how Tronsmart carried over their design language across multiple products (chargers, powerbanks etc.) which gives the end user a familiar feel to their products.
On the front of the powerbank you will find two ports; the first is your standard USB-A that offers QC 3.0, while the second only charges via USB-C fast charging. I like how they separated the circuits to offer both standards in one nicely designed battery especially for people like myself that own a Quick-Charge enabled phone (QC 1.0/2.0/3.0).
Along the side you will find a power button that turns on the battery for when you want to charge your phone(s).
Charging breakdown by port
Input (Type-C): DC:5V/3A
Output (Type-C Port): DC 5V 3.0A Max
Output (QC3.0): DC 5V-6.5V/3A 6.5V-9V/2A 9V-12V/1.5A
Summary
This has quickly become my new go to powerbank given the wide range of charging options it offers for both of my phones.
I also really appreciated the compact design, solid construction, and consistent styling offered.
I will follow up this review with a battery test to see how efficient it is while charging my Nexus 6P over USB-C and my S7 Edge via the USB-A QC 3.0 port. I’ll also add a short review of the braided USB A-C cable I was sent tomorrow.
Comparison: Tronsmart Presto vs Choetech, and Aukey Powerbanks
Tronsmart Braided USB A-C Cable
I own a ton (literally/physically) of USB A-C, C-C and MicroUSB cables given the number of phones I have. I first wanted to say how I’m impressed with the quality of this particular cable because it’s built well. I also own the I-Orange USB A-C, and C-C cables, but those are more expensive even though they are also high quality. The Tronsmart one features a nice braided nylon sleeve giving it more durability in the long run couple with nice aluminum housings for each end. The cable offers data transfer at USB 2.0 speeds (480mbs) which is perfect for the Nexus 5X/6P, or any device that doesn’t support USB 3.1 over Type-C. I have no complaints about the cable, and given how it meets the USB spec with the proper 56k ohm-m resistor you shouldn’t run into any issues.

Looks great! The main thing I'd like to know is how fast the 6P charges through the usb-c port in comparison to my oem usb-c cable & brick. So far I haven't seen a power bank that actually charges quickly through the usb-c port and this looks promising!

Is this available to buy yet:?

Sounds great... What's the dimensions and weight? Nm, here it is:
Product Dimensions 7.5 x 3.5 x 1.2 inches
Item Weight 10.7 ounces

you guys sure don't like to use google.

I just ordered mine, will be arriving tomorrow.

I'm going to post some more updates to the OP this afternoon. It is available for purchase on Amazon, and other places from what I've seen, but XDA doesn't like when you post product links in the OP.

Disappointing that this is bigger than Anker's while having only 60% of the capacity.

Here's something i don't understand. Back in November, when you reviewed the 20100mah ravpower, you said

Clearly shows QC3 charging due to the higher current, nearing 3A there. So this included-in-the-box a-c can handle more than 1.5A. Why ?
Does not indicate that 3A is reaching the 6P.
can you post a photo which indicates that close to 3A does reach the 6P.
with earlier banks there was always this doubt whether they were putting out close to 3A or 2.4A.

Went digging around for better photos that showed the specs clear and found one.
Note that it allows to charge devices ie. output using QC3 going up to 12V but will only accept 5v3A on the input. Why ?
No phone is going to require 12V on the input but a charger will certainly benefit from 12V QC3 as you can push over 20W with a suitable charger to charge it instead of 14W. Net result is your wait time to full charge of the power bank reduces by 50%.

Will this show Charging Rapidly when I plug my phone in this? Also, can I use the wall charger and C-C cable my phone came with for charging this power bank? Thanks!

I've just got mine from Amazon and can confirm that it displays CHARGING RAPIDLY. This is only displayed by using the C to C cable which is the one that came with the phone. Hope that answers your question.

I just posted a similar review of the product over on the G5 forums:
http://forum.xda-developers.com/lg-g5/accessories/tronsmart-presto-12000mah-qc3-0-usb-c-t3415369
This is more from the QC3.0 side of things as I do not have a Nexus, so it may not be as relevant to those on this thread.
One difference I believe I'm seeing between our reviews is that in charging my battery pack, it never went above 2.4/5V. It was measured using basically the same technique (USB-A multimeter plugged into a QC3 adapter, connected into a USB-A to USB-C cable, into the USB-C port of the battery). Maybe I'll try a different QC3 AC adapter.

I picked up this powerbank a couple days ago and ran a simple test to compare the charging speeds between the tronsmart powerbank and my wall charger. Both times, I ran the phone's battery down until it powered itself off before starting the test. Here are the results
Through Wall Charger (with 3rd party USB-C to C cable)
@ 15 min - 22%
@ 30 min - 42%
@ 1 hr - 80%
@ 1 hr 15 min - 91%
@ 1 hr 35 min - 100%
Through Tronsmart Powerbank (with 3rd party USB-C to C cable)
@ 15 min - 17%
@ 30 min - 38%
@ 1 hr - 76%
@ 1 hr 15 min - 90%
@ 1 hr 40 min - 100%
So far, pretty happy with the charging speed.

The USB-C port is only rated for 5V/3A, while the USB-A port is a QC 3.0 port. This is why it will quick charge my S7 Edge over the USB-A port since its using micro USB. I can post more about it when I get home from work tonight.

Didn't get a chance to post what I wanted last night because I got home late from work. I will try to do it today assuming all goes well. For those of you that are curious I managed 2.1 charges using C-C fast charging out of the battery pack resulting in a ~61% battery pack efficiency

just got this and i was not able to get charging rapidly msg on my nexus 6p when using supplied cable or my own a-c cable i purchased from google.
able to get quickcharging with a-c cable on my gf samsung galaxy s6
have not tried the c-c port charging on nexus 6p. will report back with results.

The USB-A port is a Qualcomm Quick Charge port, not a USB-PD port, so you won't get quick charging on the 6P from it.
You need the C-C cable to get quick charging on the Nexus.

Just ordered mine based on this review

I went back and used a different QC3.0 AC charger to charge this battery. This time, it was a nice Tronsmart branded one. The numbers were far better, ~15Ws, about 2.5-2.6A and 5.7V. So the charger you use to juice up the Presto will make a difference in charging times. This confirms the numbers @Pilz was getting.

I am looking for a fast battery charger for Nexus 6p, reading through this thread am I right in assuming then the only way to get a charge above 1.5ish amps is to use a USB C to C connection for the Nexus 6p when charging.
