So my DHD arrives tomorrow.
After reading about battery life, I want access to as many chargers as possible.
Can you tell me: Will my existing Micro-USB Chargers (Blackberry) be compatible with the DHD? I'm not sure if each unit will require a specific voltage / wattage?
Or can I just plug & play with which ever Micro-USB charger I come across?
Thank you & sorry if it's a dumb question...
Any cable will do fine. Definitely if you're charging through a PC since I've never heard of a phone/battery that can't handle the 5V it outputs (max for USB charging). A mains charger you can never be too sure with since it may have higher current/watt output, but I've really never let this stop me except that I'd avoid using cheap Chinese knockoffs.
It depends... microUSB connected to computer will be of course good, as it is hardware limited to 0,5A. External chargers are good question, but in my experience the phone/battery usually have a charge limiter so even if the charger does allow you to use higher current, the phone doesn't have to use all the power it can get.
For example i used the Nokia AC-10E charger for my Motorola Milestone since i bough the phone, and had no problems with it. And will use it for DHD too.
The official HTC chargers have an outpur of 5V/1A, so as long as your charger has the same output you should be good.
Nokia AC-10E has 1.2A, but as i said - that is the maximum it can give to the phone, batteries/phones have a current regulators so even if you connect a charger which can give you 2A @ 5V, nothing will happen - the phone will regulate the current which is used to charge the battery.
Hello everybody,
I have a problematic that I will explain you :
I'm working in a company which rents cell-phones (only Samsung Galaxy S, it's why I post in this part of the forum), with a software installed on these.
But the problem is that we have a lot of SGS, and not a lot of outlets, so when we need to recharge a huge part of these phones it's a mess.
We want to find a charger with at least 4 USB ports, like this :
Kensington 4 Port USB Charger, you can find features on amazon (I can't post external links, because I'm new on the forum)
or
Lenmar ACUSB4 Adapter Powered (Also on amazon)
Or more, like this :
Plugable 10 USB Port Power Adapter (still amazon)
or
Plugable 7 Port High Speed USB 2.0 Hub with 3A Power Adapter
But I have another problem :
I need to have a charger which supplies more than 500mA per port/device, because it will take too much time for charging, and if a customer want to rent a phone quickly, I also have to charge it quickly.
I found this :
Cambrionix c3-Case (features on the Cambrionix's website)
but I'm sure it will be very expensive and I don't have the features so I don't know if I can charge 16 SGS, with a least 1 Amp per port.
We tried to charge the SGS with a Nokia charger with 1.2 Amp, and it was much faster than with the OEM charger from Samsung. But it's impossible to find a hub charger with 1.2 Amp port, because an USB cable can just support 1 Amp.
So I want to mix those 2 ideas :
1) to use the maximum capacity of an USB cable (1 Amp) but for each port and for each device
2) to charge, at least 4 devices in the same time (but 8 or 10 will be better)
Do you understand my problem, and can you give me some ideas or names of products if you know some.
Thank you
why dont you use a high power usb hub?
why dont you buy reserve batteries? you can get them cheap and external chargers too.
Buy original batteries and external chargers, easiest and fastest way to do this than to a rely on a 1A charger.

I thought about high power usb hub, but the problem is that generally this kind of hub, because they are plugged on a computer, can't give more than 500 mA per port/device.
We don't want to buy reserve batteries, because with the number of SGS we have, it will be a mess. I mean if we have 100 reserve batteries we will never know if one battery is charged or not...
An external charger means that we need to give that with the phone to the renter and we don't want to burden our customers with another device.
I'm thinking about another solution :
Maybe I can buy a powered USB 3.0 hub, because USB 3.0 can provide 900mA per port.
But I'm not an electronic engineer and I have a question :
I found powered USB 3.0 hub with 7 ports, it's written that each port can provide 900mA, so for this it's ok. But it's also written that the Power Adapter is 5V/2A.
So i'm wondering if I plug 7 devices, do they will share 2A together (so it's mean each port will provide 2A / 7 devices = 300mA per device) or there is no relation between the amperage of the power adapter and the amperage that ports can supply, so they will effectively provide 900mA each ?
of couse every port can provide 900mA but not all at the same time. they share the 2A. maybe there is some more current from the pc if its connected (+500mA ?)
fact is: if there are 7 devices connectedyou will never have 900mA at every device. i guess max 500mA at 7 devices.
At the end of the day the phone only needs a basic 5 Volt supply and it'll charge.
Why not just buy some USB sockets from RS check out the wiring diagrams for USB and the buy a 5 Volts high current PSU from Ebay.
Something like this:

Would take about an hour to construct wit the right tools.
Hoe this helps
Logicalstep
why won't you just buy a lot of extension chords? i mean those SGS's should have a bundled charger, right?
Our customers can rent the smartphone directly from us, but also in some partners places, which are luxury brands, so we can not give to this luxury company something built by us, they will say no.
We need an official product, not something which looks like cheap...
And our partners don't want to use 7 or 8 outlets to charge phones, they want to charge all in the same place and easily, so the hub is the best solution, or something with the same idea.
I didn't get the idea with extension cables ?
I think your only option is to use spare batteries and chargers.
It would be fairly easy to create a nice looking charger box.
You could mount the chargers to the top of a thin box, then have their power cables go inside the box and all connect to one power socket out the back. Nice and neat and does what you need.
If you are looking for an off the shelf solution, then Google is your friend, but I don't think you'll find something that does what you need.
How much is you company willing to pay...I'd be interested in building it for you, but it would have to be worth while.
I get the feeling that you were after a cheap quick fix for this, which I don;t think exists?

It could be interesting but my company is in Hong Kong, so I don't know where you live but if you live far away from Hong Kong the shipping cost will be very expensive, maybe more than the cost of the product.
My moto g (1st gen) is about to arrive but I don't know how to charge it yet. I heard it takes long to charge in PC and I need a wall adapter for charging on the go anyways. Original brand ones are really expensive and I want to avoid that cost if possible. So is it safe to use a generic (most likely without any brand) wall adapter? For example one that says 100-240VAC, 50-60 Hz Output 5.0VDC 1.2mah. If not, what should I take into account when looking for a charger?
Thanks in advance.
It's not necessary to use original moto charger but it's recommended you can use any other chargers for charging With appropriate Voltage values...
Sent from my XT1033
All USB chargers have a regulated output voltage of 5 volts DC, and all of them are compatible with any device that charges via a USB/mini/micro port.
The difference is the maximum charging current, which generally ranges from a low of 300 milliamps to a high of 2 amps. More current will fill up the battery faster, as long as the charging control circuit on the device will accept more power. Regular USB ports like the ones on your computer are specified to put out a maximum of 500 milliamps current, so most device charging circuits will detect when they are on a computer USB port and limit their current drain to 500 milliamps to avoid triggering a "port overload" shutdown on the computer.
Devices with big batteries (like tablets) will take a long time to charge with a low-capacity charger, so you generally want to use a higher-capacity 2 amp charger with those to cut the charging time. Phones are generally somewhere in the middle - they'll charge in a reasonable time with a 1 amp charger, but they might benefit from using a 2 amp charger. You can still charge them using a low-capacity charger or a computer USB port, but you may need to shut the device off while charging if it consumes more battery power in normal operation than the charger can pump into it. And it might take a very long time (like 24 hours) to charge a big battery from a small charger.

Yes I'm aware of all this. The thing is I purchased it from Amazon and it doesn't come with a charger. That's why I need to purchase one. I know it works without problems with samsung, htc, blackberry, etc chargers but I don't know if it works -without problems and risks- with a generic charger. By generic I mean those chinese cheap ones that "imitate" original ones. So are those safe? Thanks again.
There's generally no problem with an inexpensive generic charger, but cheap junk is cheap junk. If it costs $1.99, and the connections are poorly soldered, the components are under-specified, and the construction quality is generally shoddy, then sure it can easily break, overheat, or go up in smoke. It could even conceivably damage your connected device. Just use some common sense in evaluating when something is too cheap.
I just got a samsung charger which seems to be for the note 2.. My worry is that I'm not entirely sure if it's original (even though build quality seems good) or not because of many reasons: a) I just noticed the model on the box (eta0u10ebecstd) is different than what is printed on the charger (eta-u90ewe) , including amperage listed (0.7a on box, 2a on charger) even though the box had the security seal b) I google'd about the model in the charger and I only saw it with the european plug presentation, didn't see a single american plug of that model (and I have the american plug). c) there seems to be 2 "presentations" with different printings (what varies is the location of the certification logos mainly and 1 extra certification for each "model" the other one doesn't have)
So my question is simple: Let's suppose the charger is not original, can it damage my phone? Thanks again.

If it is not Genuine avoide using as much as you can.
Using a genuine Samsung with Motorola or any charger made by real maunfacturer (Nokia, Samsung, LG, HTC.... etc) with any other phone is ok
but a duplicate charger is always a risk, because you never know what has been compromised.
Alright, I'll get a genuine one asap. Any tips to differentiate between an oem or duplicate charger?
"Genuine" is not a word that applies to USB chargers. Perhaps you mean "same brand as my phone", or "recognized brand name". That's one way to be sure you're getting acceptable quality. But you'll save some money if you just use common sense in evaluating the price and quality of what you're buying. There's nothing wrong with most generic USB chargers, and there's certainly no problem using a different brand-name USB charger with your phone.

There are ways to differentiate then, but you need to measure the output under load and see if there is noise and ripple with an oscilloscope, which is not in everyone's possibilities.
Best way to get a genuine charger for cheap is to buy it from a friend who has it from some old phone. Or just look for brands like Nokia, Sony, Hama, Belkin, Energizer etc in some trusted sellers like Amazon or big local hypermarket.

Ok so I found 3 chargers on Amazon that seem to have good reviews but I don't know much about brands so I hope you can help me to choose (can't post links). Which brand is more reputable in chargers? New trent, anker or powergen? Thanks

Powergen afaik are making high-power output chargers.You'd be fine with one of theirs, their quality is airtight and the prices are good.
I have many chargers, but this one seems to be a winner for multiple ports with the added quick charge 2.0 port.
http://www.amazon.com/Qualcomm-Cert...mer-Included/dp/B00ZF7XLJU/ref=cm_rdp_product
I've had some more time reviewing this charger since I use it on a daily basis in my car. My original review is still true and can be found below. I've added a couple images of the product to show the quality of the finish as well as a size comparison between a couple other multi-port chargers I have. While this charger is the largest of my stash, it also provides the most charging ports while incorporating a quick charge 2.0 outlet. The size is a double edged sword in my opinion. Many 12v outlets are recessed, so the longer adapter of the Tronsmart charger can be quite beneficial. I know it would help in my Toyota Camry, but not so important in my Honda Odyssey. Due to the longer adapter size, I'm concerned I will one day drop something on it and damage my 12v outlet.
Anyways, on to the review.
Pros:
+4 USB charging ports (1 QuickCharge 2.0 + 3 auto detect 2.4Amp)
+Slim simple design
+No bright annoying LED
Cons:
-none to report (possibly the size)
The Tronsmart 4 port car charger is simply amazing. I have tested it thoroughly over the past week and have decided to use it as my primary car charger! I own many many car chargers, but there are very few that provide 4 powerful charging ports in such a compact design. This charger is rated at 54 watts, but all you really need to know is that it will charge all of your devices with ease. The primary advantage this car charger offers is the 4 port design with 1 being Qualcomm Quick Charger 2.0 certified. This means it is designed for long term use as new phones and products are just now being developed to work with this technology. The remaining 3 ports are not to be forgotten either, rated at 2.4 Amps each. They are also smart charging ports (Tronsmart calls them Volt IQ ports) which basically means the port will automatically sense and charge the connected device at its maximum rate.
I tested this charger using a variety of devices (Samsung Galaxy S6, S5, iPad, iPhone 6, and battery banks) and they all accepted the charge immediately and at similar charging currents as I've seen on with other chargers. My Galaxy S6 registers this charger as fast charging when connected to the Quick Charger 2.0 (blue) port. I used a Portapow V2 USB current meter to verify the charging rates while all four ports were in use. I alternated devices between the ports and the results are consistent with advertised rates. Through my experience testing many chargers, I've come to learn that the charging limitation comes down to either the charger, the USB cable, or the device itself. Rest assured that this car charger is not the limiting factor when you are maximizing your charging speeds.
I received this product at no charge in exchange for an honest review. I am using this charger on a daily basis as my primary charger, so I will update if I notice anything out of the ordinary. Please also let me know if you have any specific questions and I will do my best to answer them.
I agree. I also received this charger from Tronsmart, and it's been great!.
(Mine was sent for free, in exchange for my writing an honest review. [http://www.amazon.com/review/R9A6YSQ37WQZE] And, if I didn't like it, I wouldn't hesitate to say so. After all, it's a $20.00 item. Definitely not worth being a shill for that. Fortunately, I like it very much.)
The charger seems to be one of a number of quality items being manufactured in China, and repackaged under the Tronsmart, Anker, and Aukey brand. (Most of those items were purchased, including others from Tronsmart). But, this isn't a bad thing, as I've used many accessories from each over the past couple of years, and they've delivered good performance at a good price.
My setup is a Nexus 6, while my wife uses (my old) Nexus 5. We both drive Honda CR-Vs. My N6 charges quickly using the Qualcomm QC 2.0 port, although it also charges well with the Volt IQ "intelligent" ports as well. My wife's N5 charges quickly, too, albeit without the QC 2.0.
What I like about this charger is that it's still relatively small, despite having the 4 ports. This is VERY HANDY when my kids are in the car for a long drive, and their own tablets are sucking down battery life. When used with a longer USB cable from Tronsmart (or, Anker, which I've also purchased), they can charge from the back seat.
I bought a single-port Tronsmart QC 2.0 car charger, as well as a two-port Aukey (one port QC 2.0, one a "smart" charging port), and though they all work well, this is the one I have stuck with. Dependable, good quality, and very reasonably priced. If you have more than two devices to charge in the car, you can't really do much better than this at this price-point.
Nice car charger, I have bought a note 5. And also find that tronsmart has the dual 2.0 ports car charger. Both of the ports have QC 2.0. I will get it when it is available at amazon

The model you are talking already list on amazon, check it here:
http://www.amazon.com/Tronsmart-Qua...TF8&qid=1441770789&sr=8-12&keywords=tronsmart
it's great this model comes with two micro usb cables.
I bought this charger and am mostly happy with it. It does charge at fast charger rates most of the time. Sometimes I have to plug it in a second or third time before the phone recognizes it as a fast charger. The problem I have with it, is it won't stay in the car outlet. It is so skinny, and the side spring contacts cause it to continuously eject from my jeep power outlet. It will pop out just far enough that it will stop charging with out noticing it. Might have to rig it with tape or something.

I bought the Tronsmart 2-port Quickcharge 2.0 Car Charger... Holy good god, Its become essential in my car for charging my S6 using GPS/Music Streaming. Never had any issues with my S6 or girlfriends Note 5.
As I'm sure is the case for many of you, I have a ton of typical USB chargers around the house, which supply anywhere from 0.8A to 1.5A output. Going with the assumption that I don't care how long it takes to charge, is there any risk with using the USB C-A cable that came with my pixel and plugging into any of those old USB chargers? They should all work, right? Just as different speeds depending on the output current?
I am not an expert, but from my research into the safety of USB-A to USB-C cables, the "risk" will generally come as a result of purchasing a cheap cable that does not have the appropriate (56k) resistor. The cable that came directly from google has the appropriate resistor and is not low quality, so it will be safe to plug into any functioning USB port (either on your computer or a charger).
That being said, if you have a malfunctioning charger, or there is power surge etc., that is an "act of god" and what happens happens
You may actually be better off using these old chargers if they work correctly. The slower you charge your phone, the better it is for the longevity (years) of your battery.
Yeah, that is why I didn't care about charging speed. For plugging it in next to my bed each night, I figure slower is better. However, I just received a mini USB to USB C from Amazon, and used that to plug my pixel in last night to a 1a charger. And while the phone did say charging over USB, it didn't gain any battery overnight and instead continued to discharge until I woke up in the morning. Is anyone else seeing anything like that?
Not trying to be mean or name call but I personally think you all are crazy. Buying a $700 phone and using a cheap charger that could have the risk to break your phone. Especially if you know better. Honestly, spending the $30-$40 from a charger from Google or an approved charger is just smart for the long term and not risk losing $700. Just my 2 cents. I did the same for the car charger.
Sure, I hear your point. But honestly I know that it is better for the battery to charge slower, so I would rather use a low power charger next to my bed each night, and only use the included quick charger when I need a quick top-off.

Have to consider 2 points since there are so many inaccuracies about this subject:
1) Inadequate chargers with insufficient output cause batteries to become overheated, consequently reduce battery charging cycles. Smart batteries are not adversely affected by certified quick chargers.
2) Turbo chargers do not "top off". When a battery gets to around 80%, the appropriate charger begins its slower charging as to not overload it. Once at 100%, charging stops, and the maintenance process begins. As battery level drops to around 97.6%, trickle charging begins.
In sum, a certified, OEM-equivalent quick charger, even with higher output would not damage batteries.
The phone supports most standards however usb c and Qualcomm quick charge are not compatible and you fall back to 5v 3 amp at best. Make sure to fully insert the cable into the phone. It has to click. I've accidently not charged overnight that way.
I've got a bunch of turbo chargers that I've accumulated over the years. Using a non-[manufacturer of current phone] charger has never damaged my phone. I just bought a 10 pack of USB C adapters and popped one on every charger so I can continue using my old ones. No issues yet and I don't anticipate any.

Sure, you can use non-oem chargers. That's not the problem. Issues only potentially arise when the chargers do not provide adequate output, or their "smart" capabilities are not up to specs. I use all kinds of chargers bought at Verizon, Best Buy, etc. I also use Amazon chargers as long as they're not too far off OEM requirements. Also, people don't think about the importance of a good, thick cable.
I have a ton of Samsung fast chargers and Samsung USB a to c cables . Would those be safe?

Many will say no big deal. However, I'd say let's hear it from the horse's mouth. Here's Google engineer Benson Leung https://plus.google.com/+BensonLeung/posts/cEvVQLXhyRX. You be the judge.
Bottom line, to answer your question, no, quick charging methodology used by Samsung and Motorola is not supported by the Pixel. Your phone will charge at a slower rate. Will it damage the phone in the long run? Likely not. Well, I'll let you guys test for me.
