last week i were on a holyday where i really didn?t have access to any form of power (that is unless i went into a store to use their power to charge my xda2 where i then had to wait for something which felt like a year for it to get some power)
needless to say that i didn?t use my xda2 all that much for that week
I remember that you for normal cell phones can get different types of funny chargers
Like one where you have to turn some handle to produce power
And also one which used solar power
Have anybody had any experience with such types of chargers and the xda series ?
I mean sure they would prob not have the right connector but modding one yourself using the connector from the charger to connect a modded wire would be a walk in the park
Hi Rudegar,
have a look at
http://secure.proporta.com/proporta/F02/PPF02P05.php?t_id=657&t_mode=des
Proporta iSun
I was thinking on buying the Proporta iSun...
That would solve the problem Rudegar had!
And of course it was a right good suggestion from bejay!
So anybody has it?
When you buy it does it comes with the right Himalaya cable?
Tnx.
Any charger that supplies 5V on a "sony walkman style" jack plug (+ on tip if I recall) will do.
Most chargers come with a variety of jack plugs.
The jack plug goes on the charger-to-mda-plug converter that was shipped with your device.
Worked for me in the car when I had no carkit
I just purchased a Covertec travel usb charger + car usb charger + usb cable for $19.95 + shipping from Mobileplanet.com Search covertec xda on the site. The DC 5V output is rated at 850mA or 1A. There is a review up on pccw.net.
I like the usb solution better because I can reuse the charger for most new cell phones, blackberries, pda etc. So I only need to carry one power source instead of 2 or 3.
There is another USB high current charger wiith a brand called Ecovell which costs $15 just for the AC charger.

For my it's a little bit expensive...
But who has core can buy it!
I'll remain on Proporta iSun solution.
http://www.coolpromotions.co.uk/rotarycharger.htm
i would asume this one is even cheaper not sure how many volts it give however and if using it could damage ones xda
also since it give somewhat less then 1 to 1 charging to 100% would likely take a great deal of time but hey they say we should get some workout once in awhile
good stuf for a reasonable price: www.time168.com
(also on eBay, but cheaper when bought directly)
Ordered a universal one with wall attachment and car attachment and when I connect the USB to microUSB cord the phone doesn't charge. Ordered another stand alone car charger and it, also, doesn't charge. If I attach the USB cord that came with the phone to the wall/car charger it charges fine. Both, specifically said for the "Nexus One". Is it an amp issue? Most microUSB charger in the mall cell phone kiosks won't charge it either. Is it a proprietary microUSB cord that I need or a matter of amps or something?
Why not buy from Monoprice.com?!
I ordered 8 USB cords (2/each of 4 different lengths), 2 Car Chargers, and 2 Wall chargers. All work perfectly fine, and I paid under $25. (Wife has a CLIQ, so we got plenty to work for both of us.)
So, I don't know what your issue is... Other than just not going to Monoprice

well I havent ordered from monoprice since customers got slammed with bogus charges... i guess i could give them another try though, but still... kinda weary
Why? I had over $1300 attempted to be spent at Newegg, and my CC company called me and stopped the charges. Got a new CC in the mail the following day. Some random amount at Apple as well. LOL. Fun times.
(Yes, it happened to me. I'm fairly confident it was from the same issue as others..) But, that doesn't stop me from using a company that makes good products, expecially when they just made such a big mistake. Odds are, it won't be happening again for a long while
Either way... Those are risks with online shopping. You just have to make sure that your method of purchase has fail-safes.
I have a CRAP load of mini USB chargers (all HTC stock) and didn't want to buy more. I bought a bunch of Motorola mini to micro adapters off Overstock.com for $2 a piece and couldn't be happier. I also bought the official Google cradle to avoid additional wear and tear on the microUSB port.
-Mc
I bought a car/home charger from eBay when I had my Motorola Cliq, and my home charger would keep going on/off charging. I later found out that it was the voltage issue, where the charger was giving a maximum of 5 amps and the Motorola Cliq needed 5.1V or something like that.
But most chargers I've bought don't power the Nexus One. What specific voltage or amps should I look for it to have? The two I bought off of eBay specifically said they were for the Nexus One. Neither worked. Sellers are putting any micro SD chargers up for sale assuming they will change the phone. They will not. What technical spec will tell me if it really will charge it?
Could someone post a link to a USB charger that absolutely works? I just bought another one from Best Buy that doesn't charge the Nexus. Made by Rocketfish and is suppose to be universal.
Thats really wierd. Every charger i've tried works fine.
You're charger should be outputting 5V and anywhere from 300mA upwards. There is no max mA limit because the phone will only draw what it needs.
This might sound patronising, and I really dont mean it to, but when you say doesnt charge how do you know?
Do you mean from totally flat it won't turn the phone on and start charging it, or do you mean when the phone is on the battery indicator doesnt show a charging, and the LED doesnt go orange/green?
Or do you mean it never charges to full?
When I plug it in it's as if nothing happens. No light, no thunderbolt symbol on the battery, no screen wake-up, nothing. Nada. Now, the HTC wall charger and usb charger work fine. But if a MicroUSB charger calls itself "universal" it does not mean it will charge the Nexus. The HTC HD2 charger my wife has works fine on the Nexus though.
Hmm strange.
The charge process works like this:
- Charger plugged in causes voltage change on +ve USB line - potential charger detected.
- Phone draws minimal current (50 to 100mA) and tries to negotiate USB power
-- If that suceeds it tries to increase power to 500mA if the USB port supports it. If yes charging starts at 500mA, if not charging starts at 100mA
- If USB negotiation fails, it checks if D+/D- are bridged.
-- If D+/D- are bridged, the phone draws as much current as it can/needs
-- If D+/D- are not bridged, the phone draws a max of 500mA
There's nothing special about the chargers unless they have been wired in some special way for a specific phone. Thats why I'm very surprised these chargers dont work.
I know that if I chop a USB extention cable and cut out D+/D-, my nexus charges at 500mA. I've tried this myself for a totally different purpose. Thats no different to ground and power being wired to a 5v source.
Odd, I have three car USB adaptors and two AC USB adaptors.. All charged the phone, although only the AC charger shipped with the Nexus would do a fast charge, and none of my car chargers would. I found one that was rated 1Ah and soldered the two middle pins, now it works as a fast charger too.
The Motorola P513 car charger (OEM designed for a Droid) gives out 950mA, is super cheap (~$3+shipping), and works great for a fast charge with the Nexus One.

Thank you sir. I've been trying to find a car charger that guarantees a fast charge.
Just ordered one from Play.com for £3.99 w/ free shipping.
Maybe now I can use GPS for more than an hour...
I dunno.
My motorola charger for my old bluetooth (H780?) works fine, as well as the original google charger. I also have a car charger for my old bluetooth as well.
My suggestion, is to only buy name brand chargers?

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?
Logicalstep
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.
Hello,
I think I am going to get a transformer, however the availability and price in Spain is insane and I will get one probably from UK, the power adapter there is not compatible with the stuff that we have in spain. Is it possible to charge via the computer USB or by using any other USB charger with a USB input like a HTC charger?
Regards,
Isaac.

You can charge via USB from a computer, but it will take 24+ hours.
You can also charge from an iPad power adapter.
I am thinking of doing the same thing myself...
But I am trying to bring one from the US one I got there (i am going there on a month). I am expecting the AC adaptor works with 110-220 Vac and I will only need a plug adaptor (one you can get almost on every hardware store).
I would be glad if you kept me updated about any thing yo do / discover.
Regards.
Hi
Im searching for a car charger for the nexus 4 that will charge the device even on navigation running...I now that the Motorola Rapid car charger was good with the galaxy nexus.I dont know if itS ok with the nexus 4 because on the LG charger it sayS 1.2A?I read that the Bracketron Universal Dual USB Car Adapte 2.1A will just work as AC charger if plugged in with a USB charging only cable...but i cant find those cable to order online here i Canada...and i dont wanna do it myself and modify a regular usb cable ...Soo if someone can help me it would be much appreciated.

You dont have to have a modded cable if your car charger already has the data pins shorted. Im using the motorola rapid charger too and it works fine, it will charge your phone as AC and give enough power to recharge the battery with navigation on. if you want something a bit better you can try this one , they ship to canada. My rapid charger broke so i bought it a few days ago. Reviews says the trident will give around 8-900mA, the moto charger outputs around 6-700mA.
I would only buy a premium brand here. If you see how no name mains adaptors are made... the risk of blowing up something expensive is just too big.
I wnent with the Sony AN-400 / 401, because it is rated at 1.2 amps exactly, is small, and was reported to work fine.
For some regulator disasters:
http://hackaday.com/2012/08/15/buying-cheaper-electronics-and-not-saving-money/ <- a USB car charger without components, putting 12 volts straight on USB.
http://www.youtube.com/watch?v=wi-b9k-0KfE <- teardown of imitation apple mains adapter, showing no output protection and very little gap between mains voltage and output circuit. Good info, but style of presentation is not my cup of tea.
So that is why I went with a premium brand.
that's one charger from one factory that some guy that didnt know what he was doing and ordered thousands, without testing them. He probably went for the 25 cent super deluxe model...
Well reviewed chargers from xda members here and not to mention the hundreds of people on amazon are a safe bet. Here's a 8+page thread on the charger i linked. Your premium brand name sony charger is made in china too.

If you're into rooting and custom kernels, most of them have a fastcharge option where you don't need to have a special usb cable, or, attempt to short the D- and D+ lines.
Monoprice has a 2.1A bullet charger for a bit cheaper:

i cant say for sure until i get it sometime next week but i think so. im in canada too and couldnt find the powergen anywhere that would ship here.
There are some other brands that are good too but i like this one cause it's dual usb like my old moto rapid charger. If you dont need that you can get some smaller ones that will work just make sure they are well review and can output around 1A. The one that bfspider spider recommends is a good bet too since monoprice is pretty reputable store and will ship to canada.

You can try to mod this one in the mean time, just take it apart and attach the two data pins(they are the two middle ones). Solder is best but if you cant you can just use pilers and bend the pins until they touch. i did this with a few of my chargers too and it works to make them AC but it wont increase the output if its low to begin with.

FYI, this adapter should allow most existing "iPad" chargers (1.2A or higher) + any USB cable to work well with the Nexus 4.
The problem is that Apple products deviate from USB charging standards. As a result, most chargers try to be compatible with iDevices and also deviate from the standards. So when standard-compliant devices try to follow the standards, the chargers refuse to follow the standards, and the devices get upset with each other. Fortunately, they fall back and settle on a lower-power charging rate.
If you want to buy chargers that are very clear on what they support, check out MediaBridge (also available on Amazon).
Why does a bog standard USB cable work in the car for me? Using a proper off-line sat nav my phone was fully charged

So i got that Trident charger that you recommended....the quality looks good...but when I tried it in the 1A and 2A port with the usb cable that comes with it,it shows USB charging but when I use the HTC usb cable that came with my HTC one S it shows AC charging....its so confusing and I just dont get it....that HTC cable is a sync and charge cable.
The generic T-Mobile car charger available at T-Mobile stores charges just fine. I believe it is at least 1 amp. Its black, has a purple white small led indicator when charging. The USB end looks like a little block and the cord is an accordion type and it also has a a female USB slot in it to plug something else in at the same time but I believe whatever USB cord you plug in there only charges at .5 amp. With this charger I can run navigation and Bluetooth and Pandora and message at the same time and it will charge.
Sent from my often RMA'd Nexus 4, So that I can use the one I'm using now when I get the 6th and hopefully final one.
I just dont get it why does it with one cable show USB charging and with the other HTC cable AC charging?:S
