Charging from external +5V source - Atrix 4G General

Maybe some of you bought external charger, battery or like me, solar charger with battery and realize that Atrix doesn't charge but other phones does. Solution is quite simple. Only what you need to do is to put resistor about 200OHM or just short USB data pins (2 and 3) in your charger or cable. I really recommend to put resistor. Interested thing is that after phone is connected you can remove resistor and charging will continue.
1 VBUS Red +5 V
2 Dāˆ’ White Data āˆ’
3 D+ Green Data +
4 GND Black Ground
I tested today

I made a 12 to 5V 3A converter for my wife's car. It works well with her HTC Evo 3D but for my Matrix I had to add 20kOhm resistor...

20kOhm? Thanks, bigger resistor, less current. I just tested 330kOhm and it works

[Q] car charger

hi, just got x10 but i have for it 2 car chargers and both not working, does anyone know do i have to change some settings in phone? cheers for any help
Is your car lighter ok?
i have a similar problem,.... i have a USB cigarette lighter adapter that i used on my previews phone,....
it doesnt work when i try to charge my X10,... (im using the original SE data cable,....)
A lot of the standard car chargers won't work for X10 for some reason.. they must be wired slightly differently.. you need to order one which is X10 compatible. I had a Jabra adapter which I tried with my USB cable and it didn't work..
Also - This thread should be in the Accessories section. MOD - can you please move?
Thanks.
Just a note of advice here... Make sure you're using a USB POWER cable instead of a DATA cable. If you're using a cable other than the one supplied with the X10, it may not work for charging.
FYI: The Motorola microUSB chargers work perfectly fine with the X10
There is a fix for your problem in this forum. Take yourself a digital meter or something like this and check if there is resistance.
If they are not connected (I bet they aren't) just solder the two data pins in your charger together (middle pins). Then it should
work!

ya, my blackberry car charger works perfectly with the x10
I bought 2 chargers the other day. They both worked. Only paid $3.50 per charger too and got free shipping because I have amazon prime:

I'm using the Nokia charger and it's working great so far.

[Q] Chargers compatibility

I have bought a usb charger on ebay, but it doesnt work with X10, any solution? Why?

1. This belongs in the Accessories section
2. The answer to your question: because the SE charger has the pin 2 and 3 (the data pins) of the USB pinout shorted. Normal chargers does not have these shorted. Don't ask me why, it just seems stupid and proprietary to me.
Can you explain better? I cant use others chargers? I cant use others microusb cables?

You can use a charger from a blackberry 9700, for sure and the 9000 I think. The bit about pin 2 and 3 shorted is true. I have a cigarette usb charger that came with my bluetooth gps and it would not work with my Iphone/ipod nor with my X10, I shorted or joined pin 2 and 3 ( the middle 2 pins ) and now it works just fine. That unit you bought is it not for the iphone? So you can open up the charger and short out pins 2 and 3 or modify the cable. I suggest you label the cable for charge only as I think it will not allow data to flow.

Superportable and supersound. Builtin battery lasts approx 12 hours per each speaker.
Charging via USB, possible to use Defy (but not so wise...)

@goateye yeah thanks, i'm big fan of Logitech, recently, i will decide between X-Mini and Logitech Z120
I have the x-minis too - they are great little speakers

Note 3 usb charging overseas?

Hi everyone I just have a quick question
Right now I'm overseas and the power voltage of this country is 220 v .
I forgot to purchase a wall adapter to charge my phone but luckily my cousins here all have note 3 's
Is it safe if I just plug my usb (that came with the phone) onto their wall chargers/aftermarket wall chargers ?
Here is a picture of my setup

This is very basic. You should always check the charger or any appliances if it has/supports 110V-240V input. Be vigilant.
All chargers have 110V-240V input range, and any usb charger can charge the phone. Check the output amps of the charger, if its lower than the stock charger then it will charge slowly, if its higher than the stock charger then it would charge fast but could damage the battery life as well. Otherwise any USB charger will works fine just after market cheap one may does short-circuit or over heat issues.
Thanks everyone

It's been rather hit or miss with car chargers. Have a look over here: http://www.droid-life.com/2015/10/19/nexus-6p-nexus-5x-quick-charge/ As you can see, you might get really good results with that, or you might not. I've had good results with their products, so I personally wouldn't be overly concerned. The point is though - we won't know until someone tries it and reports the results back.
If you're buying through Amazon, you can always return it. Go get the Ampere app from the play store, plug it in to that charger, and if you're not satisfied with the results, send it back.
I suggest the tronsomart. It's not true 3A but it'll be good enough.
Good
many one are using this charger and it is really a good one for long drive.
I can confirm it the 6P does at least display the "Charging Rapdily" message when using this charger though it won't take advantage of the 3A the 6p can handle. Seems to work fine.
