Does anyone know the amperage of the motorola car charger for the atrix? Is it 1A.?
Swyped from 'mount' Olympus
The "Rapid" charger that came with my official Motorola Atrix Car Dock outputs 5.1V/750mA.
I have a mini USB charger for the lighter. It says 12V DC in and 5V/2.1A out, this will work fine for my atrix without harming it right? from what I know the phone actually decides how much it is taking in regardless Im told?

that is the real question...
if only we could find someone to test it for us...

mini usb won't work. the atrix is micro usb. 2.1a should work anyways. i would keep an eye on it the first couple of charges to make sure it's not getting hot though. if it gets abnormally warm/hot then don't do it anymore.
It gets warm when its on the car dock and running constantly for gps. I would think it will do that with any charger our not even charging.

Search on this forum...there are numerous threads about the usb chargers and the heat related issues with these phones while running gps or anything while in the car dock. Keep it cool and all will be OK. I have an ac vent blowing directly on mine, and I never have any charging issues.

hey guys
im not well versed when it comes to understanding voltage and etc so im asking for your inputs
i found these 2 accessories on tigerdirect.ca

http://www.tigerdirect.ca/applications/searchtools/item-details.asp?EdpNo=3973804&csid=_25
but im not sure if they'll work for x10 in terms of power/voltage/etc
any comments will be much appreciated!
Yea they should work fine, both output 5v. The car charger will charge a little slower than your stock charger (700ma vs 500ma) but it should work fine.

are u sure about that? last night i was in my friends car and he got a Motorola usb car charge... I got truly impresed how was the charging speed! awesome man! 10min 25%....
I am currently using an after market in-car type.
It works fine.
the rating is the same as the one you posted.
Input: DC12-24V
Output: DC5.0-5.5V/500mA

Positive, I'm guessing your friend has the P513 Rapid charge Moto. The reason it charges very fast is it outputs 950ma. I have the same in car charger way faster than the stock charger because it outputs 35% more charge.
So I'm coming from the Apple world and I love having the Atrix because I can just use any microUSB cable that is around. I have a question about using different chargers though. The charger that can with the phone is 5.1V at 850mA but I have some extra Motorola ones that are lying around that are only 5.0V at 550mA. Will using the other charger degrade the performance of the battery over time or will it just take longer to get a full charge?

Well it'll definitely take longer to charge but *could* cause problems in the battery. My guess is that it will judging by how others have had an "on and off" problem with lower-amperage chargers. Instead of just charging slowly the charging sort of stops and starts randomly. Leads to the assumption that the transformer in the phone itself is having trouble accepting the power. Constantly connecting and disconnecting power when charging a battery can have consequences later on.

The Atrix is really picky with the chargers. I recommend to use only the original charger or the chargers that came with the docks. People described the weirdest things from touchscreen problems to not charging at all. Charging via USB cable doesn't work either (or it is very slow), neither on the computer nor in the car.

In my opinion....
I wouldn't go as far to say "use only original chargers/Motorola chargers". The underlying issue is just like hotleadsingerguy said, lower-amperage chargers.
If you avoid these chargers, you should be fine. My Motorola Atrix charging brick/USB cable are still in their original packaging, inside the phone's box, tucked away in a cabinet.
At home, I have a few Blackberry MicroUSB chargers which I've used on my Captivate (not picky), and now they charge the Atrix without problems. They are 5.0V/700mA chargers.
At work, I pieced together some chargers from Monoprice, buying USB (female plug) power adapter with long USB -> MicroUSB cables. The power adapter from Monoprice is 5.0V/1000mA, and I use these chargers on my Atrix without a problem...and that's also using like 15 feet long cables.

I'd probably say your 550mA charger is not going to cut it, since I've seen some other threads mentioning charging problems with ~500mA chargers.
Has anyone else had this problem? I plug my Photon into a USB power adapter plugged into my car's cigarette lighter and the phone displays the message that the device is charging but the percent of charge continues to decline. I have changed USB adapters and USB cables but it still happens. If I use an AC adapter and the same USB cable the phone charges correctly.
Is it a software or hardware problem? I was unlocked and rooted using several of the current custom ROMs and the charging process in the car worked then. When I re-locked and went back to stock and re-rooted then this happened.
i am having the same issue as of yesterday. Did you ever find out what the issue was?
im guessing that the car was off and that it was a foreign car...
Numerous issue could actually cause the same symptoms, Apps/games in the background... failing alternator, failing cigarette lighter, failing car adapter...
car not running while its charging could also cause this issue depending on charge level of the battery and the volts of the battery...
What you'll need to do is eliminate the possibilities..
Try with the car on and the phone on...
try with the car on and the phone off...
try with a different adapter for the car...
try with a different usb cord...
try with a magnum 44 aimed at it...
Try with a different Car is also another good option.
Ditto.
I am having the same problem.....worked fine before I unlocked/rooted. Anyone else have a suggestion?
I have the same issue with the incar charger and using a computers usb port to charge my phone..(doesnt charge when under load ..ie-dowloading something)...i think that it is the charger being underpowered..example..
Stock a/c charger puts out 850mA
Most computer usb and standard car usb chargers only put out around 500mA

Mine charges very slowly in the car. The other day, I plugged in at 32%. Drove 30 minutes to get home, and it had only reached 37%. Plugged in at home, and within 10 minutes had well over 50%, even though I was actively using it then.
This is on stock rooted, btw.
The stock drivers must use a very conservative power draw when plugged into a relatively low-output power source. By contrast, the power draw from a high-output AC adapter must be quite aggressive, because it charges more quickly than other phones I've used when plugged into AC.
It did turn out to be caused by the car charger being underpowered. I went to BestBuy and bought a "high capacity" charger and all is good!

Which specific car charger did you get? I'm having the same problem too!
The Photon needs at least 850mA charger to get charge currently. Otherwise it charge slowly or not charge at all.
Can anyone post a link to a specific charger that is working great for you and charging fast while in the car?
has any one who got charger working ? can anyone pls post the link to product
thanks in advance

I just got my microUSB to HDMI adapter from Monoprice and it works well. However, is it supposed to maintain current to the phone? I have it all plugged in and I get an orange light on the phone but I lost 10% battery power using it for 15 minutes. Doesn't seem right?
P.S. Monoprice customer service is excellent. I can't speak to the longevity of the products but the service is excellent.

What is a 1A wall plug?
For the record, I am using the OEM plug connected to a microUSB cable I bought from Monoprice.
Uh oh. Did we get screwed?
...Sent from my Tab
I used an AC outlet 1 amp USB charging plug to power the system with a standard micro-USB cable.
People have observed problems with charging the Rezound through a car dock, so maybe it's related to that problem as well.
I tried charging using the Monoprice cable and it charged fine. If we were unsure before, I can say for sure now that it is the adapter. I don't know if it's the one sold by monoprice or, like you said, a bug in the system. Guess I can only watch 60 min. of video (tops and end up with a dead phone) or I'm out $7... kind of think I'm out the money... and no need for the cables I bought with it. Hope others read this.
The other Monoprice cables are fine. No beef with them.

I asked Monoprice about it. Here's what they said....
----------
Hello Mr. Paul,
I understand that there may be an issue with your MHL adapter you had purchased. One thing to keep in mind is that our phones are really powerful now and draw a huge amount of power. So one thing to first consider is your power draw, secondly remember most androids can tell whether it’s connected to a computer usb port or AC power supply by checking if the data pins are shorted together. Since the data pins will be in use with the MHL adapter it will never register as an AC power supply and will not draw more than 500ma of power available to a computer usb port. This is not a limitation of the MHL adapter, but rather a design flaw in the implementation of MHL itself on the phone and perhaps design flaw is a little harsh but with the implementation of the MHL on the phone, not the adapter itself. Hopefully this clears up some things for you and if the adapter isn’t going to quite work out for you I can still issue an RMA for a return for you if you like I would just need an order number to get the process started.
Thank you
-----------
Again, good customer service. Unfortunate about the phone limitations.

It is a hardware issue, the official HTC MHL adaptor does the exact same thing. (I have two of them)

Yeah, I thought it might be something like that. People were able to fix the car dock charging issue by shorting the data pins, but obviously that won't work for the MHL adapter.
I ordered one from monoprice too, I'll test it when I get home from vacation.

I wonder if a Y adapter out of the phone to split the adapter and a charging cable would work? If there is such a thing for micro usb.
Don't think so. The phone won't draw the higher 'AC' charging current unless it sees that the data pins are shorted. If the data pins are shorted, you won't be able to get data out for the HDMI connection.
Basically, while it's nice to have only one port to keep things simple, a separate HDMI port and USB port for charging would have worked better in this case.
Well then I'm returning for a GNex.
If it's tethered via usb to a computer with an HDMI out to TV/receiver can you stream from the Rezound? And would the charge via usb be enough to keep it alive for a movie?
If not then I'm definitely dropping mhs. Connection problems and this issue... Bah.

Maybe depends on what else was drawing power on your phone. If you turned off everything else, maybe you would have enough charge to stream a movie. My battery was dropping pretty fast, but I didn't try to optimize by turning off mobile data, wireless, etc...

That would be exactly the same for the same reason, while connected to your wall charger the phone can receive 1000mA and will be in "AC" mode, when connected to your computer or another device which uses the data pins your phone will be in "USB" mode and can only receive 500mA, since your phone is capable of using as much as 1000mA this will not be enough to charge your phone if you are doing anything power intensive like say playing a movie etc. It will only supplement the battery power and keep it from draining so fast.
It should make it through a movie though. I have not tried mhl so I don't know what it draws from the phone. If you instal "battery monitor widget" from the market it will tell you what your draw is and will keep a history log of it with posts every 5 min, try playing a movie then go and check the log and see what it drains on average.
My phone easily makes it through a movie if I start with a fully charged battery, although it does steadily drain it.
As far as the nexus, if anything it is probably even worse with the bigger screen.
~John
does the screen need to be on for MHL output to a monitor or TV?

On mine, the screen turns off as soon as it shows on the TV. If you unplug the connection, phone screen comes back on.

Are you using the phone to watch? Meaning is your screen on? It would seem that's the only way the screen size would matter. If you brought up the nexus due to my comment it was just a joke because of all the warring threads. I'm in love with the Rezound.
Does anybody else have an issue with their X2 when it's plugged in to either the wall or computer of the screen not responding like normal thus rendering the phone completely useless while charging? It doesn't happen every time, but probably 35% of the time which is still more than it should. And it's not just my phone either, my wife's X2 does it as well and all 3 of the X2's I've had have done it on both stock and eclipse.
Just wondering if anyone else has ran into this issue.

I believe the charger is to blame not comlatible. Not every charger is setup with same pins or wattage... if ur mis-matching equipment.

I have noticed this. With mine the keyboard becomes sluggish and the lockscreen is hard to unlock. I have eclipse now and it hasn't done that yet.

I have five different USB cables and they all work fine. I've never seen this issue before. Weird!
Sometimes mine does this not sure what causes it. Seems like phone is usually warm when it does. maybe it gets too warm with screen and charging at same time. i have had it happen with every ROM even stock.

I've used my old Crackberry charger along with my usb cord for the cpu, car and wall chargers. Havent had this problem. Strange......
Today it hasn't happened on the same cable at work.
Mine doesn't seem to take issue with any specific charger or cable except for one which is the one that was sent with my wife's phone from verizon, screws both of them up, and it's a moto charger with the same voltage/amperage as the other moto ones, but it has a 9 ft cable.
Tapped from my Eclipsed X2
Interesting it has happened on vz provided chargers. Do theyhave the Moto M on them, or sonething else?
Mine specifically is 5.1V~850mA. Has a USB cable. Has a port we can plug a cable into.
I'd be curious what everyone else has. I wouldn't think it's the cable itself but working in technology, I've seen stranger things.

It could be one of two things, either:
1. you're using a usb cable with a broken data pin.
2. you're using a charger that doesn't output enough current.
the problem lies in a lack of available current in a certain charging state, a "fast charge" if you will. you get either not a high enough sustained supply voltage, or "dirty" power (essentially a little AC in your DC) and that really screws with the capacative touchscreen.
with a bad cable, the phone thinks it's plugged into a charger and not a usb port so it will try to draw up to 850ma from a port that can only feed 500ma if you're lucky.
with a bad charger, or one incapable of supplying the required current, you get "DC ripple" where your voltage fluctuates up to half a volt or more, 60 times every second. generally your phone will get very warm under this condition as well.
so it could be a cable, a charger or a combination of both.
some car chargers are notorious for making dirty power... so are some cars...

Oddly enough I have zero problems with the car chargers, the phones work fine when plugged into them.
Yeah the newest cable is one that is USB and 9 ft long but not moto one that verizon sent with my wife's phone. The moto one that came with mine an the two moto ones I got from Amazon I don't have any issue with but the cables are so stinking short they are a pita to use anyway (2' cables).
I've also noticed that the USB ports on different computers charge at different rates as well. My work computer will barely charge the phone and sometimes can't even maintain the battery level if I'm using it. My laptop at home charges it pretty good but you can't use the phone because you get the screen issue again.
Tapped from my Eclipsed X2
Yeah, I have had this same issue for quite some time and after reading this forum tonight I tried a new charger and BAM, problem fixed! I had thought it was my phone, but it was definitely the charger. The one I was using was the Verizon 9ft charger they send out with replacement phones. Model: B141000. Black with green on the back. Gave my wife my charger that came with the DX2 to take to work and use because I liked this big long cord. So for months now whenever I tried to use the phone while it was charging it lagged so bad I would have to continuously unplug it and plug it back in when I was finished. Needless to say, having a text conversation when battery was almost dead was really annoying...
So when I read this post tonight I went up and grabbed my old Samsung charger from my old Samsung Fascinate and sure enough it worked just fine... No lag what so ever. So I am guessing it is an issue with the DX2 and the generic Verizon charger they send with replacement phones not being compatible...
Furthermore just as a test I just tried the actual 9ft USB cord with the Samsung plug you plug into the outlet and its still working fine... So I assume its the Verizon plug part not putting put enough voltage or something. Pretty happy that I can seemingly still use my 9ft cord! So if you have a spare plug I would say give it a try!
