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.
So, I may be the only one in the world who doesn't want a fast car charger... But, I'm looking for some recommendations on a "regular speed" car charger.
I know a lot of people are of the "I want it charged faster, consequences be damned!" variety but, I would rather not inflict damage to my battery from quick charging.
You need at least a 1 amp charger to charge and use GPS at the same time. The phone has circuitry in it to prevent "over charging"I use one I got from at&t. It has an additional USB port on it to charge two devices at once

I use this with standard wall charger.
Sorry don't know why my links are messed up.

Hi all,
When I use the charger that came with the HTC One my phone charges great, rapid.
But when I use any other charger that I have in my home/office it charges very slow. Even with a 2.1 amp charger!
The charger that comes with the phone has an output of 1 amp.
I've tried multiple other chargers (1 amp and 2.1 amp) and they all trickle charge.
Anyone else noticing this?
Thanks
Joe
I'm using old charges at home and in the office and it did seems slow but had not heard of rapid charge. Will the phone indicate this rapid charge mode? If not, is it real?
I'm getting slow charging even on the stock HTC charger. Not sure how I can enable this rapid charge cause 4+ hours from 0-1% to full is a bit ridiculous.
use orginal charger is best , maybe it has some relationship with your battery life
If anyone is coming from phones with smaller batteries, remember the larger the capacity the long it takes to charge.
I use the cable and charger from my Nexus 7 and it charges fast. Off my USB it is slow.
Real AC chargers have two pins shorted. You can hack a USB to micro USB cable and short the same two pins to enable AC charging with any adapter, wall, USB, or car. Should be pins 3+4, but don't hold me to that.

i've done exactly this, and damned if the One still refuses to draw more than ~500 ma off of anything but the 2.1 A wallwart it came with (i don't have any others to try with). i'm about to dig out an old inverter to see if that will actually work. wish i'd paid more attention to my EE dad when i lived at home; i've gotten a serious crash course in this stuff while trying to get my One to charge in my car, when it's on.
edit: so i got my old inverter out, and spent about 15 minutes testing. i used the 2.0A adapter that came with my Nexus 7 to test, as well as the 3.1A Mediabridge adapter i got here. my phone was at about 45% when i started testing. unplugged, Battery Monitor Widget reported a drain of anywhere between 500ma and 650ma (running Ingress, wifi on). plugged in to the Mediabridge adapter showed, at best, a drain of 50ma. the Nexus adapter plugged in to my inverter charged at a fairly consistent ~120ma. i didn't touch my phone the entire time.
i left my Nexus 7 at work so i can't use it to repeat the test, but i will do so tomorrow. the cable i'm using is this one. i'm not crazy about having a ridiculous DC-AC inverter in my car for my phone, but if that's what i have to do so it can be used and not drain, then so be it. admittedly, i don't really understand these things enough to explain these variations, but i plan on learning ASAP. perhaps somebody else can shed some light on why the device charges different, and how it identifies an AC-USB adapter vs a DC-USB adapter.

Math doesn't support what is happening though. Phone has a 2300mAh battery. The OEM charger outputs 1A (1000mAh)
At most, it should be around 3 hours for full charge, when in fact it is closer to 4-4.5 hours. It's the last 10% that is the issue, it will trickle charge to 100% rather than rapid charge.

Yes, I think that's exactly what the HTC does... I read a pretty good article recently about Li-Ion batteries that talks about how trickle charging is the best for battery life, and it wouldn't surprise me if HTC got a little aggressive the way the this phone charges since we can't swap the battery ourselves.
I'm trying one last car charger, which matches the wattage of my Nexus 7's 5Vdc/2A AC adapter (which I've had the best luck with, when charging the phone while in use): http://www.amazon.com/gp/product/B009TBF7IG/ref=oh_details_o00_s00_i00?ie=UTF8&psc=1
If that doesn't work, I'm going to put a 300W inverter in my car with the AC adapters themselves and stop buying stinking DC adapters. This phone clearly pays very close attention to the wattage available from whatever it's plugged in to.

My next car will too, because I can only imagine that power requirements for these devices is going to increase.
That said, I think I have a winner, and instead of retyping my posts, I'll just link to that thread instead: http://forum.xda-developers.com/showpost.php?p=41797839&postcount=6
Since the snap Dragon 600 has fast charging capabilities, why didn't HTC Include it in the kernel??? I've noticed my 2500 mAh note battery charges faster than my 2300 MAH HTC one

Just FYI I just bought this http://www.ebay.com/itm/190961745241 and it fast charges my G2. It has model number ETA-U90JWE on the unit. Just thought I'd pass that along since I was having so many problems finding the right charger/cord combo that would fast charge.

Thanks! Just bought one as a backup charger
I got two of those a week or so ago myself from eBay (same model charger ETA-U90JWE, different seller, etc.) and can confirm that they QuickCharge. I was a bit worried after reading some reviews on Amazon.com that there are knockoffs of the same model that perform poorly but I guess I got lucky.
Those that have it -- does the USB cable work with the original charger too? and with other 2amp chargers (like my car charger)? I always leave a AC charger in my car just in case, but if it's going to take 5 hours to charge my phone, it becomes pretty pointless unless I'm staying overnight somewhere.
This is okay but remember kids. Slow charging is much better for your battery

Yes, the white cables that came with it do fast charge (tested with both these new Samsung charges and stock LG unit). From 10% to full charge in about 90 minutes.

Nothing sucks worse than going out and having a dead phone.
Although I'm up to 30 hours so far and have used only 63%
Has anyone found a car charger that will fast charge? I now have 4 chargers that claimed they would but will not. My wife's work phone has that charge above. It works great.

Charging times with any electronic device are dependent on amperage. Find a charger that is 2amps and you should be set. It will say on the box.

Lies! These aren't ****ty old NiCa batteries. If it doesn't heat bad, which i haven't experienced in fast charge, its perfectly fine. Screw the base brick, I'm just trying to find a single USB 3.0 (needed) supported cable that supports 1800mA. Not one that runs over 800mA and doesn't pop slow charge, but one That fully utilizes all the mA's. Can aubergine post a SS of the mA reading please?

Here is one I ordered from Amazon, it arrived today.
http://www.amazon.com/reVOLT-c2-Dua...=1384487213&sr=8-3&keywords=scosche+revolt+c2
I just tested it: I have a 110v wall plug to cigarette charger socket adapter. Plugged my old cig charger into it, used the white usb cables I described in a previous post in this thread, and got slow charge message. Then I took out that old cig charger and plugged in the new Scosche reVolt c2, used the same cable and got no slow charge message. Watched it for 2 minutes and it went up 2% (so I consider that QuickCharge).
Thanks

Just bought one of these. Thanks smacklayer!!!
Weird. This thing is picky. The usb cable with my 2.0a csr charger charges at around 900mha, but plugged in using the samsung ac adapter it slow charges at 30mha... but once in awhile it goes at 800 to 900
Thanks smacklayer - I bought one just like yours on eBay.
One has to be careful not to get a gray market knock-off, but it's hard to tell exactly. Even on Amazon, there are lots of complaints of chargers that appear to be OEM but aren't.
BTW: how does one tell if their G2 is NOT "fast charging"? Is there some indication?
I have a PowerGen 2A car charger with usb cable that I purchased a year ago for my N7. I plugged my G2 in the other day and I didn't see any visual cues that something was "slow charging" and it appeared to charge just as fast as the LG G2-supplied charger. So, I've been wondering about a "fast" or "slow" charging indicator.
Thanks in advance for your assistance.

They have these available at every Walgreens, I can confirm they work with 2A chargers. I know they are ugly and awkward but if you're in a pinch and need one right away these are easy to find. Usually found around the register area.

How is this even possible? While using NAV, my G3 is plugged into the car charger is still decreasing in battery life. Albeit slower than when not charging, but it still goes down even though it is charging. What gives?
Using a charger bought at VZW.
Make sure the charger is 2.1 amp...if its a 1 amp, the combo of GPS, data, and screen on will still kill it.

Yup, totally depends on the charger. Some cheap ones are only .5A and most are 1A, which probably still isnt enough when using GPS and screen on.

How is an old iPhone charger going to help anyone with a G3? Also, what is "this quality"? I think you might've lost or misspelled a word there.

I had this problem starting all the way back on Galaxy Nexus - crappy chargers and cables do not provide enough power to run the phone and the screen. My research and trial and error on many chargers lead me to understand that not only do you need a good high power charger, you need a good cable too. I now run 18awg charge-only cables exclusively as well as a 2.1amp charger. This pair has worked on all my devices since including fast charging on my G2 and G3.
Note that a charge-only USB cable has the data pair shorted and will only work for charging - will not work for data transfer. However the wires inside are thick and work great cars or other situations where you don't need the cable for data.
This is what I use:

This company is from Hong Kong, but they have pretty fast shipping. It is the only place where I can find (affordable) heavy gauge USB cables.

I had the same issue with a store-bought charger. It also depends on the amperage output of your vehicle's outlet as well.
If anyone is looking for one with a retractable cable, I bought this one:
