I'm not sure if this is even possible and sorry if it has already been answered, but is there a way to make the A500 micro usb port actually charge the tablet? I know it doesn't charge thru that port now, but is there a mod that can be done via software tweaking; or is it a hardware issue that can't be changed? It would be nice to charge the A500 with a micro usb cord and especially in the car with my Thunderbolt's car charger.
Microusb does not put out enough juice to charge tablets effectively.

From what I understand, the USB connection won't provide enough current to charge the batteries sufficiently, so I would say no. This is the same on the iPad as well, no USB charge like is possible with the iPhone. The dock (shown on the Acer website) will at least allow another charging option, albeit probably not what you had in mind. Best thing to do is probably just get a power inverter for your car and plug it in.
I don't think there is enough electrical current through the USB port to charge the device effectively. As USB can only give you 5v 900mA, this device requires 12v 1.5A to charge.
Oh, gotcha. Thanks everybody, it makes sense about not putting out enough juice. I wondered if it didn't charge maybe because Acer didn't design for it to, and it was strictly for data transfer; which it is.
I've always wondered why they didn't include one of the double ended USB plugs like DVD burners over USB use. Still 2 x 5V x 500mA(900mA is USB 3.0 only) isn't the same as 12 x 1.5.
Personally, mine gets it's power from it's molecular density's proximity to our yellow sun. I've also named it Zod.

I got this car adapter from Wal-Mart (it's a universal adapter - Powerline Model #90293). It's a 12V 2A adapter (originally bought it for a Viewsonic G Tablet...couldn't find a 1.5A version). It works well with the A500...the adapter plug sticks out a little bit, but it's not a big deal.
As long as the amperage is higher and the quality is as good or better, any DC adapter would work. It just needs to fit in the hole.
USB 3.0?
Would using a USB 3.0 port and cable make a difference since it carries a higher charge?

No. It's simply not wired to charge the tablet. For the same reason you can't charge your laptop via the USB port.

Ok since USB charging is out of the question I have another. People who have used the Xoom, is the Acer's charging port the same as the one on the Xoom? The Xoom has an official car charger, but just by looking I can't tell if they are the same size ends.

You could probably head out to BestBuy or Staples etc.. and compare the 2. They should be side by side. Otherwise, I'm sure Acer (or some other 3rd party) will probably release a car charger that plugs into the proprietary port on the bottom?
From what I remember, the Motorola charging port is like a little thin nubbit. I think the plug on our Acer is larger. Check it out and post some pics.
My charger's head got broken into half just now ==! Hopefully can get the warranty.

If the usb port on this phone is a non-standard size I am going to be pissed.
I loved that the mt3g uses a regular mini usb plug because pretty much everyone and their mom has something lying around the house that uses that size. That means that wherever I end up I can always find something to plug into and charge my phone.
I've used camera cables, blackberry chargers, even used my buddy's ps3 controller cable to charge my phone directly from the ps3 or the cable box, lol.
Can anyone enlighten me before I buy something from Ebay that I don't need?

Came across a thread in my googling that indicated there were two styles of micro usb. Also a coworker's phone (Captivate) has an equally small but differently shaped port.
I assumed one of the two ports (mine or hers) had to be non-standard, just didn't know which one.
Thanks for answering my question. So this should work just fine?

I've been charging mine on an old LG charger I had lying around and keep the supplied micro USB cord with my laptop.
side note: I just ordered some Motorola right angle adapters from Amazon for 4 bucks each... I HATE the location of the USB plug; it makes landscape suck and charging at night is a pain logistically.

Oooh, right angle adapter is a good idea. Agreed, the charge port location sucks balls, but I assume that was a necessity.
Just wanted to tell my fellow US Note users that I found what I deem to be a great deal for a fantastic US charger.
I didn't have a converter to use the supplied European charger, so I used my old Motorola Droid X wall wart and USB cable. It worked fine, but I noticed that it made my touch screen a little less sensitive. For instance, it might make my Swypes on the keyboard break into separate lines, confusing Swype. It charged my phone, but the battery got warm; I thought all of this was normal. I tried another charger, an LG one, just to see if that changed anything, but it worked about the same.
Then from reading around, I realized that the standard charger is a 5v 1.0A charger and both chargers I was using were 5.1v 750mA/850mA chargers. I immediately started searching for a direct replacement and only after a long search I found a Palm Pre charger with the exact specs as our Note's.

I assumed it would charge faster being a 1A charger, and it does, but what I didn't expect is what pleases me the most: the screen sensitivity when charging is immensely improved (Swype is exactly like without the charger in) and the battery stays dead cool! It is around 5c cooler according to SetCPU. Just awesome!
I'm so pleased I wanted to share. I hope this helps others who may have experienced similar issues.
The link is below (not sure if I can link directly to an Amazon item, hope this isn't against the rules.) It's super cheap and the quality is top notch! Soft touch plastic on the wall wart and also the USB cable! I just bought another as a backup. It's only 3.49 w/ free shipping!
BTW I bought it from "BobTronics" because some reviews said they got what might not be genuine Palm USB cables from other sellers. Mine is legit; it has the palm cable tie and feels high quality.

As a Palm Pilot -> Tungsten -> Palm Pre ->-->Pre 2 user I have to agree.
I have numerous chargers, some even labelled at 1.0 AMP, but none as good as the Palm charger. Just well built, FULL 1.0 Amp, and so pocket able.

I wonder if that causes any unnecessary stress/strain on the battery or the phone itself. I was worried about the heat that came off of my phone w/ the Droid & LG chargers, probably more due to the 5.1v rather than the amperage though.
I have the same chargers that came with my HP Touchpad during the fire sale. They are excellent chargers and I also use them on my non HP mobile devices as well.

Note's circuit limits the charge current at 1 amp.
2 amp Improvement is imaginary/placebo as charge times are exactly similar to 1 amp.
I have a Galaxy Tab charger rated at 2amps and it takes exa tly the same time to do a full charge as with the bundled charger at 1 amp.
Hence, no need to worry about temperatures.

In that case, I am even happier w/ my 1A charger.
I have used my new Nexus4 on the road with google navigation. I was surprised to find out that the 1Amp samsung charger I have used with my SGS2 was not able to maintain the charge of the phone. After couple of hours of driving my Nexus 4 died ( I didn't start with full battery)
What is your experience? I would expect the phone not only to work whilst on cable for the whole time, but also to eventually charge the phone fully.
Now I am not sure if it is my charger or nexus 4.
I had a look on mains charger and the output is 1.2Amp, is this the problem, that the car charger is not powerful enough?
I currently use CAD300UBE, which is the official i9300 car charger, with a rated output of 700mA.
When streaming over bluetooth using Spotify, and using Google Navigation I can say that this charger does charge the phone.
My old S2 charger, also genuine did not manage to charge my S3, hence the replacement.
Phil
My recollection is that Nexus devices are looking for pins 2 and 3 (data) of the charger to be shorted. If they are not, you'll only get 500ma from the supply.
Turn the screen of when not needed in navigation,
I use a kensington 2A flush cigarette lighter so it isn't an issue, the charger is <$15, and it makes life easier when I want to charge my ipad. Only thing I regret about the charger is that I didn't get the dual port version.
I posted this in the GN forum about a year ago when the same sort of problems were coming up there. You need a 2A charger and a data only cable to make you charge like you are on a wall charger. (Charging AC - Check this by going to Settings > Battery, the top shows charging AC.

There was another thread, I think in the General that discussed all of this, what people came up with was the best combination if you want a dual port usb charger is to make sure you have a "charging only" USB cable. This cable will not make your phone think it is connected to a computer. You can tweek a data/charging cable to work but some people messed that up so it is probably worth just spending the $4 on a cable that works.
Here is my combination that works great. With this set up I can have on my navigation going with the screen on the whole time and stream Pandora over Bluetooth into my car and the battery still charges really quickly.

Thanks!
Do you use the cable with the original LG Charger ?
The LG Charger is 1,8A output.
The commons chargers and USB on computers are 1A output.
SO if you plug in your cable to a computer or other charger, it's normal.

from the D802, but really just try another cable to the charger if it makes any difference.
Hmmm, that is definitely different than what I believe to be the cable that came with my G2. Not sure how to tell what version of us, but it's Verizon.
But yes I have tried many combinations of cables with the LG charger and none of them are fast charging. Using CurrentWidget and a couple other battery monitoring apps, I've also found that I get a much higher amperage draw from the charger that came with my galaxy s3. Anywhere from 200mA - 400mA, whereas I only get 50mA-150mA with the cable in this pic and the 1.8mA LG charger. But still all of then state that they are Slow Charging.
Can someone tell me if this is the stock LG USB cable?

You would be surprised how many times an USB cable matters, and then again when it doesn't.
For example a chromecast USB cable which I accidentally got, did not charge my phone almost at all and not DATA connection was possible. But that was a clear error and I do not think that cable should be used with anything but with the Chromecast being nicely shielded and all.
ASUS in my country uses same cables as the one pictured above (Still does not mean that his is not original LG). But if you get a normal connection on the computer same goes for AC , USB charging in places where they should be, use whatever cables you want.
Stay away rather from too generic, skinny unbranded ones from chinese pages. (Even though from them I always buy iPhone cables . BUt who would pay 15 bucks instead of 1 and they served my wife well)
So far ASUS, HTC, Samsung , LG, and Nokia cables did there job mixing across my devices.
Verizon stock cable.

Pagot - YEESS! I acutally used my Chromecast USB cable (which I'll be returned on Monday btw cause, well its just not that cool) ALL NIGHT LONG!!! I didn't think anything of it plugged it in and immediately walked away. Little did I realize, it was one of those cables that, 5 seconds after plugging in, reports that you should unplug it immediately to avoid damaging the phone!!!
I didn't see the message until the next morning and saw that my phone didn't get charged that night. And for about 2 days, I had VERY strange charging issues.. (see this post) I think they've gone away now, except that my fast charge isn't working.. But, back to the original purpose of this post, Im hoping that is USB cable related..
Anyway, it was the wierdest this, for about 2 days, certain chargers and USB cables that have always worked on this phone, didn't. The first day nothing but plugging into my computer would register any charge.. By that night most chargers worked but some wouldn't provide more than 50mA, and now, all of them seem to be working again..
SOOO, moral of the story is that in incorrect USB cable CAN damage your phone! At least temporarily.. Still doesn't make any sense to me how though.. Perhaps some protect feature kicked in and caused the symptoms I saw, but all I know is that my phone wouldn't charge anymore after using that Chromecast cable...

There is a thread in the G2 Accessories forum discussing compatible cables.
http://forum.xda-developers.com/showthread.php?t=2460881
I was doing a car install of my Nexus because I wasn't really using it for anything else. I wanted a good power source so I could avoid the charging issues people were running to, so I went with a DC-DC converter instead of a cigarette lighter adapter. I used the same converter that many others have used, and dialed it in to the correct voltage output and wired it up to my USB-OTG Y cable. I plugged it into my tablet to test, and the system immediately shut down and got really, really hot. After I unplugged it and let it cool off, I was able to boot the tablet, but it no longer charged anymore from the wall socket adapter. I woke up to a dead tablet and started troubleshooting. I was tracing the power circuit and was seeing 5V everywhere except for at the battery connector. (Battery tested fine at 3.7V). After removing the metal shield inside the tablet I found this:

Needless to say, the thing is toast. I wish I knew what happened, but I don't. Everything appeared to be setup correctly. I'd like to blame the converter for being a POS, but maybe I did something wrong, who knows. Any one have any thoughts as to what could have happened?
Not phones...but years ago I fried 2 AMD processors because I forgot to plug the fan connector to the motherboard header.
Dumb question, but in addition to the voltage, were you also mindful of the current and ensuring that the power source was outputting no more than 2.0 amps? Sure, a device will only pull the current that it needs in theory, but if you don't have surge protection, then the power spike that may occur as soon as you complete the circuit could fry stuff, especially if the surge is higher than what the device is rated to handle.

This could have been my problem. The power supply I used was rated for 8 amps because I wanted to make sure I had enough power available for my devices on my USB hub (which also got fried in this process). I've already ordered a replacement motherboard for the nexus, but I am sticking to a regular cigarette lighter adapter this time!
Well, in theory it should have been fine unless there was a current spike and the converter couldn't handle it and passed the surge along. But also, was your output voltage set to 5V? A car battery spits out 12.6V or so and while there's usually some wiggle room when it comes to current, there definitely is not when it comes to voltage.
Also, what kind of converter did you use? I'd love to read up on it, just for curiosity's sake.
Sad. It will be OK in a few years. I've been there. We've all been there. It's part of being a true hacker.

As an update, I ended up buying a new motherboard on ebay and switched to a cigarette lighter adapter with a max output of 4 amps. Everything is working great now! Its cool having a tablet in the car.
