Sorry to post slightly off topic... But does anyone know of a USB charger that will actually work with an Android tablet?
I've tried two do far that advertise a power output of 2.1 amps, but tablets won't charge, and upon testing with a voltage meter, I find that they only put out .75 amps.
I ask because Sprint doesn't offer a car charger for the ZTE Optik yet, so I'm on my own!
Any suggestions?

I would try a small power inverter. Then just plug in the wall charger to it.

Google / EBay is USB cable or car charger for a HP touch pad or Blackberry Playbook. Those are the charger I use to charge my E4GT.

Thanks...
All the adapters I see that claim they are compatible with the Touchpad also claim they are compatible with various Android tablets...
Chargers that will charge an iPad2 will NOT provide more than a .5amp charge to an Android tablet, even though they have the same power requirements.
Anything that works for our phones won't provide enough power to charge a tablet.
Its getting rather frustrating.
Hi guys.
I have a problem finding good car charger for my phone while in car.
I either use sygic sat nav or Google maps but on top of that I stream music either via Google music or di.fm app.
Problem starts when I start streaming. My battery slowly drops down about 1% per 15min. I've tried various car chargers that have either 1amp, 2.1 amp and even dual 3.5amp they don't do the job. Only my HTC 1amp charger manages to hold the charge but it doesn't charge on top of that.
Any ideas and suggestions?

I bought the car charger from Amazon HERE earlier this year and it has worked out awesome. I usually leave it in my car but also makes a great wall charger for when you need it in a pinch and didnt bring your own. Its 17 (I got free shipping since I have Amazon Prime) and well worth it since I dont think I ever have to buy another car charger again for any device I own. Even charges my tablet.
Genuine Motorola rapid car charger, simply the best. Charges like a wall charger, seriously, phone says it's plugged into AC power
No other charger I have used, has allowed to use Google navigation and still quickly charge my galaxy nexus

In some roms like Slim ICS you can make the USB charge as fast as a wall charger!
I use a rocketfish 1a charger from bestbuy and it charges while using navigation and streaming.

I use a 1A HTC charger and never had any issues. Are you sure your cigarette lighter is working properly? It sounds like all of these chargers you've tried are charging at less than 1A.
I think 1 amp is about all it will do. It will have a hard time keeping up if you are using it a lot. I have the htc car charger and it seems to keep up for me but actually getting a decent charge while using it will be hard.

not all 1a chargers actually charge at 1a. it depends on if the two middle pins are shorted together or not.
this charger is cheap as hell - 3 bucks - and charges at a full 1a. i use it and it works perfectly.

I noticed this too, using a Kensington USB charger in the car. On my drive out to Phoenix, I noticed that having Navigation running while plugged in caused the battery to drain.
I also noticed that running Torque sucks the battery down as well. I stopped at a gas station that had a ton of gadgets, so I bought another off-brand USB adapter that stated its output is 1.5A. I also picked up the OEM extended battery at a VZW store while out there. It doesn't drain as fast now, but it does still drain a bit.

Absolutely go for the motorola charger. I use it everytime in car, it's a 1A charger, has a nice blue light and can charge your phone even when using navigation.
And on top of that it's also cheap. I bought it in boundle with a motorola wall charger @ 10€.
is it this one guys http://www.ebay.com/itm/OEM-Motorol...846874?pt=PDA_Accessories&hash=item2a1ea6619a
Make shift cable.
If you're super cheap and/or like to DIY, I was able to get my Galaxy Nexus to recognize any USB charger as AC by cutting a USB extension cable in half. I then soldered/twisted the green and white wires within the USB cable together and then I soldered the red to red and black to black. By putting the modified USB extension in between the charger and a USB to Micro USB cable it will force the phone to recognize the charger as AC instead of USB. I sealed up my adapter with some White and Green heat-shrink tubing I had lying around so it would be easy to identify. Same thing can be done to a USB to Micro-USB cable if you want.

For anyone still interested in the Motorola Rapid Charger, Amazon has it a few bucks cheaper than the ebay ad posted earlier.

Anyone in Canada interested in getting one of these for $5 + CDN shipping? I just picked up 4 of these from my mailbox in the states and am selling 3. PM me if you're game. (BTW, charges my GNex in AC mode) And if you're in Vancouver you can pick it up in person
So which car charger do you guys recommend for the S3 that has AC charging enabled?

rapid charger at up to 1A. best car charger on the market, especially for the price.
Does anyone know where to get a USB coil cord that would fit into this?
Personally I have the wireless charging mod done and in my car use a Palm Pre Touchstone as a charger. It looks incredibly good and clean.
It is NOT the fastest charger however (only about 500mah charge rate).
If you want the fastest charging, I would get one of the ipad car chargers. 2.1 amps of charge power will more than juice your phone.
Personally, I recommend the Griffin one: http://www.ebay.com/itm/GRIFFIN-POW...ccessories&hash=item3a779d867b#ht_2277wt_1166
You may be able to find it cheaper somewhere.
I've read in a few places that rapid charging isn't good for our batteries. Any truth to that?
The phone will only take 1 amp regardless of the charger being 2 amps. Buy a well built one and you'll be fine, they all charge the same provided they are 1 amp.

+1 for this, I've been using this for ALL of my Android phones.
A lot of people seem to recommend that Motorola charger in these forums for various devices. I think I'm going to order one.
The Moto car charger has decent reviews on Amazon.
There any others recommendations of car chargers ?
Be careful. Bought a cheap one and found it sent dirty power that introduced noise into the audio out on my car dock.
I cant find the link but there is a 3 amp chager in the tmobile store its expensive but worth it.. a 15 minute drive gave me a 23% boost

I bought that bad boy. The build quality is awesome. You can twist off the cap and replace the fuse if it's blown. Unlike some other chargers you have to pry it out and possibly break it. This one can charge up to 3.1 amp on one usb port for tablets and 1.0 amp on the other port cell phones. Yes by default my phone was charging in AC mode with my sam captivate. Then i decided to modify it from one of users tip on there for permanent AC charging. No issues so far.
I just ordered a Griffin PowerJolt. I hope I get one of the newer ones that work with ac mode.
I use the USB port in my deck.

What is the AC mode you are speaking of?
I don't recall the exact part number, but its the oem HTC kit I got for my One S prior to trading it in. Nothing fancy, but high quality and power, and the S3 doesn't seem to be picky.

How do you stop the deck from trying to index the whole phone? That is the problem I've had when trying that in the past. Is their a setting somewhere, or a cable mod that allows charging but no data?
I use the I-GO, bought it at Radio Shack in I think 2004, been able to charge any phone I've had since then all you have to do is buy the little adapter for each phone, just got one for my GSII for 7 bucks after changing from an IPhone.
Using the t mobile branded mini usb chadger that i got with moto razr. I added a mini to micro usb adapter.

Some cheapo usb adapters do not charge at full power. They charge as if they are plugged into a computer (500ma)
It is because the factory forgets to short the datapins.

When I plug my phone in its charge only. Only when I go to "USB mode" dose it index the phone.

I did a lot of research and came up with the following. Been using it for a week now and it charges fast. I did short out the two center usb pins. This is a true 3.1 amp charger. It does not split the power to charge two devices like most 2 amp chargers do. One plug is 1 amp and the other is 2.1 amp.

So no matter where I look, I cannot find good chargers for my GN2. Here I was thinking that I'd be able to use my 10+ white brick crapple charging blocks at 1A and here my awesome GN2 uses a 2A.
Now I understand that Apple swayed away from yet another standard and the pins need to be shorted in almost all car chargers in order for anything other than an apple device to accept an AC charge. Awesome.
I'm very happy that this huge battery needs a 2A charger but I'm back at square one. I need chargers... I need a lot. Please somebody point me in the right direction on what every android peep is doing to charge their phones on fast chargers... I am mostly in need of a car charger. Every forum I look at, the thread ends with no definitive answer...
Much thanks.

This is the charger that I use for my car charging needs. Ive had it for a couple if years and it has worked flawlessly. It also has an extra usb port for charging a 2nd device. I havent had any quality issues with mine like some of the reviewers have claimed. This works brilliantly with my Note 2. It can output up to 4 amps and charges 2 Note 2's with max screen brightness and GPS with no problem.
