(Q) USB Car Chargers - Samsung Epic 4G Touch

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.

[Q] Car charger

I read in a couple posts that existing car chargers can't power the galaxy nexus. i've been using a cheap retractable one i bought from publix for my nexus one for almost a year, and if that one won't charge my Gnex, then i'd like to buy a new one before it comes in.
So does anyone know if theres any truth to what i read, and if so, what chargers are you guys using that works. preferably from amazon
feel bad for bumping this, but i kinda need an answer here.
I use this one. Works great. Its a 2 amp charger.

I don't know the brand of the one I use, but I think you just need to get a USB charger that has a high enough mA output. A standard USB port only puts out 500 mA, which may not be enough to charge the phone while using it. The charger that came with my phone puts out 1000 mA, or 1 Amp. So, I think you just need to look at what the amp your USB charger can provide to see if it will work with your phone. I just got a 2 amp charger with 2 USB ports from Amazon. I haven't had a chance to test it yet, but I expect it will work.
alright so basically try to get a 1000mA or 1Amp+ charger. thanks guys.

Best car charger?

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.

Walgreen's $5 5v 1A usb. Compact and charges like a boss. I've used it for about 3 weeks and I don't have any issues with it. It doesn't heat up my phone at all.

no such thing a rapid charging as the phone draws what it needs.. by "rapid" it just means it supports up to 1A charge rates..

+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.

[Q] New Android Convert From Crapple. Please Help Me Find Chargers!!!

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.

OEM charger output vs. high output car charger

IIRC the stock wall charger is rated at 1.8Ah. But, what is the phone's actual draw? Does it ever get up there near 1.8mAh?
I'm just trying to figure out if a car charger with "only 1000mA" will be sufficient. I'm guessing that the OEM wall charger is rated well above whatever the phone might ask for, but as to how much, I don't know.
I'm actually looking at these two right now as they both seem to give a pretty high output for both Android and Apple devices.

My experience with other phones is that the phone draws exactly what the stock charger gives it. I'd imagine it's the same with this one. 3140mah is a lot of battery to charge.

I'd agree. I charged it the first couple days using the OGP wall charger and USB cable from my Nexus 4. It took all night. Switched the cable with the one in the box, and it charges in like an hour!
I have a 2.1a car charger, and the OGPro charges in exactly the same amount of time as the stock wall charger.
Oddly, it charges slower from my 2a Note II charger.

Im looking at all of the chargers from Anker on Amazon. It seems they have the best positive reviews of anything I've seen. Although the 3.6 watt (white unit with either 2 usb ports or one port and a micro usb cable) unit is newer than the 3.1 (black heavy duty), the black unit can give the full 3.1 watts to either port or split it amongst the two ports. And according to Anker, either port will work for Apple or android. They suggested i get the newer (white) unit, but i want to have the full 3.1 watts available to a single port for future h higher powered devices.
I'll have to check those out. I've been looking at this one, which has good reviews on it.

My concern with that one is that it gives a total of 2.1A. So if you charge your OGP using one usb port, there's only 0.3A left for the other port. The disclaimer at the end of the description says that if you are charging an iPad to not use the second port. I'm guessing that warning would also apply too us with the high draw OGP. It also states that the blue light gets even brighter in the dark. You might need to cover the led if it's too bright,but that's a personal taste thing,and it might not actually be that intrusive. Lastly, do you have enough room in your vehicle to rest both your phone, and the head of the charging device? I have a dual outlet 12v supplier in my car, but i bought one that has no cord. The two outlets are rigidly mounted right at the end of the cigarette lighter plug.
I bought a Griffin Powerjolt single USB at Walmart. It only charges at full speed using the OGPro's stock cable. Any other cable is slower, and the cable from my old S2 gives me a "Slow Charging" notification.
Anyway, this charger is just a stop-gap. I'm going to be hard wiring two USB plugs into my truck's 12v system (with some 5v regulators and an Add-a-Circuit).
I was looking at the 3.6A charger, here's the link on amazon.
As I expected, one port is for Apple and one for Android. This is very irritating because I need to charge my OGP while my fiance charges her OG at the same time on trips.
Can our OGP charge at full speed on the Apple port?
Edit: I just read that the kernal in Android 4.2 fixes this issue so we can charge in any USB charger, including apple chargers. I'm guessing LG devices still on 4.1 won't benefit from this update.
Shouldn't going to Settings > PC Connection > USB Connection Type and then setting it to "Charge only" force the device to see any cable as a charge only cable thus making it charge faster?

As per Anker, the Apple port will charge Android at full speed. I have not verified this myself as I have not gotten mine yet, but that's what I'm told, and expect. I'm waiting for their wall charger to come back in stock as the shipping will be free if l order both.
I ordered the black 3.6v version. I'll get it Monday or Tuesday since I have Prime.
Are there any apps that detect how much juice the battery is getting?

Best wired charger for nexus 5

Hi. Can you guys please tell me which charger you are saying. And which is the best charger for nexus 5 which takes less time to charge up the battery. I recently lost my stock charger and the other chargers I have are taking much longer time to charge the phone they are like 500mAh chargers so its taking long time. Can you guys pleas suggest me the charger.
Check another post in this sub forum. It has links to the BlackBerry playbook chargers, which are awesome and cheap.

I second this - bought a bunch of these chargers to use everywhere.
I'd go with the blackberry folding blade chargers.
There's a review thread someone did. Lots of people here have it. http://forum.xda-developers.com/google-nexus-5/accessories/hands-best-fastest-cheapest-nexus-5-t2729066
It's also so much cheaper than the HP touchpad charger. On amazon you can get anywhere from 4 - 8 chargers for the price of 1 HP.
Just use a USB cable with a MicroUSB port at one end. You always have a computer next to you.

OP was looking for something that can charge faster than 500mA which USB charging is limited to. At that speed it can take 4+ hours to charge the phone vs 2.5 hours with stock, and 2 hours with a 2.1A unit.
My GF got an LG G2 at roughly the same time I got my phone.
I've tried charging my phone with a wide variety of chargers, including the ipad 4 charger, as well as other 2.4A heavy duty chargers from other companies. I dont know why, but NOTHING is as fast as that stock G2 charger. It beats the "heavy duty" voltage stuff by a noticeable margin.
It does a proper quick charge on her G2, and while I've read that the nexus 5 doesnt really support that quick charge, it DEFINITELY does something.
It looks like this: http://www.lg.com/us/images/cell-phone-accessories/wcp-300/gallery/medium05.jpg
I am not sure if you will get the folding blade charger in India. You can buy the CP AD2 charger. One of my friend bought it and the Nexus 5 is charging at around 1300-1400 mAh. You will get it in Amazon for 550 rupees.
