Haier 2-Piece Micro-Mini DC Car Charger for iPad iPhone Android Mobile Devices $7

Probably no way this can charge a TF101 eh? Would be awesome if it'd work with my S3, and Transformer.

isn't this a better deal?

How many amps does the Transformer need? This charger outputs 3.1A, so it should be good for a phone(~.5-1A) and most tablets(~2.1A):

There's a 2 for 1 deal with this promo code as well: 1N13NT88
There's also a few other promos listed on the page if you don't want two chargers.

Getting this for charging my ipod in the car & the bonus that it can double as my phone charger if I need to. Thanks OP

Quote from inspyral : Besides the fact that it only has one USB port, I don't think 2.1A is going to be enough to charge both a phone and a tablet at the same time. I think the S3 uses a 1A charger, and most tablets use 2-2.1A, so if you were to somehow connect both to this device they would charge much slower than normal, if at all. You'd want something with around 3A(and two ports) to reliably charge a phone and tablet simultaneously. Something like this should satisfy your needs: http://www.amazon.com/high-speed-...009HD44US/ There was a 2 for 1 promo for it a while back, but the regular price is pretty decent if you have Prime or are ordering other stuff. Edit: Actually it looks like the 2 for 1 promo is still good, so if you you can get two 3.1A dual port chargers for $10.95.

Review said the amazon deal ..charger says its only 10 watt 2amp

and this is "slick" why?

oh, must be b/c Selma posted it

Apparently that seems to be an issue of mislabeling or a different product:

However, another review said modifications are needed to get your device to charge in AC mode rather than USB mode(which is limited to something like 500mA). I actually hadn't known about the difference between AC and USB charging modes, so I did some testing with the two external batteries and cheap car charger I have.

For my phone, both of the external batteries I have (a VAAS 5000mAh 2.1/1A unit, and a cheap 1.5A unit that claims 4400mAh from eBay) would only charge in USB mode, while the generic 1A car charger I have charged in AC mode. I then tried the same test with my tablet and was a little surprised by the results - everything was able to charge it in AC mode. The only exception was connecting it to my desktop PC, which engaged USB charging, although that may be because it connects as a media device for data transfer. I actually tried to cancel my order after I read some of the reviews, but it was already marked "shipping soon" so it looks like I'm stuck. I'll try the same test when they arrive if I don't end up refusing the shipment.

As the resident charging expert i will Explain a few things about chargers and high current charging mode:

Industry standards are: to enable high current charging you need to have the 2 data lines shorted together. This tells the tablet/phone its not plugged into a usb port(500ma limit).

However no one goes by standards. So there trick is they put a voltage divider on the shorted data pins from the 5v/ground connections so that there is 2-4v on the data lines. This way you have to use their charger.

So what i do is mod the "standard" chargers with 2 resistors of equal value and pop them inbetween the data lines and 5v/ground. so they sit at 2.5v, which is good enough for all devices.

As for the 2amp thing. A dead tablet will suck 2amp till its 20% charged(15min tops), then it sucks 1.5amps, by 50% charge its down to 1amp, by 75% you are lucky to be sucking 200ma. This is a linear graph, i just noted some points.

In other news my favorite charger is the tmobile premium 3amp model with 2 usb slots. Its got the blank pads for the 2.5v mod on the datalines already so its real easy to mod.

For anyone wondering about the New Trent dual 1/2.1A 15W charger I linked above [amazon.com], I got mine in today and did some informal testing. I used my phone (Samsung Galaxy Nexus), tablet (Nexus 7), and OEM/generic micro USB cables. My phone would only charge in USB mode, regardless of the port or cable used, while my tablet charged in AC mode with the OEM cables(both Samsung and ASUS) on both ports, but would only charge in USB mode with the generic cable included with the charger. The tablet results were somewhat expected, but it was strange that my phone wouldn't charge in AC mode with this charger when it did so with the generic one I've been using. I wanted to monitor the actual current, but none of the battery monitoring apps I tried worked with either my phone or tablet for displaying mA/A.

out of stock

Got one.. thanks OP.

How is the quality on these? Are these durable? (and don't feel cheap?)

For $7.99, this is cheap for both a car and wall charger combo outputting 2.1A.

Thanks OP!

If you need two low-power chargers from one car outlet, maybe so.

Quote from RugerRedhawk : Am I missing something? Can't you get a USB car charger for $2 any day now and use whatever cables you want?

In iLanguage, this can charge iPads at 2.1 amps, and iPhones at 1 amp, instead of the standard, low (normal) power of 0.5 amp.

Apparently this charger's abilities is recognized by the iDevice, so the iDevice can determine that it can draw 1 or 2 amps. If the charger isn't recognized, the iDevice may draw 0.5 amps, or maybe none.
