GTMax Metalic Black 2-Port USB Car Charger Adapter 2A + Wrist Strap Lanyard

The product states 2A and 1A, each for the ports, but when you have both ports charging, you get only 1.3A and 0.8A.

I have the DROID Bionic, which is notorious for sucking down huge amounts of battery power to do just about anything. Using the 2.1A slot on this charger I can use navigation, play music, and actually have the charge on my battery increase. Typically I use my phone to play music through my car's speakers for my commute home (30-45 min), in that time I can usually go from ~50% up to ~75-80% on the extended battery (normal battery will be full charge in that time). All of the other chargers that I have used w/ this phone will barely keep up w/ the demand of just using navigation, and I would end up "charging" the phone just to stay at the same battery level (or just below).

I have not had any issues that the other reviewers have experienced. I don't know if I lucked out and got one from a good batch, but I am very pleased w/ my purchase.

Product was received quickly and appeared to be a decent item. I bought this for a small road trip so I could charge 2 cell phones at once (HTC Evo and HTC Arrive). The charger took some finagling to keep the led light on so I knew it was getting power, but didn't have any problems with staying on once in place. After just over 2hrs of driving, both phones had less power than when I departed, despite the appearance of charging the entire time. I was the driver and didn't use my phone at all and had the screen off, so I don't know what the cause was, but my Sprint charger doesn't do this at all...

Does not work for my Asus TF300. Plug it in, the red light comes on, doesn't charge the tablet. Tried in 2 different vehicles with a total of 4 power outlets. Also, tried plugging the USB cable into both ports on this adapter. Cannot recommend.

It has two different ports with different amp ratings. I am not sure what was the amp rating that my lumia 900 needed. I tried charging my phone from both ports for a decent drive lasting over 30 minutes (redmond to rattle snake lake). On one port it didn't charge at all. On the other one charging only lasted for some time.

I bought other car charger form AT&T which worked pretty well for me(charge lasts much longer).
