Griffin Technology PowerDuo 2 amp Power Charger for iPad, iPhone and iPod (Black)

This item includes a wall plug adapter, a cigarette lighter adapter, and a sync/charging cable that works with various Apple devices (such as the iPad, iPhone, and most iPod models). The advantage to this particular set is that the charging port puts out 2.1 amps, which means that it is designed to charge the iPad at the same rate as the adapter that is packaged with the iPad. Some reviewers on Amazon and elsewhere have reported that it actually charges the iPad slightly faster than the original adapter, and I confirmed with my Kill-a-Watt that the Griffin actually draws about 10% more power from the wall than the stock adapter (see details below). I do not have the tools to accurately check the current draw from the cigarette adapter, but I wouldn't be surprised if it also charges an iPad more quickly.

I have tried several of the USB wall chargers and none have been able to charge my Kindle 2. This one has charged everything I have tried it with. I really like the folding prongs on the wall charger, makes it easier to pack. I also like that this package gives you the ability to charge both in your hotel and in your car, all with the same USB cables.

I travel with a Kindle 2, a Blackberry, and a Ipod Touch. It works with them all. Additionally, one of my friends has the Ipad and I confirmed it does charge the Ipad in a reasonable time frame.

The light is not annoyingly bright like some other USB chargers, but easy to see.

My only wish is that the wall charger had multiple USB ports, but not dividing the current may be why it charges the Kindle.

Finding a decent charger for Apple's newest products is not as simple as you think. All of the products above require newer more powerful chargers and most older ones will not work at all. In addition, the cheap newer copies are hit or miss and you really can mess up your i-product. This Griffin charger works great and charges quickly with no annoying messages popping up on your device. The company is very respectable. The conversion from wall to car is handy for traveling and the cord is long but not too long. . Highly recommended.
