Average Reviews:
(More customer reviews)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.
STOCK iPad ADAPTER:
When first plugged in: 11W
After a few seconds: 10W
Above 80% charge: 9W
GRIFFIN POWERBLOCK WALL CHARGER:
When first plugged in: 12W
After a few seconds: 11W
Above 80% charge: 10W
The cable packaged with the Griffin chargers works not only as a charging cable, but as a sync cable as well; i.e. you can use it to connect your Apple device and your computer to sync data between them. If you have an iPad, it WILL charge as well--although the iPad screen will probably say "Not charging" and the charge rate will be much slower (.5A from most USB ports, compared to 2.1A from the wall or cigarette lighter).
The Griffin chargers are light but seem well built. The wall charger, although longer than the stock iPad charger, is only slightly thicker but not as wide (see my customer image), and it also has a folding plug. So it has a nice form factor that is just as convenient for travel as the original adapter.
This set is also available at the Apple store, so obviously Apple endorses this set of Griffin chargers for their own products. However, it is considerably cheaper here on Amazon.
