Anyone else pick up one of these? It claims to put out up to 2.1 amps of current, its primarily for the iPad, but Griffin says its perfectly OK for iPhones and iPods. I bought it for my iPhone 3G because the 1 amp charger I was using could not keep the battery from draining while using a data based GPS navigation system. Supposedly the iPhone will draw as much as it needs from the power source, so with a lot more current, it should be an ideal solution.
So here's the thing and I don't have this issue with any other charger, while it's plugged into the iPhone, the phone's battery percentage (via iOS 4 or SBSettings when jb'd) does not change. At all. It sticks on whatever charge capacity it was showing when first plugged in. I either have to plug in a different power source or reboot it to register the change. When doing this you can see that the battery has been charging all along, just not able to show the increase. My thought is that the iPhone battery management system (I'm using iOS 4 and jb'd) gets dizzy with the high current and just punts.
This is all a bit troubling. When I plug my "inferior" (ha!) HTC Fuze into the same charger and use tBattery to show current draw from the "PowerJolt for iPad", it uses about the same as my 1 amp charger, around 680 milliamps (my guess is the Fuze regulates to this amount). This does confirm that there is nothing wrong with the charger itself. It's the iPhone that's borked.
The big issue is, am I harming my 3G with this thing? I'm waiting to hear Griffin's response to all this and I'll report what they say.
