I compared the technical data to the Griffin PowerJolt and they are not the same, plus the PowerJolt has a fuse.
The PowerJolt & Incase are both certified by Apple, so I am hesitant to purchase anything else. But, the Universal USB is waranteed for life compared to one year.
PowerJolt Specifications:
Input: 12 - 14Vdc
Output: 5.2Vdc;500mA
Maximum Current: 2 Amp
Fuse Type: 2 Amp blade-type mini-auto fuse
Universal USB Specifications:
Input: 12 - 24Vdc
Output: 5.5Vdc;700mA

I use the Griffin iPhone car charger than AT&T sells and have the Incase charger too I find the Griffin is much stronger in construction the Incase feels cheap. but the cord is short on the Griffin
I use the Griffin PowerJolt SE. It's the same as the regular PowerJolt, but it's a direct connection of power, it doesn't go through USB. Plug straight from the cig lighter to the phone.
Great Product. The fact that it has a user-replaceable fuse in case of a surge is a big plus.

I use Griffin Powerjolt but I do agree with ebelp regarding the length of cord. I also use Griffin WindowSeat and the shorter cord makes it difficult to reach to the iPhone when charge is needed.

Does anyone have a Charger with a Line out?? My monster worked for my Ipod and my first gen iphone but the stupid thing doesn't work for the Iphone 3G...it gives me some crap about not being able to charge this device
