Customer Reviews

Great iPhone 3G charger. USB is the way to go!
Problem: The 3g iPhone drains your battery like no other. If you're on a road trip or if you use the GPS extensively, you're going to need a car charger.

What we were looking for: I've read too many horror stories of third party chargers bricking iPhones. So I wanted something reliable. I looked for items they sold at the apple store here on Amazon, as it is much cheaper here. I figured if Apple was selling them, they must be more reliable than these other cheaper alternatives that have been damaging phones.

Pros:
1. USB! I think this will be the trend for chargers. More and more chargers will be USB cords, so you won't have to get a billion tips for your different devices. You just plug in the USB cord that came with your product in the first place. This is a 5.5 V system, so both my iPhone and my Jawbone work.
2. Fuse: I like that it has a fuse. Its very reassuring after reading how many iPhones have been messed up by third party chargers.
3. Dual USB on the powerblock (AC home wall adapter not cigarettelighter). You can charge 2 usb devices at once. Note that the powerjolt (cigarette lighter adapter) only has 1 usb port. I've read that other car adapters that incorporate 2 usb ports hum annoyingly.
4. Small car adapter unit: barely sticks out.

Cons:
1. The powerblock is a bit bulky. I was planning on taking this with me on trips, but I think I'll take the iPhone charger instead and leave this one at home.

Conclusion: Great car charger for the 3g iPhone, with a fuse for assurance. The powerblock unit has 2 usb devices allowing you to charge 2 usb devices at once. Just use your usb cable, no more annoying car charger adapter tips to deal with.

Works as advertised.
I bought this for the dual wall adaptor but I incorrectly assumed the DC Car adaptor was dual as well. The car adaptor only charges one item at a time.

Works Well
Overall, this is a great product, or two products. Unlike most other iPhone/iPod chargers, this requires you to provide your own USB to dock connector cable(s). But, I have several of these that I've accumulated over the years, so it's not a problem for me. Plus, I like that I can power/charge other USB devices, like my Garmin GPSMAP 60CSx 2.6-Inch Mapping Handheld GPS (for use in the car) and my Jawbone Bluetooth Headset with NoiseAssassin-Black (Jawbone II). I like how the ring around the car charger glows different colors depending on whether the iPod is charging or fully charged. This is also the first car charger I've seen with a changeable fuse, in case it's necessary. My only complaint is that Griffin could have put two USB ports in the car charger so both units could charge two devices (I have seen some other solutions that include two USB ports, like the Scosche USB12V2 Dual USB Car Charger).
