Keyspan USB to Cell Phone Charger

Keyspan : ZIP-LINQ USB Cell Phone Charger Cable - Ericsson
I ordered one of these late last week. It arrived today. It works pretty well. Basically, the zip thing is a regular USB cable. The kit comes with a USB to Ericsson phone power adapter. That way I don't have to bring along the cell charger when I'm on the road. In some ways, this is a pointless accessory because a phone charge lasts three to four days. Trips lasting longer than that typically require a hotel with powersource, etc. However, whenever I run Bluetooth on the phone, the battery lasts for a day or a day and a half. With this smaller than charger gizmo in my bag, I can keep the phone topped off and keep Bluetooth on all the time. For me, that's the cool part.
