Why can the car charger and wall charger both charge the BB via the USB port, but the Sync/Charging cable must be plugged into an "active" USB port??
I have an APC laptop bag which plugs into the wall, car, and airplane. It charges my laptop and 2 USB devices. Every other device's Sync/Charging cable has charged the device off of these "power only" ports. Not the BB. . .
If you are a road warrior and haven't seen these bags check them out (they aren't new). They can save you from carrying a TON of different adapters!!www.apc.com
