I bought
these 6 ft. cables and they work great. Delivery time for me was 4 days.
My testing with chargers is that any rated 700 mA or higher will work (the Moto wall plug is 850 mA). I have both an LG and a Blackberry charger that are rated 700 mA and they both work fine. I have a Moto charger rated at 550 mA and it will not charge the phone (it is for a Bluetooth earpiece).
I have not found any of the 12v usb adapters (that plug into a cigarette lighter) that work to charge the BF. I have tried three. Two were rated at 1 amp, but they were also rated for 12-24 volts input. So at 12v they probably put out 500 mA, which is not enough.
