Bluetooth USB Dongle

RFQ Details

I am looking for a dongle with Bluetooth 2.0 (preferably bluetooth -host), large flash memory and USB connector, which has either an internal battery or it can connect to another power source than a PC or PDA. The idea is to collect data over Bluetooth to the stick and then later on discharge this data to a PC over USB -connector, which would also charge the internal battery (if available). In the optimal case it has also a key ring.
