I have the Auvio Bluetooth speaker n can't find the charger..where can I order another charger for speaker at??

On the rear of the speaker, you should see a female receptacle, probably the same as your phone. the other end is a usb which would plug into the computer to charge or you can pick up a 5volt wall charger that the usb cable plugs into and the charger plugs into the wall. Any walmart, fry's, radio shack has the readily available.
