I misplaced my 12V to 5V cigarette lighter adapter for my F500BT.

I got a new car and don't have room and can't be bothered installing the gateway amp. Currently I am driving around with the amp sitting loosely in a compartment.

 

Where would I get a replacement adapter, or can I just get a random one that's rated for adequate current (which I understand is 3A)?

I tried a USB charge that was rated at 1.5A and that made the device reboot rapidly.

 

Thanks,
