Yes. SPOT Trace can be line powered through a 5v USB connection. For use on a car, motorcycle, or mid-sized boat, a common 12v adapter would work. A marine rated model is recommended for use on a boat. These adapters can be purchased wherever electronics are sold. For smaller boats that only have a 12v battery and no plug-in option, we recommend a straight battery to USB adapter.
Using USB line power will NOT charge the batteries inside the unit and Spot Trace is NOT waterproof when connected to line power unless using a waterproof USB cable (not included in packaging).
