The Quantum RA0 Adapter may be used to connect the Quantum Battery 5 or Battery 5+ to many types of communication (and other) equipment that operate on 12 VDC. The maximum continuous drain must be 3A or less. An automatic circuit breaker will open at higher currents.
The RA0 can be used to wire an empty battery case, DC power plug or be hard wired to your equipment.
