POWERING A 12V DC DEVICE6.
The Portable Power 1150 is a power source for all 12 volt DC accessories
that are equipped with a 12V accessory plug. The DC accessory outlet
has a 15-amp automatic overload protection circuit breaker. The breaker
will automatically reset after an overload occurs.

Portable Power 1150.
Plug the 12V DC device into the DC power outlet, and turn the 12V DC •
device “ON” (if required).
If the 12V DC device draws more than 15A, the internal circuit breaker •
