Nowadays, RVs have all kinds of sophisticated electronics onboard. Microwaves, televisions, refrigerators, cell phones and computers all run off of your RVs power source, and all are at risk of high or low voltage and a power surge or spike. Repairing and replacing RV appliances and accessories can be costly, especially if they all become affected at once. Protect your RV and appliances from high or low voltage levels and surges with Camco's PowerGrip Voltage Protector and Circuit Analyzer. The Camco PowerGrip Voltage Protector and Circuit Analyzer protects from high voltage, surges such as lightening and low voltage which can be equally harmful.
