Buying Guide

Match amperage to your RV

Choose 30A or 50A surge protection and cords to match your RV’s pedestal connection and service panel to avoid overloads

Prioritize surge and EMS features

Look for surge protectors with built-in electrical management system (EMS) or smart-surge diagnostics to detect wiring faults and unsafe conditions

Check battery monitoring options

Select a shunt-based battery monitor with a clear display if you need real-time state-of-charge, voltage, and current tracking for house batteries

Consider LiFePO4 with integrated BMS

For longer life and safer cycling, choose LiFePO4 batteries that include a built-in battery management system (BMS) sized for your load profile

Balance portability and durability

Portable surge protectors are convenient for travel; heavy-duty weatherproof enclosures and robust plugs improve longevity at campgrounds
