Buying Guide

Match amperage and connector type

Confirm the adapter converts between the exact shore power connectors you need (30A↔50A, 50A↔15A, TT-30R, etc.) to avoid incompatible plugs or unsafe setups

Prioritize surge and overload protection

Models with built-in surge suppression (measured in joules) and automatic overload cutoff protect RV electronics and are preferable for campgrounds with variable power

Check certification and testing

Look for third-party safety marks such as ETL or equivalent to ensure the adapter meets electrical safety standards for continuous RV use

Consider cable length and flexibility

Short, robust cords reduce voltage drop and clutter near the pedestal; choose a length that keeps connections secure without excessive strain

Mind vehicle power compatibility

For powering specific devices like Starlink from a vehicle, select an adapter rated for the vehicle’s 12V–24V system and designed for that accessory’s power profile
