Best Automatic Transfer Switches for RVs in 2025

Choosing the right automatic transfer switch (ATS) is one of the most important decisions you'll make when upgrading your RV's electrical system. An ATS automatically switches your RV's power source between shore power and your generator, eliminating the need to manually plug and unplug cords. This not only adds convenience but also protects your electrical components from dangerous backfeeding and voltage spikes. In 2025, the market offers more options than ever, from budget-friendly models to advanced units with surge protection and remote monitoring. Below, we've rounded up the 7 best automatic transfer switches for RVs in 2025, based on performance, reliability, and value.
