About Genius Harbor
Genius Harbor helps RV owners choose the gear that keeps campground power from hurting their rig. We write for weekend campers, snowbirds and full-timers alike.
Our guides use plain words. When a term matters, like EMS, open ground or pure sine wave, we explain what it means for you at the pedestal.
What we cover
We cover RV surge protectors and EMS units, both portable and hardwired, for 30 and 50 amp rigs. We compare brands like Progressive Industries, Power Watchdog and Southwire Surge Guard.
We also cover the rest of the power setup: extension cords and adapters, soft starts, LiFePO4 house batteries, inverters, converter chargers and roof solar. We add new guides over time.
How we work
We read the specs, the maker's details and the manuals for the gear we cover. We also read what owners report after a season or more on the road.
Then we sort it all by your amp service, your rig and how you camp. Our How we research page explains each step.
What we are not
We don't make, sell or install power gear. No maker pays us to rank its products.
Genius Harbor is an independent buying-guide site. We aren't linked to Progressive Industries, Hughes Autoformers, Southwire or any other brand we write about.
We don't claim to have used every unit ourselves. When we pick one, we say why, based on its specs, its features and owner feedback.
We don't give wiring steps. Hardwired units, inverters and battery banks are work for a qualified RV technician or a licensed electrician.
How the site earns money
Some links on this site go to stores like Amazon. If you buy through one, we may earn a small commission at no extra cost to you.
That never decides which products we pick. Our affiliate disclosure has the details.
