About GeneratorChecker

What We Do

GeneratorChecker is an independent engineering resource that helps consumers determine whether a portable power station can safely run their household devices. We analyze compatibility across fridges, air conditioners, CPAP machines, sump pumps, power tools, and dozens of other common appliances.

Every recommendation on this site is based on published manufacturer specifications, not guesswork. We cross-reference OEM user manuals, spec sheets, NEC electrical tables, and government databases to deliver accurate, transparent results.

Why This Exists

Most "wattage charts" published by generator brands and retail sites are dangerously oversimplified. They list running watts but ignore surge requirements, compressor startup loads, and voltage constraints. A chart might say a 1,000W station can run a fridge when in reality, the compressor surge alone could exceed 2,000W.

GeneratorChecker was built to fix this. Our compatibility engine accounts for running watts, surge watts, voltage requirements, buffer margins by load profile, and soft-start eligibility. When we say a power station can run your device, the math supports it.

Our Data Standards

We maintain strict sourcing standards for every data point on this site:

• OEM Manuals and Spec Sheets are our primary source for device wattage, amperage, and surge ratings.
• NEC Tables (430.248, 430.7B) are used for motor surge estimation when manufacturer LRA data is unavailable.
• Government Databases including ENERGY STAR, DOE CCMS, and AHRI provide cross-validation for appliance efficiency ratings.
• Engineering Estimates are clearly labeled as such and never presented as verified data.

Independence and Revenue

GeneratorChecker earns revenue through affiliate partnerships with Amazon and manufacturer websites. When you purchase a product through one of our links, we may earn a small commission at no extra cost to you.

Affiliate relationships do not influence our compatibility ratings, verdicts, or recommendations. Our analysis is driven entirely by electrical specifications and engineering calculations. A power station either meets the requirements or it does not.
