Affiliate Disclosure

This calculator is free to use. We keep it that way, in part, through affiliate relationships with generator, portable power station, and battery manufacturers and retailers. If you click through to a product and buy it, we may earn a commission at no extra cost to you.

Technical fit is evaluated before commission

Our process is designed so that a product cannot be recommended unless it can actually handle the load you told us about — continuous output, startup surge, and required battery capacity are checked first. Commercial terms are only ever used to rank between products that already pass that check. We can't claim complete independence from commercial incentives — we do earn commissions — but we do not recommend a product we believe is underpowered for your stated needs in order to earn one.

What this doesn't mean

If nothing in our catalog is a good technical fit for what you described, we'll say so rather than pointing you to the closest available product anyway.
