About WattSheet
WattSheet exists because power station marketing is confusing: "3600W" might be a surge rating, "1-hour charging" might need an extra accessory, and capacity numbers rarely tell you how long your fridge will actually run.
We put every major model on one spec sheet, normalize the numbers, and do the runtime math for you. Rankings are computed from the data, not from who pays the highest commission.
Spot a wrong spec? We check manufacturer spec sheets regularly, but brands revise models often — corrections are always welcome.
WattSheet is part of BuyerSheet, a small family of independent comparison sites that rank products on the numbers.
