Sourced and dated: every number links to an official source.
We started WattHourLab because power station spec sheets are confusing: watt-hours, surge watts and cycle ratings rarely line up from one brand to the next. So we work out backup power from the official numbers, link every source, and lay it out plainly so you can plan with peace of mind.
