About
Power-station listings quote watt-hours. Buyers need hours: how long the fridge, the CPAP or the router will keep running. RuntimeMath turns the makers’ published specs into those hours and shows the math. It is run by Kristoffer Myklebust (Kristoffer Myklebust ENK, Norway).
- Specs come from makers’ US pages and manuals; where a figure is missing there, the station page says which other source we used. Prices are read from makers’ US stores and dated. We don’t test products.
- Every formula is on How we calculate. Commissions never change the results.
