Generators list two numbers. Running (or rated) watts is what it can supply continuously. Starting (surge, peak or maximum) watts is the short burst it can give while a motor starts. The big number on the box is usually the starting figure. Across the 11 generators we track, running watts are 80% of starting watts on average.
Power stations list capacity in watt-hours (how much energy is stored), continuous output in watts, and sometimes surge watts. If the surge isn’t published we say we can’t confirm a motor will start, instead of guessing.
