What is Max output in watts?

Max output is the largest amount of power a unit delivers continuously, in watts. It sets the ceiling on what you can run at one moment, while a battery's capacity in watt hours decides how long it lasts. A high figure lets you start a kettle, a heater or a power tool without the supply cutting out. DATOUBOSS states the highest maximum in this group at 12,000 W, against 3,840 W for BLUETTI's home backup and 4,000 W for ALLPOWERS. Match the figure to the biggest appliance you plan to run.
