Hello Marco

Only you can answer your question. Andreas' data sheet states an efficiency of 95%. This means that if you need 95 watts of power, you need 100 watts. How much power do you need now?

Hello Marco

Do you mean the rated power or connected load in watts or standby energy consumption in watt-hours (https://powerwalker.com) [W != Wh -> Power != Energy]

Here is the manufacturer's data sheet with the characteristics : https://powerwalker.com
