How Long Will It Run

How long will a Zendure SuperBase V6400 run a garden inflatable (christmas or halloween)?

About 2.6 days — 2 days 14 h typically, from 2 days 10 h in the worst case to 2 days 17 h at best. That assumes a garden inflatable (christmas or halloween) pulling 50 W continuously, plus the station's 22 W AC mains socket overhead — 72 W in total out of 4,433 usable watt-hours.

Note how much of that draw is the station rather than the appliance: 31% of the energy goes on keeping the inverter awake. On a load this small, the idle draw matters more than the capacity does.

  • 7.7 nights of eight hours, or 2.57 days of continuous running.
  • Usable energy: 4,433 Wh of the 6,438 Wh on the box, after chemistry, inverter losses and the reserve.
  • To keep it going for a full 24 hours you would need about 2,378 Wh of rated capacity — which this station has.
  • Start-up: the garden inflatable (christmas or halloween) asks for 50 W at switch-on against this station's 7,600 W peak — comfortable.
