How long will a Zendure SuperBase V6400 run LED Christmas tree lights (500 bulbs)?
About 3.2 days — 3 days 6 h typically, from 3 days 1 h in the worst case to 3 days 10 h at best. That assumes LED Christmas tree lights (500 bulbs) pulling 35 W continuously, plus the station's 22 W AC mains socket overhead — 57 W in total out of 4,433 usable watt-hours.
Note how much of that draw is the station rather than the appliance: 39% of the energy goes on keeping the inverter awake. On a load this small, the idle draw matters more than the capacity does.
