Common questions
How long will the Anker SOLIX S5000 run a full-size fridge?
About 2.8 days on a full charge, using our planning figures (85% of rated capacity usable, fridge at 1,500Wh per day). Real runtime depends on the fridge’s duty cycle and ambient temperature.
How many nights will it run a CPAP?
About 8.9 nights at 480Wh per night (60W for 8 hours, humidifier on). Turning the humidifier and heated tube off stretches that considerably.
Can its capacity be expanded?
Yes — with the manufacturer’s extra batteries it grows from 5,024Wh to 30,000Wh.
Does it work as a UPS?
Its published switchover is ≤ 10 ms, fast enough for most electronics to ride through an outage without rebooting.
