For a refrigerator, the number that matters most is not the headline wattage but the energy the whole system wastes while it waits. The S2000 quotes a 6 watt idle draw and a design Anker says runs a fridge for up to 35 hours, which works out to roughly 57 watts average draw from 2,010 watt-hours. Real figures depend on the fridge, the room temperature and how often the door opens, but the principle holds: a low idle draw gives you more fridge hours per watt-hour.
Its 1,500 watt continuous and 3,000 watt peak are plenty for the compressor start of even a large refrigerator, which typically draws a few hundred watts running and two to three times that for a second at start. It weighs 35.7 pounds, light for 2 kWh, and the rear outlets are positioned so always-on appliances plug into the back. Compared with the Jackery 2000 v2, it matches the capacity but quotes a much longer cell life of 10,000 cycles. Compared with the Anker C1000 Gen 2, it doubles the runtime for a similar footprint class.
There is no 12 volt DC port, and the unit is a bare station with no panel. It supports up to 400 watts of solar and six charging routes, including a generator and a wall outlet. Plan to keep it plugged in as a standby UPS with under 10 millisecond switchover, and let the fridge run through the outage on the battery.
What works
- Six watt idle draw wastes little energy between loads
- Ten thousand cycle LFP cells give a 15 year design life
- Under 10 ms UPS switchover keeps the fridge running through cuts
- Rear outlets keep always-on appliances out of the way
Watch out for
- No 12 V DC port for a car fridge or accessories
- Bare station with no solar panel in the box
- Fifteen hundred watts of output is limited for large extra loads
