What it runs
It powers 11 of the 16 common appliances below, each on its own. A modern full size refrigerator runs about 4.5 h on a full charge. It cannot power a sump pump (1/2 HP). Needs 925 W running at once; this station gives 600 W. It also cannot power 4 more from the list.

Running time is usable watt hours divided by the appliance's average draw, with nothing else plugged in. Loads used for minutes a day show minutes of use. Watts vary by model and age. Check the label on your own appliance and enter it for an exact answer.

Recharging
From the wall
Maximum AC charging input: 380 W.
The maker states these wall charging times:
- 0 to 100% in 1 h
From solar
It takes up to 220 W of solar. Worked at 4 peak sun hours, counting 75% of the panel rating to allow for heat, angle and controller losses:
- 200 W of panels × 4 h of sun × 0.75 = 600 Wh a day. From empty to full: 286 ÷ (200 × 0.75) = 1.9 hours of sun.
- 220 W of panels × 4 h of sun × 0.75 = 660 Wh a day. From empty to full: 286 ÷ (220 × 0.75) = 1.7 hours of sun.

Expansion and backup mode
It takes expansion batteries (RIVER 3 Plus Smart Extra Battery (EB300 or EB600)) up to 858 Wh in total: 729 Wh usable (858 × 0.85).
Backup (UPS) mode: the maker states a switchover of 20 ms or faster.
X-Boost can run this at up to 1,200 W by lowering the voltage. That suits heaters and kettles, not motors or electronics. The verdicts on this site never count it as output.
