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.

For medical equipment, confirm the power needs with the device maker and keep a backup plan. This page is not medical advice.

Recharging

From the wall

Maximum AC charging input: 1,800 W.

From solar

It takes up to 2,400 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: 2,764.8 ÷ (200 × 0.75) = 18.4 hours of sun.
  • 2,400 W of panels × 4 h of sun × 0.75 = 7,200 Wh a day. From empty to full: 2,764.8 ÷ (2,400 × 0.75) = 1.5 hours of sun.

Car charging input: not published.

Expansion and backup mode

It takes expansion batteries (B300K, B500K, B300S, B300) up to 21,197 Wh in total: 18,017 Wh usable (21,196.8 × 0.85).

Backup (UPS) mode: its UPS outlets pass power straight through, so there is no switchover gap.

Lifting Power can run this at up to 7,680 W by lowering the voltage. That suits heaters and kettles, not motors or electronics. The verdicts on this site never count it as output.

It supplies 240 V split phase on its own.
