Why does the Jackery Explorer 1000 v2 run a space heater for so little time?

Because it draws a lot of power. A space heater averages about 750 W (1,500 W running, on about 50% of the time), and the 1,070 Wh battery gives about 910 Wh after inverter losses. That is 82% of the battery an hour.

What would run a space heater longer?

A bigger battery: the 2,042 Wh Jackery Explorer 2000 v2 about 2.5 hours and the 2,048 Wh Anker SOLIX C2000 Gen 2 about 2.5 hours.

Can the Jackery Explorer 1000 v2 run a space heater (1500W)?

Published October 12, 2026

Short answerYes, briefly

Yes, but only for about 1 hour. A space heater averages about 750 W, and the Jackery Explorer 1000 v2 holds 1,070 Wh (about 910 Wh usable after inverter losses), so the battery runs down fast. Fine for a short job, not for a whole day.
