Yes — the Explorer 1500 Ultra runs a space heater comfortably

Its 1800W continuous output easily covers the 1500W draw.

Estimated runtime

on a single full charge

Est. usable (AC): 1,175 Wh

Appliance draw: 1500 W

Continuous output: 1800 W

How we calculated this

We start from the Jackery Explorer 1500 Ultra's 1,175 Wh of estimated usable energy at the outlet — its 1,536 Wh rating, derated for a safe depth of discharge and ~15% inverter loss — then divide by the space heater's 1500W draw:

1,175 Wh ÷ 1500 W ≈ 0.8 hours

Heads up: a space heater is a motor/compressor load that spikes 2–3× on startup. The Jackery Explorer 1500 Ultra's 1800W continuous / W surge output should be checked against that startup spike.

Real-world runtime varies with temperature, cable losses, and how hard the appliance actually cycles. Treat this as a solid estimate, not a guarantee.
