Can a Bluetti AC50B run a space heater (1500 w)?

No — the Bluetti AC50B can't run a space heater (1500 w).
The space heater (1500 w) draws about 1,500 W (a steady resistive load); the AC50B delivers 700 W continuous and 1,000 W surge. That's not enough continuous output.

Common questions

Can the Bluetti AC50B run a space heater (1500 w)?

No. A space heater (1500 w) needs 1,500 W continuous and a 1,500 W startup surge, but the Bluetti AC50B only delivers 700 W continuous and a 1,000 W surge — so it can’t sustain the running load. You'd want a larger unit.
