Need to run it alongside other things? Add it to the full sizing tool with the rest of your load.

What size you need for 8.0 h

You need about 444 Wh — and 41 units fit. The smallest sufficient is the Bluetti AC50B; we never push more capacity than your load can use. Surge to clear: 100 W.

The math
Running watts (everything on at once) = 100 W
Surge watts (worst single startup + the rest running) = 100 W
Average draw (cyclic loads counted by their duty cycle) = 50 W
Watt-hours = 50 W × 8.0 h ÷ 90% usable reserve = 444 Wh

Common questions

What size power station do I need to run an electric blanket?

An electric blanket draws about 100 W running (a resistive load, so no real startup surge). So you want a unit with at least 100 W continuous output. For 8.0 h of runtime that's roughly 444 Wh of capacity — the Bluetti AC50B is the smallest unit that clears all of it.

How many watts does an electric blanket use?

About 100 W while running. It only draws power about 50% of the time, so over an outage its energy use is well below 100 W × the hours — which is why a modest battery lasts longer than you'd expect.
