The math

Worked with the typical figure, as the calculator does it.

  1. Output960 W running, so the station's continuous output must be at least 960 W.
  2. SurgeStarting watts are not published, so the surge check uses the 960 W running figure.
  3. Average draw960 W: the running watts count for every hour it is on, as if the motor never paused.
  4. A typical day960 W × 15 min = 240 Wh a day.
  5. Typical 15 min a day960 W × 15 min = 240 Wh usable, ÷ 0.85 = 282 Wh of rated capacity.
  6. 1 hour of use960 W × 1 h = 960 Wh usable, ÷ 0.85 = 1,129 Wh of rated capacity.
  7. On the BLUETTI AC1801,152 Wh × 0.85 = 979 Wh usable, ÷ 960 W = 1.0 h of use.

Stations that run it

Every power station in the data with this appliance alone plugged in, at 85% efficiency. Type the running watts from your own label and the table works it out again.

Add it to the runtime calculator with the rest of your list

What moves the number

Motor size moves the number: 500 W for a corded stick vac to 1,200 W for a full size upright on a 10 amp motor. No start figure is published, so the surge check uses the running watts.

Questions

How many watts does a vacuum cleaner (corded) use?
About 960 W while running, from 500 W to 1,200 W across the models in our sources. Watts vary by model and age. Check the label on your own appliance and enter it for an exact answer.
Can a portable power station run a vacuum cleaner (corded)?
Yes. 44 of the 54 power stations in the Enough Watts data set can power it on its own. It takes at least 960 W of continuous output.
How long will a power station run a vacuum cleaner (corded)?
It depends on the battery. At 85% efficiency the smallest station that powers it, the DJI Power 500 (512 Wh), gives about 27 min of use. The largest, the EcoFlow DELTA Pro Ultra X (12,288 Wh), gives about 10.9 h of use.
Does a vacuum cleaner (corded) need extra watts to start?
Its starting watts are not published, and motors often need 2 to 3 times their running watts to start. Without a published figure the site checks the start at the 960 W running figure, so leave headroom above that on your station.

We read published figures and do the math; we do not measure appliances. The methodology states every formula on this page. Capacities are rated watt hours: 1,000 Wh rated gives 850 Wh usable at the default.
