What size power station for a vacuum cleaner (corded)?
It needs a station with at least 960 W of continuous output (starting watts not published, so the check uses running watts). At the default 85% efficiency it takes about 282 Wh of rated capacity for its typical 15 min a day, and 1,129 Wh for 1 hour of use. 44 of the 54 power stations in the Enough Watts data set can power it. The smallest one that keeps it going for 1 hour of use is the BLUETTI AC180 (1,152 Wh).

Watts
Typical figures for this type, from the sources at the foot of this page. Watts vary by model and age. Check the label on your own appliance and enter it for an exact answer.
- Running, typical
- 960 W
- Running, low to high
- 500 W to 1,200 W
- Starting
- Not publishedmotors often need 2 to 3 times their running watts to start
- Typical use a day
- 15 minhours the motor actually runs
- Average draw while on
- 960 W
- Voltage
- 120 V
- Assumes the motor runs the whole time; real use is often less.
- Starting watts not published; motors often need 2 to 3 times their running watts to start.

The math
Worked with the typical figure, as the calculator does it.
- Output960 W running, so the station's continuous output must be at least 960 W.
- SurgeStarting watts are not published, so the surge check uses the 960 W running figure.
- Average draw960 W: the running watts count for every hour it is on, as if the motor never paused.
- A typical day960 W × 15 min = 240 Wh a day.
- Typical 15 min a day960 W × 15 min = 240 Wh usable, ÷ 0.85 = 282 Wh of rated capacity.
- 1 hour of use960 W × 1 h = 960 Wh usable, ÷ 0.85 = 1,129 Wh of rated capacity.
- 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.
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.

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.
