The math

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

  1. Output1,200 W running, so the station's continuous output must be at least 1,200 W.
  2. SurgeStarting watts are not published, so the surge check uses the 1,200 W running figure.
  3. Average draw1,200 W: the running watts count for every hour it is on, as if the motor never paused.
  4. A typical day1,200 W × 30 min = 600 Wh a day.
  5. Typical 30 min a day1,200 W × 30 min = 600 Wh usable, ÷ 0.85 = 706 Wh of rated capacity.
  6. 1 hour of use1,200 W × 1 h = 1,200 Wh usable, ÷ 0.85 = 1,412 Wh of rated capacity.
  7. On the Goal Zero Yeti 15001,505 Wh × 0.85 = 1,279 Wh usable, ÷ 1,200 W = 1.1 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

A larger tank usually means a larger motor: 900 W to 1,440 W across the sizes in our sources, the top figure for a 16 gallon vac. No start figure is published, so the surge check uses the running watts.

Questions

How many watts does a wet/dry shop vacuum use?
About 1,200 W while running, from 900 W to 1,440 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 wet/dry shop vacuum?
Yes. 43 of the 54 power stations in the Enough Watts data set can power it on its own. It takes at least 1,200 W of continuous output.
How long will a power station run a wet/dry shop vacuum?
It depends on the battery. At 85% efficiency the smallest station that powers it, the BLUETTI Elite 100 V2 (1,024 Wh), gives about 44 min of use. The largest, the EcoFlow DELTA Pro Ultra X (12,288 Wh), gives about 8.7 h of use.
Does a wet/dry shop vacuum 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 1,200 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.
