What size power station for a dehumidifier (35 pint)?

It needs a station with at least 351 W of continuous output (starting watts not published, so the check uses running watts). At the default 85% efficiency it takes about 3,304 Wh of rated capacity for 8 hours of running, and 9,911 Wh for 24 hours of running. 50 of the 54 power stations in the Enough Watts data set can power it. The smallest one that keeps it going for 24 hours of running is the EcoFlow DELTA Pro Ultra X (12,288 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: 351 W
Running, low to high: 342 W to 358 W
Starting: Not publishedmotors often need 2 to 3 times their running watts to start
Typical use a day: 12 hhours the motor actually runs
Average draw while on: 351 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.

Output351 W running, so the station's continuous output must be at least 351 W.
SurgeStarting watts are not published, so the surge check uses the 351 W running figure.
Average draw351 W: the running watts count for every hour it is on, as if the motor never paused.
A typical day351 W × 12 h = 4,212 Wh a day.
8 hours of running351 W × 8 h = 2,808 Wh usable, ÷ 0.85 = 3,304 Wh of rated capacity.
24 hours of running351 W × 24 h = 8,424 Wh usable, ÷ 0.85 = 9,911 Wh of rated capacity.
On the EcoFlow DELTA Pro Ultra X12,288 Wh × 0.85 = 10,445 Wh usable, ÷ 351 W = 29.8 h.

What moves the number

The figure is the rated draw of certified 35 pint models, a narrow 342 W to 358 W. The humidistat switches the compressor off when the room is dry enough, so real use depends on the room; the 12 hours a day here is our planning default. Older uncertified units draw more.

Questions

How many watts does a dehumidifier (35 pint) use?

About 351 W while running, from 342 W to 358 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 dehumidifier (35 pint)?

Yes. 50 of the 54 power stations in the Enough Watts data set can power it on its own. It takes at least 351 W of continuous output.

How long will a power station run a dehumidifier (35 pint)?

It depends on the battery. At 85% efficiency the smallest station that powers it, the EcoFlow RIVER 3 Plus (286 Wh), gives about 42 min. The largest, the EcoFlow DELTA Pro Ultra X (12,288 Wh), gives about 29.8 h.

Does a dehumidifier (35 pint) 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 351 W running figure, so leave headroom above that on your station.
