What size power station for an RV fresh water pump?

It needs a station with at least 90 W of continuous output (starting watts not published, so the check uses running watts). At the default 85% efficiency it takes about 53 Wh of rated capacity for its typical 30 min a day, and 106 Wh for 1 hour of use. 54 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 Elite 10 Mini (128 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: 90 W
Running, low to high: 60 W to 120 W
Starting: Not publishedmotors often need 2 to 3 times their running watts to start
Typical use a day: 30 minhours the motor actually runs
Average draw while on: 90 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.

Output90 W running, so the station's continuous output must be at least 90 W.
SurgeStarting watts are not published, so the surge check uses the 90 W running figure.
Average draw90 W: the running watts count for every hour it is on, as if the motor never paused.
A typical day90 W × 30 min = 45 Wh a day.
Typical 30 min a day90 W × 30 min = 45 Wh usable, ÷ 0.85 = 53 Wh of rated capacity.
1 hour of use90 W × 1 h = 90 Wh usable, ÷ 0.85 = 106 Wh of rated capacity.
On the BLUETTI Elite 10 Mini128 Wh × 0.85 = 109 Wh usable, ÷ 90 W = 1.2 h of use.

What moves the number

An RV water pump runs only while someone has a tap open, so its energy is small. Its 12 V rating sets the most it draws: 60 W for a small pump to 120 W for a high flow one. Wired to 12 V, as it is in a camper, it skips the inverter.

Questions

How many watts does an RV fresh water pump use?

About 90 W while running, from 60 W to 120 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 an RV fresh water pump?

Yes. All 54 power stations in the Enough Watts data set can power it on its own. It takes at least 90 W of continuous output.

How long will a power station run an RV fresh water pump?

It depends on the battery. At 85% efficiency the smallest station that powers it, the BLUETTI Elite 10 Mini (128 Wh), gives about 1.2 h of use. The largest, the EcoFlow DELTA Pro Ultra X (12,288 Wh), gives about 4.8 days of use.

Does an RV fresh water pump 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 90 W running figure, so leave headroom above that on your station.
