What size power station for a circular saw (7-1/4 inch, corded)?

It needs a station with at least 1,400 W of continuous output and a surge rating of at least 3,000 W to start it. At the default 85% efficiency it takes about 1,647 Wh of rated capacity for its typical 1 h a day, and 13,176 Wh for 8 hours of running. 38 of the 54 power stations in the Enough Watts data set can power it. None of them keeps it going for 8 hours of running.

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: 1,400 W
Running, low to high: 1,200 W to 1,800 W
Starting: 3,000 W2,400 W to 3,600 W, 2.1 times running
Typical use a day: 1 hhours the motor actually runs
Average draw while on: 1,400 W
Voltage: 120 V

Assumes the motor runs the whole time; real use is often less.

The math

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

Output1,400 W running, so the station's continuous output must be at least 1,400 W.
Surge3,000 W to start, so its surge rating must be at least 3,000 W.
Average draw1,400 W: the running watts count for every hour it is on, as if the motor never paused.
A typical day1,400 W × 1 h = 1,400 Wh a day.
Typical 1 h a day1,400 W × 1 h = 1,400 Wh usable, ÷ 0.85 = 1,647 Wh of rated capacity.
8 hours of running1,400 W × 8 h = 11,200 Wh usable, ÷ 0.85 = 13,176 Wh of rated capacity.
On the BLUETTI Elite 100 V21,024 Wh × 0.85 = 870 Wh usable, ÷ 1,400 W = 37 min.

What moves the number

Blade load moves the draw: dense stock and a dull blade push a 15 amp saw toward 1,800 W. Each start asks for about 3,000 W, 2.1 times the typical running figure, and that start is what rules out small stations.

Cuts come in bursts, so the battery lasts longer than the full hour of running counted here.

Questions

How many watts does a circular saw (7-1/4 inch, corded) use?

About 1,400 W while running, from 1,200 W to 1,800 W across the models in our sources. It needs about 3,000 W for a moment at start. 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 circular saw (7-1/4 inch, corded)?

Yes. 38 of the 54 power stations in the Enough Watts data set can power it on its own. It takes at least 1,400 W of continuous output and a surge rating of 3,000 W.

How long will a power station run a circular saw (7-1/4 inch, corded)?

It depends on the battery. At 85% efficiency the smallest station that powers it, the BLUETTI Elite 100 V2 (1,024 Wh), gives about 37 min. The largest, the EcoFlow DELTA Pro Ultra X (12,288 Wh), gives about 7.5 h.

Why does a circular saw (7-1/4 inch, corded) need a high surge rating?

Its motor draws about 3,000 W for a moment at start, 2.1 times its 1,400 W running figure. A station whose surge rating is below that cannot start it, even when the continuous output is enough. 38 of the 54 stations pass that check.
