How many watts does a circular saw use — and what can run it?

A 15 A 7-1/4 in circular saw (DEWALT DWE575): 1,800 W running, about 3,600 W to start. Which power stations and generators can run it on a job site.

The representative saw is the DEWALT DWE575, a 7-1/4 in corded circular saw with a 15 A motor, as DEWALT lists it. The site turns that into 1,800 W (15 A × 120 V). DEWALT publishes no starting figure, so the 3,600 W is the top of the 2,400–3,600 W range for a 7-1/4 in circular saw on the Champion generator wattage chart. The same chart gives 1,200–1,800 W running, so 1,800 W is the heavy end.

What changes the draw

The 15 A is the motor's rating. Spinning freely between cuts it draws less; ripping thick or wet lumber, or using a dull blade, pushes it toward the rating. A saw runs in short bursts, so the page assumes half an hour of cutting a day, 900 Wh.

Why the starting draw matters

Every pull of the trigger starts the motor from rest, and the start draws far more than the running figure for a moment. On a battery station that start decides the fit more often than the running figure: several 2,000 W-class stations have peaks below 3,600 W and fail. With other tools or lights connected, their running watts are added on top (how loads are added).

Reading the tables

Runtime is for the saw cutting continuously at 1,800 W — a long cut that never ends. Example: the EcoFlow DELTA 3 record has no maker factor, so the default 0.85 applies: 1,024 Wh × 0.85 ÷ 1,800 W = 0.5 hours of motor-on time.

Power stations that can run it

Pass = continuous output ≥ 1800 W and peak output ≥ 3600 W. Runtime = capacity × maker's factor ÷ 1800 W, nothing else plugged in. Method.

Frequently asked questions

How many watts does a circular saw use?
The DEWALT DWE575 has a 15 A motor, per DEWALT's product page; 15 A × 120 V is 1,800 W. For the start, this page uses 3,600 W, the top of the 2,400–3,600 W range for a 7-1/4 in saw on the Champion chart.
Can a power station run a circular saw?
Only one rated 1,800 W continuous with a 3,600 W or higher peak. The EcoFlow DELTA 3 (1,800 W / 3,600 W) meets both exactly; the Anker SOLIX C1000 Gen 2 has 2,000 W continuous but a 3,000 W peak, and fails.
Can a Honda EU2200i run a circular saw?
Not by this page's figures. The Honda EU2200i is rated 1,800 W, enough to keep the saw running, but its 2,200 W max is below the 3,600 W starting figure. The Honda EU3200i (3,200 W max) also falls short.
