What size power station for an electric drill (corded)?
It needs a station with at least 600 W of continuous output and a surge rating of at least 1,200 W to start it. At the default 85% efficiency it takes about 706 Wh of rated capacity for its typical 1 h a day, and 5,647 Wh for 8 hours of running. 44 of the 54 power stations in the Enough Watts data set can power it. The smallest one that keeps it going for 8 hours of running is the EcoFlow DELTA Pro Ultra (6,144 Wh).

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

The math
Worked with the typical figure, as the calculator does it.
- Output600 W running, so the station's continuous output must be at least 600 W.
- Surge1,200 W to start, so its surge rating must be at least 1,200 W.
- Average draw600 W: the running watts count for every hour it is on, as if the motor never paused.
- A typical day600 W × 1 h = 600 Wh a day.
- Typical 1 h a day600 W × 1 h = 600 Wh usable, ÷ 0.85 = 706 Wh of rated capacity.
- 8 hours of running600 W × 8 h = 4,800 Wh usable, ÷ 0.85 = 5,647 Wh of rated capacity.
- On the EcoFlow DELTA Pro Ultra6,144 Wh × 0.85 = 5,222 Wh usable, ÷ 600 W = 8.7 h.
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 1/2 inch drill runs at 400 W to about 600 W; an 8 amp drill reaches 960 W at its nameplate, and hammer drills draw more. The start, about 1,200 W, matters more than the hours: drilling comes in short bursts.
