Ender 3 power consumption: watts, kWh and cost

An original Ender 3 uses about 125 W while printing PLA, or 0.125 kWh an hour, which costs 2.2 cents at the US average price of $0.179 per kWh. Later models measure lower: about 110 W for the V2 and 80 W for the S1. The rated maximum is 270 W on the original and 350 W on the V2 and every model since.

How much power does an Ender 3 use?

An original Ender 3 averages about 125 W while printing PLA at 200 °C with a 60 °C bed, and peaks near 277 W while heating up. Published measurements put the Ender 3 V2 at 110 W and the Ender 3 S1 at about 80 W. An hour of printing uses 0.08 to 0.125 kWh.

Model	Rated power	Power supply	Heated bed (24 V, 235 × 235 mm)	Measured average, PLA
Ender 3	270 W	24 V, 270 W	220 W	125 W
Ender 3 V2	350 W	24 V Mean Well	220 W	110 W
Ender 3 S1	350 W	24 V Creality CMS-350-24	270 W	about 80 W
Ender 3 V3 SE	350 W	not named	270 W	not published
Ender 3 V3 KE	350 W	not named	270 W	not published

Each measured figure comes from one tester’s plug-in meter, not from Creality. 3DSolved logged the original Ender 3 with an electricity usage monitor. Furkan Ermanas Yabancı measured a V2 with a smart socket at a 200 °C nozzle, a 60 °C bed and 25 °C room temperature. 3DPrintBeginner read the S1’s draw from a Blitzwolf smart socket.

Your own room temperature, bed setting and print will move the average.

What is the Ender 3 wattage?

The rated wattage is 270 W for the original Ender 3 and 350 W for the V2, S1, V3 SE and V3 KE. That rating is the most the supply can deliver, not what the meter bills. Real peaks sit below it: 277 W on the original Ender 3 and about 290 W on the S1, both while the bed and hotend heat together.

At 120 V, 270 W is 2.25 A and 350 W is 2.9 A.

A print longer than 3 hours is a continuous load under the National Electrical Code (NEC), so it may use only 80 percent of the breaker: 12 A on a 15 A circuit. One 350 W Ender 3 uses 24 percent of that. Four of them reach 11.7 A, right at the limit. The circuit capacity calculator adds up everything else on the same breaker.

Idle draw is small. 3DPrintBeginner measured the S1 at about 8 W switched on and idle.

How much power does the Ender 3 heated bed use?

The original Ender 3 and the V2 use a 220 W, 24 V bed. The S1, V3 SE and V3 KE use a 270 W, 24 V bed. Both are 235 × 235 mm. The bed is 77 to 81 percent of each printer’s rated power, which is why it sets both the peak and the bill.

Once at temperature the bed cycles on and off. 3DSolved measured the original Ender 3’s bed at 80 W on average at 60 °C and up to 260 W while heating. That is 64 percent of the printer’s 125 W average. The hotend averaged about 30 W, and the motors and board took the remaining 15 W.

Heat-up takes minutes, not hours:

• Ender 3: the bed reaches 110 °C in about 5 minutes, according to Creality.
• Ender 3 S1: 60 °C in 2 minutes 5 seconds and 100 °C in 6 minutes 15 seconds, as 3DPrintBeginner timed it.

Five minutes at the 277 W peak uses 0.023 kWh, under half a cent. Because the bed takes most of the steady draw, its temperature setting is the biggest lever on the bill. To size a replacement supply for a bigger bed, use the power supply calculator.

How much does it cost to run an Ender 3?

Multiply the average watts by the hours and divide by 1,000 for kWh, then multiply by your price per kWh:

kWh  = average watts × hours ÷ 1000
cost = kWh × price per kWh

4-hour PLA print, original Ender 3: 125 W × 4 h ÷ 1000 = 0.50 kWh  →  0.50 × $0.179 = $0.090

Model	Average	kWh per hour	Cost per hour	4-hour PLA print
Ender 3	125 W	0.125	$0.022	0.50 kWh, $0.090
Ender 3 V2	110 W	0.110	$0.020	0.44 kWh, $0.079
Ender 3 S1	80 W	0.080	$0.014	0.32 kWh, $0.057
Any 350 W model at full rating	350 W	0.350	$0.063	1.40 kWh, $0.25

A 4-hour PLA print costs 6 to 9 cents. The last row is a ceiling no Ender 3 reaches over a whole print. The price is the U.S. Energy Information Administration’s residential average for the 12 months ending June 2026. The electricity cost calculator reruns this with the rate on your own bill or a smart plug reading.

How much power does the Ender 3 V3 SE use?

Creality rates the Ender 3 V3 SE at 350 W on 100 to 120 V or 200 to 240 V AC, with a 270 W, 24 V bed. No measured average has been published for it, or for the V3 KE. The S1 has the same 350 W rating and the same 270 W bed, and it measured about 80 W on PLA. Plan on 80 to 125 W, or 1.4 to 2.2 cents an hour, until a smart plug gives you your own figure.
