Ooni Volt 2 power consumption is rated at 1600 W on every regional rating plate in Ooni’s manual. The US and Canada model runs on 120 V, while the UK, EU, Australia and New Zealand models run on 220 to 240 V. Both use 50 to 60 Hz.
The rating is a ceiling, not a fixed cost per pizza. Standby uses only 0.7 W, and the oven’s timers and cool-down rules decide how long it stays on.
This summary follows Ooni’s published manual. For circuit, outlet or wiring questions, follow the manual and a licensed electrician.
Ooni Volt 2 power consumption by region
Ooni Volt 2 power consumption is rated at 1600 W on every regional plate, which is the most it draws while heating. The supply voltage changes by region, but the wattage does not.
| Rating plate | Supply | Frequency | Rated power |
|---|---|---|---|
| US and Canada | 120 V | 50 to 60 Hz | 1600 W |
| UK, EU, Australia and New Zealand | 220 to 240 V | 50 to 60 Hz | 1600 W |
The figures come from the rating plates printed in the Ooni Volt 2 manual. The manual does not publish an average draw for a full cook, so treat 1600 W as the planning ceiling. To find your model’s plate, check the label on the oven itself; the US and Canada plate lists SKUs UU-P35A00 and UU-P35B00.
What the rating means for amps and extension cords
At 1600 W, the Volt 2 draws about 13.3 amps on a 120 V supply and about 6.7 to 7.3 amps on 220 to 240 V. These amp figures are our own calculation using current equals power divided by voltage, not numbers printed by Ooni. Ooni Volt 2 power consumption on a 220 to 240 V supply therefore draws fewer amps than on 120 V.
The manual does not state a required circuit size or breaker rating. Check the circuit label, and ask a licensed electrician if you are unsure the outlet can carry the load.
If you must use an extension cord, the manual sets three conditions:
- The cord’s marked electrical rating must be at least as high as the oven’s rating.
- The cord must be arranged so it does not hang over the counter or table edge.
- The cord must be a grounding-type 3-wire cord.
Standby power and automatic shut-off
In standby, Ooni Volt 2 power consumption falls to 0.7 W, and its display shows dashes instead of a temperature.
If the oven is cold, standby starts 5 seconds after you press the standby button. If it is hot, the oven cools for 30 minutes before it enters standby, and the manual says to wait that long before you switch off the power switch or unplug it.
The oven also enters standby on its own after 2 hours with no interaction or active timer in cooking modes, or after 14 hours in dough proofing mode. The power switch at the back turns the oven off, but the manual says to let it cool in standby for 30 minutes first. At 0.7 W, a full 24 hours in standby uses about 0.0168 kWh, which is our calculation. At the EIA’s 18.16 cents per kWh, a whole year of continuous standby would use about 6.1 kWh and cost roughly $1.11, so Ooni Volt 2 power consumption in standby costs very little.
How to estimate electricity cost per session
Ooni Volt 2 power consumption is measured in kilowatt-hours, and your bill charges for each one. Multiply the rated power by the hours the oven is on, then multiply by your rate per kilowatt-hour.
- Convert the rating to kilowatts: 1600 W divided by 1,000 is 1.6 kW.
- Multiply by the hours on: 1.6 kW for half an hour is 0.8 kWh.
- Multiply by your rate from your own electricity bill.
To price Ooni Volt 2 power consumption with a real rate, EIA’s Electric Power Monthly (Table 5.6.A, released October 23, 2026) lists the U.S. average residential price at 18.16 cents per kWh for August 2026, up from 17.57 cents in August 2025. At 18.16 cents, that half hour at full rating costs about 14.5 cents. State and utility rates differ, so replace the national average with the rate on your own bill.
Using the same rate, Ooni Volt 2 power consumption at full rating works out as follows for common session lengths. These are our own calculations, and they assume the oven draws 1600 W the entire time, which overstates real use once the oven reaches temperature.
- 30 minutes: 0.8 kWh, about 14.5 cents.
- 1 hour: 1.6 kWh, about 29 cents.
- 2 hours: 3.2 kWh, about 58 cents.
Ooni Volt 2 power consumption in preheat is not separately listed, and the heating indicator pulses while the oven preheats and stays steady once it reaches the target temperature, according to the manual. Preheat time is therefore part of your session, and the manual does not time it. For the Neapolitan preset, the manual sets 810 °F / 430 °C with a 1:30 cook timer, and Boost gives a Neapolitan-style pizza in 90 seconds.

Electrical safety rules from the manual
For Ooni Volt 2 power consumption at 1600 W, the manual requires a properly grounded outlet, and the plug goes into the oven before the wall outlet.
- Use only properly grounded or earthed outlets.
- Attach the plug to the oven first, then plug the cord into the wall. To disconnect, turn any control to off, then remove the plug.
- Use the oven indoors only. Do not use it outdoors, and keep 10 cm (4 in) of space on each side and 15 cm (6 in) above.
- Do not immerse the oven, cord or plug in water or any other liquid.
- Do not operate it with a damaged cord or plug.
- Unplug the oven and let it cool completely before cleaning or moving it. See how to clean an Ooni pizza oven for care steps.
The manual also warns not to cook meat or fatty foods above 480 °F / 250 °C, because grease can ignite at high temperatures.
What the manual does not publish
The manual gives Ooni Volt 2 power consumption as a rated wattage and a standby draw, but it does not give an average power figure per pizza or per hour of cooking. It also gives no energy figure for each preset.
If you need an exact number for your own kitchen, a plug-in energy meter will read the Ooni Volt 2 power consumption from your outlet, which is the only way to learn the average draw once the oven is up to temperature. Until then, the formula above gives a worst-case estimate, because it assumes the full rating for the whole session. For the oven’s size and clearances, see the Ooni Volt 2 dimensions, and for a comparison, the Ooni Volt 12 power consumption page.
Frequently Asked Questions
How many watts does the Ooni Volt 2 use?
Ooni Volt 2 power consumption is rated at 1600 W on every regional rating plate in Ooni’s manual. That is the maximum it draws while heating, and standby uses only 0.7 W.
Does the Volt 2 use 120 V or 240 V?
It depends on the model you bought. The US and Canada plate says 120 V, and the UK, EU, Australia and New Zealand plates say 220 to 240 V. Check the plate on your own oven before you plug it in.
How much power does the Volt 2 use on standby?
The manual lists 0.7 W in standby, and the display shows dashes. The oven enters standby on its own after 2 hours with no interaction or active timer in cooking modes.
Can I use an extension cord with the Volt 2?
The manual allows an extension cord only if its marked rating is at least as high as the oven’s rating and it is a grounding-type 3-wire cord. It should not hang over the counter edge.
Can the Volt 2 run outdoors?
No. The manual says not to use the oven outdoors, and it is designed for indoor use only.
How do I estimate the cost of one cooking session?
Ooni Volt 2 power consumption cost is estimated by multiplying the 1.6 kW rating by the hours the oven is on, then by your electricity rate per kilowatt-hour. The result is a worst-case estimate, because the rating is a maximum.
Before you plug in, confirm the outlet matches the plate on your own oven, because Ooni Volt 2 power consumption figures pair with 120 V or 220 to 240 V supplies by region. Use 1600 W as your planning ceiling and the manual’s safety rules as the hard limit.
