Ooni Volt 12 first look: what an indoor electric pizza oven can and cannot do

Ooni's first indoor electric pizza oven reaches 850°F and fits a 12-inch pie. Here is what reviewers report it does well, where it falls short, and what to check now that the Volt 2 exists.

What the Volt 12 is, and where it stands now

The Ooni Volt 12 is a countertop electric pizza oven. It was the brand's first oven designed for use indoors, and it can also be used outdoors. Engadget reviewed it in April 2023 and gave the launch price as $999. Engadget and Bob Vila both list its power draw as 1,600 watts. It heats a 13-inch square stone that holds one 12-inch pizza at a time.

Ooni says the oven reaches its 850°F (450°C) maximum in about 20 minutes. The dial in Ooni's Essentials Guide starts at 250°F (150°C). That top temperature is why reviewers compare the Volt 12 with Ooni's outdoor gas and wood ovens rather than with toaster ovens. Gear Patrol said it cooks at temperatures “nearly as high as outdoor pizza ovens.” Engadget found its pizza matched Ooni's outdoor models across several crust styles.

Timing matters if you are reading about it now. In September 2025, Ooni announced the Volt 2 as the Volt 12's successor. It went on sale on October 1, 2025, at $699 on Ooni.com. The electric-oven menu on that announcement page lists only the Volt 2. A Volt 12 you find today is probably leftover stock, a marketplace listing or a used unit. So the real question is not whether it is good, but whether it is good at the price you are offered.

Who it makes sense for

Reviewers make the strongest case for people who make pizza often and want very high heat all year without running a gas or wood oven outside. Bob Vila's reviewer rated it 5/5 and called it worth the money for serious home pizza makers. The same review also called it one of the pricier electric pizza ovens. Engadget's verdict was that the choice depends on where you will cook most often, inside or out.

The Volt 12 is rated for both indoor and outdoor use, and Bob Vila describes it as a year-round oven. That suits someone who wants one oven for the kitchen in winter and the patio in summer. Ooni's guide does say to store it indoors in a dry place. It is a weaker fit for small kitchens, for people who make pizza a few times a year, and for anyone who wants a general-purpose countertop oven. Bob Vila's reviewer did cook steak and roasted vegetables in it, but its size and controls are built around pizza.

The features that matter

Gear Patrol and Engadget describe three dials on the Volt 12: time, temperature and balance. The balance dial splits heat between the top and bottom heating elements. That control is what lets one oven cook both a fast Neapolitan pizza and a slower New York-style pie. Gear Patrol notes that you can only adjust balance once the oven reaches the set temperature, and suggests turning it fully toward the top for Neapolitan.

Cooking times vary by style. Ooni claims about 90 seconds per pizza, and Bob Vila's reviewer reported crisp, blistered pizzas in under two minutes. Gear Patrol says Ooni's app suggests about five minutes at 650°F for New York style. Engadget found that it needed less turning than open-flame ovens.

Boost: Ooni says it recharges the stone faster between bakes. Engadget measured recovery at about 45 seconds.
Timer: Gear Patrol says it moves in 30-second steps and does not switch the oven off. Bob Vila says the chime can be muted.
Door and light: a front door holds heat in, and Engadget found the interior light made it easy to check on a pizza.
First use: Bob Vila and Engadget both say Ooni recommends running it at 850°F for 20 minutes before the first bake.

What it cannot do, or does poorly

Size is the first limit. It cooks one 12-inch pizza at a time. Gear Patrol measured it at about two feet deep, 21 inches wide and 11 inches tall, and its reviewer had a large kitchen bar to put it on. Bob Vila lists the weight as 39.2 pounds and recommends two people for unboxing. That review also warns that if counter space is tight, you may not want to leave it out.

Smoke is the second limit. Gear Patrol called the oven “a bit of a smoke machine.” A clean oven produced little smoke, but fallen toppings and sticky dough left residue that smoked heavily on later bakes. The reviewer said better kitchen ventilation would reduce the problem.

Cleaning is the third. Gear Patrol reports that the stone should not be washed or wetted. Ooni's method is to brush off debris and flip the stone so the rest burns away. Ooni also advises against cleaning the interior because of the electronics. Bob Vila adds that the glass door and exterior should only be wiped once fully cool.

Heat and handling also take care. Bob Vila says the door gets very hot and is easy to bump while turning or removing a pizza. Engadget says to wait at least an hour before covering or storing the oven. Ooni's guide says not to put plastic, rubber or silicone items inside, and to remove flammable items from the area around it. Expect a learning curve: Bob Vila's reviewer burned the edges of the first couple of pizzas and suggests beginners avoid the highest setting.

Volt 12 or Volt 2?

The Volt 2 changes the comparison. Ooni says its frame is 30% smaller than the Volt 12's. Engadget, reviewing it in November 2025, found it only slightly smaller and still heavy at nearly 39 pounds. On the Volt 2, buttons and a single larger knob replace the Volt 12's three dials. Engadget called the new display a large improvement, because the Volt 12's dials could not be read from a distance. The Volt 2 also adds sensor-based heat control, which Ooni calls Pizza Intelligence, plus pizza presets and dough-proofing, oven and broil modes.

There is one trade-off. Engadget lists the Volt 2 as indoor use only. It also found that, despite its steam and smoke filter, the oven still vents steam out of the back. If outdoor use matters to you, the Volt 12 still has a reason to exist. If it does not, the Volt 12 needs to cost clearly less than the Volt 2 to make sense.

Open questions to check before buying

Most risks with a Volt 12 today come from the listing, not the oven. Check these points first.

Condition and warranty: is it new, refurbished or used? Bob Vila (August 2024) listed a one-year warranty and said Ooni's extended warranty did not cover the Volt. Confirm current terms with Ooni.
Space: plan for a footprint of roughly 24 by 21 inches, plus the clear space and airflow Ooni's guide asks for.
Ventilation: check whether a hood or exhaust fan reaches the spot where the oven would sit.
Power: check that the outlet and circuit can handle a 1,600-watt appliance alongside whatever else runs on it. For imported units, confirm it is built for your country's mains voltage.
Accessories: Bob Vila says none are included and calls a 12-inch peel essential.
Price: compare the offer against the Volt 2's $699 US launch price.

Weight	39.2 lb (Bob Vila)	Nearly 39 lb (Engadget)
Controls	Three dials: time, temperature, balance	Buttons, one knob and a display
Cooking modes	Manual heat balance plus Boost	Pizza presets, dough proofing, oven and broil modes
Where it can be used	Indoors and outdoors	Indoors only (per Engadget)

Reviewers agree the Volt 12 makes pizza close to what Ooni's outdoor ovens produce, on a kitchen counter. Its drawbacks are size, smoke when residue builds up, and limited cleaning options. Now that the cheaper Volt 2 exists, it makes most sense at a clear discount, or for buyers who also want to use it outdoors.

What works

Common questions

Can the Ooni Volt 12 really be used indoors?

Yes. Ooni designed it for indoor and outdoor use. Its guide asks for a level, stable surface with plenty of room for airflow, and for flammable items to be cleared away. Gear Patrol reports that smoke becomes a problem once food residue builds up, so good kitchen ventilation helps.

How hot does it get and how long does a pizza take?

Ooni lists a maximum of 850°F (450°C), reached in about 20 minutes. Ooni claims about 90 seconds per pizza. Bob Vila's reviewer reported under two minutes, and New York style takes longer at lower heat.

Can it cook anything besides pizza?

Bob Vila's reviewer cooked steak and roasted vegetables in it, and Engadget noted room for pan pizza and other baking. The cooking space is still sized around a single 12-inch pizza.

How do you clean it?

Gear Patrol reports that the stone should not be wetted. Ooni's approach is to brush off debris and flip the stone so leftover residue burns off. Ooni also advises against cleaning the interior because of the electronics. Bob Vila says to wipe the glass and exterior only once the oven is fully cool.

Should I buy a Volt 12 or the Volt 2?

The Volt 2 launched at $699, with easier-to-read controls, presets and a smaller frame. Engadget lists it as indoor use only. The Volt 12 makes sense if you want outdoor use too, or if it is offered well below the Volt 2's price.
