The deciding specification is the electrical draw each maker publishes, and only one of these four electric ovens publishes volts, amps and watts together.
By the Lush Editorial Team·Researched & Compared
I compared the wattage, voltage and amperage each listing publishes against its top temperature, its control range, bake and preheat times, weights and stated sizes, and set the four electric ovens beside one propane oven that publishes its output in BTU, using only each maker's own text.
A countertop oven publishing 120 volts, 12.5 amps and 1500 watts together, with an adjustable thermostat from 150 to 500 degrees F in 25 degree increments, a one touch 450 degrees F setting for 10 minutes, calrod elements and a removable clean out tray.
An indoor countertop oven publishing 1200 watts on a standard 120 volt outlet through a three prong cord, heating to 800 degrees F with separate upper and lower knobs, baking a 12 inch pizza in four to six minutes on a ceramic stone that lifts out.
A touchscreen countertop oven publishing 1700 watts at 120 volts with both elements adjustable from 300 to 800 degrees F, five presets for Neapolitan, New York, thin crust, pan and frozen, a double paned window and a stone and peel included.
A countertop oven reaching 750 degrees with an element system that adjusts itself, five style presets and a manual mode that selects which elements run, a cordierite stone and a double pane window, published at 32.3 lb and no electrical figure anywhere.
A propane oven publishing a steady 13,000 BTU adjustable by knob, with automatic ignition, a 13 inch stone that rotates through 360 degrees by a side knob, folding legs for storage, stated ready in about 15 minutes and a bake in two.

Wisco publishes 120 volts, 12.5 amps and 1500 watts, which no other listing here matches. Chefman publishes 1700 watts at 120 volts and Piezano 1200 watts at 120 volts. Breville publishes no electrical figure at all, only a ceiling of 750 degrees. Grills House needs no socket and publishes 13,000 BTU instead.

Wisco, because it is the only one that publishes the figure a circuit is rated in. Its specification line reads volts 120, amps 12.5, watts 1500. Chefman publishes 1700 watts at 120 volts and Piezano 1200 watts at 120 volts, both of which can be converted to amps by arithmetic. Breville publishes no electrical figure at all, so there is nothing to convert.
Not on this page. Piezano publishes 1200 watts and a ceiling of 800 degrees F. Chefman publishes 1700 watts and the same 800 degrees F. Wisco publishes 1500 watts and a thermostat that stops at 500 degrees F. The oven with the most electrical detail is the coolest of the four, and the one with no electrical detail states 750 degrees.
The listing does not say. Its ten bullets describe an element system that adjusts itself, five style presets, a manual mode that chooses which elements run, conductive, radiant and convective heat, a double pane window and insulation, and a temperature of 750 degrees with no unit attached. Nowhere in that is a watt, a volt or an amp, on the heaviest oven here at 32.3 lb.
It is the same idea in another unit and it comes with no socket attached. Grills House publishes a steady 13,000 BTU output adjustable by a knob, with automatic ignition, a 13 inch stone that rotates through 360 degrees, folding legs, a 15 minute preheat and a two minute bake. What it does not publish is a temperature, so the heat is described by input rather than by result.
Piezano on its dimension field, at 8.3 lb, and the listing then disagrees with itself: one bullet describes the oven as about 6 lbs with a roughly 14 inch counter footprint. This page reports both figures and ranks on neither, and notes that either way it is far below the 19.0 lb, 23.32 lb, 28.7 lb and 32.3 lb published for the rest.
It is the lowest ceiling here by 250 degrees, and it is also the only one with a stated thermostat rather than presets: 150 to 500 degrees F adjustable in 25 degree increments, plus a one touch setting of 450 degrees F for 10 minutes. Two of these ovens reach 800 degrees F. What Wisco offers instead is a temperature you set to a number and a draw you can look up.

Four of these five ovens plug in and one does not. For a kitchen with a single free socket the specification is therefore electrical before it is culinary, and on that question the pool answers unevenly. Three publish a wattage, three publish a voltage, and exactly one publishes an amperage.
Those draws read 1200, 1500 and 1700 watts, all on a 120 volt supply. The fourth electric oven publishes no electrical figure of any kind. The fifth runs on propane and publishes 13,000 BTU instead, which is the same quantity in a unit no household breaker is labeled in.

What the table cannot settle is whether any of these will run beside a kettle. That needs an amperage and a circuit rating, and one listing in five supplies the first half. Watts divided by volts gives amps for the other two, but a buyer should not have to do a maker’s arithmetic to know whether a breaker will hold.
Wisco’s specification list is five bullets long and one of them reads volts 120, amps 12.5, watts 1500. That single line does more for a kitchen short of sockets than any other sentence in this pool, because a household circuit is rated in amps and 12.5 is most of a 15 amp circuit on its own.
The rest of the listing is equally plain. An adjustable thermostat from 150 to 500 degrees F in 25 degree increments, a quick one touch setting of 450 degrees F for 10 minutes, long life calrod elements and a removable clean out tray. No stone, no presets, no window, and no marketing. It is the only pick here that lets you set a number rather than a style.
At 500 degrees F it is the coolest oven on this page by 250 degrees. Two of the four electric picks reach 800 degrees F, which is the range a Neapolitan crust is usually associated with, and Wisco does not claim to get there. What it claims is a thermostat you can trust to a 25 degree step.
It is also the only electric pick here that states its own size rather than leaving it to a field: 18 inches wide, 15 inches deep and 7.75 inches high, at 19.0 lb. For an oven whose whole argument is that you can predict its behavior, publishing the size in words fits the pattern.
Piezano publishes 1200 watts and tells you where to put it: a three prong cord into any standard 120 volt outlet, with no propane tank and no assembly. It heats to 800 degrees F, bakes a 12 inch pizza in four to six minutes, and has separate knobs for the upper and lower elements so the base and the cheese are managed independently.
Chefman publishes 1700 watts at 120 volts, the highest draw here, with both elements adjustable across a stated 300 to 800 degrees F and five touchscreen presets for Neapolitan, New York, thin crust, pan and frozen. Neither publishes an amperage. At 1700 watts on 120 volts the arithmetic matters, and the listing leaves it to the reader.
Breville’s listing is the longest here and the least useful for this question. Ten bullets describe an element system that adjusts itself, preset functions for five styles, a manual mode that selects which elements run, conductive heat for a charred base, radiant heat for a spotted crust, convective heat for toppings, a double pane window and insulation that keeps the outside cool.
Not one of them mentions a watt, a volt or an amp. Its temperature is given as up to 750 degrees, twice, without a unit. At 32.3 lb it is the heaviest oven on this page and the only one whose electrical demand is entirely unstated, which on a kitchen with one free socket makes it the hardest of the five to plan for.
Grills House answers the question by sidestepping it. It publishes a steady 13,000 BTU output adjustable through a knob, with automatic ignition, so the socket stays free for the kettle. Its 13 inch stone rotates through 360 degrees from a knob on the side, it preheats in about 15 minutes and bakes in two, and its legs fold for storage.
What it never publishes is a temperature. That is a curious omission on a gas oven, since every gas rival in this pool publishes one: 900 degrees F, 950 degrees F, 1110 degrees F. Grills House describes its heat entirely in terms of input, 13,000 BTU, and leaves the output to the stone and the two minute bake.
It is an outdoor oven, so it does not replace the electric picks so much as avoid them. At 28.7 lb plus a propane bottle it is heavier to move than every electric oven here but one, and the folding legs are what make that manageable. Its stated size, 16.36 by 26.86 by 10.02 inches, is published in its own words and matches its fields.
The trade is honest and it is the whole point of the page. If the socket cannot be spared, the oven goes on the patio and takes its fuel with it. If it can, the question becomes which of the four electric ovens tells you enough about its draw to be trusted on a shared circuit, and only one of them really does.
A circuit you are already worried about. Wisco, publishing 120 volts, 12.5 amps and 1500 watts, with a thermostat from 150 to 500 degrees F in 25 degree steps, a one touch 450 degrees F cycle, and a stated 18 by 15 by 7.75 inch body at 19.0 lb.
The lowest draw that still reaches 800. Piezano, publishing 1200 watts on a standard 120 volt outlet, 800 degrees F, separate upper and lower knobs, a 12 inch ceramic stone that lifts out and a four to six minute bake.
Presets instead of judgment. Chefman, publishing 1700 watts at 120 volts with both elements across 300 to 800 degrees F, five touchscreen presets, a double paned window, a stone and a peel, at 23.32 lb.
Controlling the elements yourself. Breville, stating 750 degrees and a two minute bake with five presets and a manual element mode, a cordierite stone and an insulated body, at 32.3 lb and with no electrical figure published.
Keeping the socket for something else. Grills House, a propane oven publishing 13,000 BTU with automatic ignition, a 13 inch rotating stone, folding legs, a 15 minute preheat and a two minute bake, at 28.7 lb and outdoors only.
Every figure above comes from the maker’s own listing text. These are the things we went looking for and could not source in any of them.
