Summary
A 12-quart countertop air fryer oven with six cooking functions, 12 presets and a rotisserie, aimed at households that want oven-style cooking without heating a full-size oven. The one thing to check before buying: no independent test has been published for this exact model, and Chefman’s other air fryers have measured poorly on temperature accuracy, so treat the capacity and cooking claims as unconfirmed.
Strengths
- Six functions cover air frying, baking, roasting, rotisserie, dehydrating and reheating.
- Twelve presets and a capacitive touch screen simplify setup.
- The 12-quart cavity and three included racks let you cook in batches.
- The rotisserie spit, forks and retrieval tool are included, not sold as extras.
- Dishwasher-safe parts and a removable drip tray make cleanup easier.
- cETL approved with a one-year warranty.
Weaknesses
- No independent test of the exact 12-quart model exists, so cooking performance is unverified.
- Consumer Reports measured the 6.3-quart sibling at 2.7 quarts against a 6.3-quart claim, a large gap.
- TechGearLab’s tests of two other Chefman air fryers scored temperature accuracy at 3.5/10 and 5.3/10.
- Wirecutter’s rotisserie testing on a competing oven produced a pale, unevenly roasted chicken.
- Chefman does not publish the rotisserie’s maximum load or name the 12 presets.
- The one-year warranty is shorter than Breville’s two years and Cuisinart’s three.

Full research notes and sources
Cooking capacity and what’s included
The RJ38-RDO-V12 is a 12-quart (11.35 L) countertop oven that covers air fry, bake, roast, rotisserie, dehydrate and reheat. The box includes three cooking racks, a stainless-steel rotisserie spit with forks, a retrieval tool and a drip tray, so the rotisserie hardware is not an extra purchase. Chefman does not state how much weight the spit can turn, and the 12 presets are not named on the product page — check the manual for what each one cooks.
What the independent tests show
No lab has published instrumented results for the exact RJ38-RDO-V12. The closest data is Consumer Reports’ test of the smaller 6.3-quart sibling, the RJ38-6-RDO, which scored 78/100. CR measured that unit’s usable capacity at 2.7 quarts against a 6.3-quart claim, a gap worth remembering when you read “12 quart” here. TechGearLab tested two other Chefman air fryers and recorded temperature accuracy of 5.3/10 on the 2-quart Compact and 3.5/10 on the 8-quart TurboFry Touch, which measured about 17°F below its set temperature. Wirecutter’s rotisserie testing on a competing oven produced a pale, unevenly roasted chicken, and it warns that spit attachments in this category are often hard to assemble. None of this is confirmed for the V12, but it is the pattern around it.
Running costs and cleaning
Consumer Reports puts the sibling’s electricity cost at about $6.27 for one hour a week for 52 weeks at 350°F. That figure is for the 6.3-quart model, but the 12-quart V12 draws the same 1700W, so treat it as a rough guide. The food-contact parts are dishwasher-safe and the drip tray lifts out, which matters on an oven with three racks and a rotisserie to clean.
Prices and other options
Chefman lists the RJ38-RDO-V12 at $129.99, down from $149.99 regular, on its own site (captured July 2025). The sibling RJ38-RDO-PV12, which adds an integrated smart thermometer, is $99.47, down from $129.99. Consumer Reports lists the 6.3-quart sibling at $150.00. In Wirecutter’s air fryer toaster oven guide, the recommended models are the Cosori CO130-AO at $169, the Breville Smart Oven Air Fryer Pro at $320 and the Cuisinart TOB-260N1NAS at $300. If the thermometer matters more than the 12-quart size, the cheaper sibling is the better value; otherwise, these are the tested reference points in the same price band.
Which model this is
This page covers the RJ38-RDO-V12, the 12-quart model with a capacitive touch screen and a matte-black finish. Do not confuse it with the RJ38-RDO-PV12, which shares the 12-quart, 1700W, 95–450°F platform but adds a smart thermometer, or with the smaller 6.3-quart RJ38-6-RDO. The V12 and PV12 pages disagree on which measurement is width and which is depth, so measure your counter before ordering.
