Black+Decker Convection (CTO6335S) vs Cosori Air Fryer Toaster Oven Side-by-Side Comparison




Our Verdict
- Performance (50%)7.0/10
- Design (25%)6.6/10
- Usability (25%)6.1/10
- Performance (50%)8.0/10
- Design (25%)9.4/10
- Usability (25%)8.3/10
Between the Black+Decker Convection Toaster Oven (CTO6335S) and the Cosori Air Fryer Toaster Oven (CO130-AO), the latter—as our definitive best-to-buy pick wins by a landslide across all fronts. Nonetheless, the former still put up a good fight as our best budget pick.
Both are large digital toaster ovens with internal lighting and convection which usually cost more than their analog conventional counterparts. However, the Black+Decker is one of the cheapest units in the large category.
The Cosori is more expensive but it offers tremendous value in return. The Cosori has a more informative digital display, better responsive buttons, more toggle switches, an actually precise automatic preheat phase, and more accessories.
To top it all off, the Cosori has a higher power output to excel at all of our cooking tests, including toasting bread, baking pizza, roasting a whole chicken, and air-frying fries. Nonetheless, the Black+Decker delivered a solid performance, getting above average in all of the tests.

Toast




- Function: Toast
- Number Of Slices: 4
- Toast Level: 4/7
- Cooking Time: 5m 10s
- Second Batch: 3m
- Convection: No
With our Toast test, we were able to determine that level 4—5 minutes 10 seconds on the timer—was the best option scoring a 7/10. Levels 3 and 5 respectively had a lighter and darker than ideal, although even, surface color.
The toast level 4 of the Black+Decker scored a 7/10 for color. The four pieces had areas of different colors ranging from golden brown to just slightly golden. This was probably due to uneven heating of the elements and the convection fan not running.
Despite the color, the first batch was crispy on the outside and soft on the inside so we gave it a 7.5/10 for taste. Our head chef Tuyet Pham determined that it would go great with eggs benedict and omelet.
Even with the automatic toast time adjustment feature, the quality of the second batch was reduced in every aspect. The color was lighter and the texture was less crispy so we had to give it a 6/10 for consecutive usability. If you want the second batch to be the same as the first, lower the toast level by one.




- Function: Toast
- Number Of Slices: 4
- Toast Level: 2/7
- Cooking Time: 5m 49s
- Second Batch: 3m 50s
- Convection: No
We started our Toast test with four pieces of white bread. We ran the toast function at level 3. The results were good, but the color was a bit too brown to be ideal. After examining the outcome on level 2, it was clear that was the best option, earning a score of 7.6/10 in total. We also tried toasting at level 1, which resulted in lightly toasted bread, for reference.
At level 2, which automatically set the timer for 5 minutes 49 seconds, the four pieces of toast mostly had a beautiful golden brown color. However, the existence of lighter areas, especially on the bottom side, kept it from being perfect. We considered it worthy of an 8/10 for even surface color.
The taste deserved another 8/10 thanks to the toast’s crispy surface and soft, moist interior. Our head chef, Tuyet Pham, determined the toast would complement pretty much anything, including sandwiches, omelets, eggs benedict, and soup.
After the first batch of toast, we immediately placed the second batch in the oven. The toast level 2 program automatically reduced the time to 3 minutes 50 seconds to account for the last batch’s residual heat.
However, this seemed like too much of a reduction, since the toast came out mostly lacking in color. It wasn’t very crispy either, so we could only give the oven a 6.8/10 for consecutive usability.
Pizza




- Function: Bake
- Temperature: 450°F
- Cooking Time: 7m 30s
- Convection: Yes
The Black+Decker did an ok job of baking a 9-inch thick-crust meat pizza earning it a 6.8/10.
Compared to the recommended 10 minutes on the label, it took 7m 30s to bake the pizza, which was fairly solid. However, after comparing it to other toaster ovens in our Pizza test, we could only give it a 7.5/10.
The crust had a good golden brown color but was soft and a little dry — possibly due to the longer cooking time. Thus, it could only get a 7/10.
The toppings were mostly dry with an uneven coloring, plus the cheese wasn’t melty so it got a 6.5/10.
In the end, our chef gave the pizza a 6.5/10 for taste.




- Function: Bake
- Temperature: 450°F
- Cooking Time: 3m 30s
- Convection: Yes
The Cosori’s ability to maintain a high temperature really shined in our Pizza test, garnering a score of 7.6/10.
With a high power output and powerful convection system, it only took 3 minutes 30 seconds to bake a 9-inch thick-crust meat pizza placed on tray level 2. This was extremely fast and deserving of a 10/10, the same as the Cuisinart TOA-60 which has the current highest pizza score.
However, the short cooking time resulted in uneven heating in the pizza crust and toppings.
While the bottom right quarter of the crust was golden brown, the rest didn’t have much color. Only that well-cooked part was crispy while the rest was soft, so we gave the crust a 7/10.
The same happened to the toppings. The bottom right quarter had a lot of caramelization—to the point that the onions even charred—while the rest was only mildly caramelized. In addition, the cheese wasn’t very melty, so we gave the toppings a 7/10 as well.
Taste-wise, our chef said it would be better if it weren’t for the slight bitterness from the charred onions. She gave the pizza another 7/10.
Whole Roasted Chicken





- Function: Bake
- Temperature: 350°F
- Cooking Time: 1h
- Convection: Yes
Following our Whole Roasted Chicken test guidelines, we placed a 3 lb chicken on a broiling rack on a baking pan of the Black+Decker with plenty of space to spare. The abundance of space gave it some advantages over smaller units like the Breville BOV450XL despite a lower power output. Overall, the Black+Decker received a 7.7/10 for this test.
It took the oven 1 hour, the standard amount of time, to roast the chicken to a desirable color so we gave it an 8/10. The skin came out a light golden color but it was uneven despite being flipped after the first 40 minutes. In addition, it was soft, so it got a 6.5/10.
The chicken was thoroughly cooked but the internal temperature was a tad bit high at 189°F-192°F compared to the USDA recommended 165°F-180°F so we gave it an 8.8/10. The meat was very juicy but the lack of roasted aroma and crispy skin resulted in a 7.5/10 for taste from our chef.






- Function: Rotisserie
- Temperature: 350°F
- Cooking Time: 40m
- Convection: Yes
We’ve conducted our Whole Roasted Chicken test a great many times, and the Cosori wasn’t the only one with a high power output and powerful convection system. What set it apart was its rotisserie kit and function.
In addition, the large cooking chamber had more than enough space for a 3 lb chicken to rotate smoothly with a baking pan below to catch the drippings, unlike the Instant Omni Plus 18L. Everything together scored a whopping 8.9/10.
The oven took only 40 minutes to roast the chicken to a beautiful color. That was the fastest time we’ve had so far, earning it a perfect 10/10. The skin was mostly golden with some appetizing golden-brown color at the wings and the tips.
However, it seemed like the skin cooked a bit too quickly and the fat wasn’t fully rendered, so the skin wasn’t very crispy. Nonetheless, the skin still deserved an 8.5/10.
What impressed us most was the near-perfect doneness—9.9/10—in such a short amount of time. The chicken had no pink spots and a consistent internal temperature of 178°F-181°F. It was basically spot-on to the USDA’s 165°F-180°F recommendation.
Unfortunately, for some reason, the meat wasn’t as juicy as we had expected. Combined with the less-than-crispy skin, our chef couldn’t give the chicken a higher score than 8/10 after tasting it.
Baked French Fries




- Function: Bake
- Temperature: 400°F.
- Cooking Time: 25m 50s
- Convection: Yes
With a score of 5.6/10, the Black+Decker left a lot to be desired in the Baked French Fries test. In comparison, the same-sized Cosori CO130-AO did a much better job with its higher power output and air fry basket.
This oven took 25m 50s to bake 12 oz of fries which was just a bit too long over the limit of our Baked French Fries test. Thus, it failed our cooking time section. Coloring was uneven among the fries ranging from nicely golden to almost none so they could only get a 7/10.
The textures were also uneven and, worse, none was particularly good. The golden fries were only a little crispy and the ones that lacked color were soft. Overall, it was a 6.8/10 for this test.
Our chef gave the resulting fries a 7/10 for taste.




- Function: Bake
- Temperature: 400°F
- Cooking Time: 17m
- Convection: Yes
The Cosori took on our Baked French Fries test with its air fryer basket and scored an 8.1/10.
It took 17 minutes to bake 12 oz of frozen fries on tray level 2—quite fast compared to most. After comparing it with other units from our data, we gave it an 8.4/10 for cooking time.
The fries mostly had a great golden color with some of the thinner pieces looking the most appetizing. However, some thicker pieces weren’t as golden, so we gave the fries an 8/10 for color.
The same can be said about the texture of the fries, which earned another 8/10. Most of the fries were crispy on the outside and moist on the inside, but the thinner ones were a bit dry and the thicker ones weren’t crispy enough.
Overall, though imperfect, the fries were delicious enough to get one final 8/10 taste score from our chef.

Exterior




- Weight:12.9 lbs (5.8 kg)
- Length:19.3" (49.0 cm)
- Width:13.4" (34.0 cm)
- Height:10.6" (27.0 cm)
- Material:Stainless steel
- Color:Silver
- Door Handle:cool-touch
- Tray Indicators:No
- Crumb Tray:Slide-out
Despite its large size, the Black+Decker only has air ventilation holes around the side where the convection fan is. The two buffers on the back to keep the oven from being too close to the walls are quite sturdy. Also, a slide-out crumb tray is always a nice touch.
Our measurements of the oven’s footprint were 19.29" x 13.38" x 10.62" which were a lot different in terms of length and height compared to the manufacturer’s 22.8" x 13.4" x 15.5".






- Weight:15.7 lbs (7.1 kg)
- Length:20.0" (50.7 cm)

- Height:12.6" (32.0 cm)
- Material:Stainless steel
- Color:Silver
- Door Handle:Cool-touch
- Tray Indicators:No
- Crumb Tray:Removable
During our assessment, a prominent aspect of the Cosori toaster oven is the air ventilation holes on all sides of the casing to accommodate its powerful convection system. In addition, the glass door has indicators corresponding to the oven’s three tray levels and twelve cooking functions.
The oven doesn’t have carrying handles but it’s not heavy for its size so it’s not a big problem. Our measurements of 19.96" x 17.32" x 12.6" pretty much aligned with the manufacturer’s 20.1" x 16.5" x 12.5" with marginal differences being less than one inch. The difference in width is probably because we took the door handle into account.

Cooking Functions of the Black and Decker CTO6335S Digital Convection Toaster Oven

- Cookies
- Pizza
- Frozen snacks
- Potato
- Bake
- Broil
- Toast
- Bagel
The eight cooking functions are useful for beginners and experienced cooks can freely adjust the time and temperature of each to their liking.
- Toast (level 1-7)
- Bagel (level 1-7)
- Pizza (150°F - 450°F, 1 minute - 6 hours)
- Bake (150°F - 450°F, 1 minute - 6 hours)
- Roast (150°F - 400°F, 1 minute - 6 hours)
- Air Fry (150°F - 400°F, 1 minute - 6 hours)
- Broil (150°F - 450°F, 1 minute - 6 hours)
- Cookies (150°F - 450°F, 1 minute - 6 hours)
- Rotisserie (150°F - 400°F, 1 minute - 6 hours)
- Dehydrate (100°F - 180°F, 30 minutes - 24 hours)
- Ferment (80°F - 110°F, 30 minutes - 12 hours)
- Warm (140°F - 230°F, 1 minute - 12 hours)
Besides the basic cooking functions, which already have a wide time and temperature range, the Cosori air fryer toaster oven also has various practical additional cooking functions allowing for even wider time and temperature ranges.
The ones that impressed us the most were Warm, Dehydrate, and Ferment which can maintain the oven at as low as 140°F, 100°F, and 80°F respectively. Looking at a number of recipes, these temperatures fit their intended purpose, which means this oven can act as a family-sized dehydrator and dough proofer.
Note that only the bottom heating elements operate during these functions.
Interior



- Heating Elements:4 quartz
- Convection Fan:Yes
- Lighting:No
- Tray Levels:2
- Rotisserie:No
- Safety Hook:No
The Black+Decker only has two tray levels but you can make use of the flippable rack to effectively create two more levels. The oven has a convection system but no internal lighting—unlike the Ninja DT201—which can be an inconvenience considering the interior is black.
The oven has quartz heating elements that use infrared light to cook. They have their own safety guards to prevent direct contact with baking pans and trays.
Compared to the more common nichrome heating elements, they produce more heat and cool down faster. They are also more energy-efficient and easier to clean but don’t last as long in terms of durability. However, if grease splashes onto the heating elements while cooking, it’ll leave permanent stains.




- Heating Elements:4 nichrome
- Convection Fan:Yes
- Lighting:Yes
- Tray Levels:3
- Rotisserie:Yes
- Safety Hook:No
The interior features include a convection fan, light, a rotisserie socket and bracket, three tray levels, and four nichrome heating elements. To be nitpicky, we think it’s a shame it doesn’t have a non-stick coating, so it may accumulate some stubborn stains.
Capacity

- Length:14.2" (36.0 cm)
- Width:12.6" (32.0 cm)
- Height:7.9" (20.0 cm)
The CTO6335S can comfortably fit 6 slices of toast, a 12-inch pizza, and a 3 lb whole chicken. While the manufacturer didn’t state the oven’s capacity, we measured the cooking chamber’s volume to be around 23 liters.

- Length:14.2" (36.0 cm)
- Width:13.8" (35.0 cm)
- Height:9.8" (25.0 cm)
The Cosori has a spacious cooking chamber even compared to other large ovens. It can accommodate 6 slices of toast, a 13-inch pizza, or a 5-pound chicken.
We measured the volume to be around 31.49 liters compared to the manufacturer’s listing of 30 liters. The difference is minor and could just be a difference in measuring standards.
Power Cord the Black And Deck Convection Toaster Oven

- Length:24.8" (63.0 cm)
- Type:3-prong plug
- Power:1500 W
- Rated Output:120 V ~ 60 Hz
Even though the length of 24.8" is enough for household use, the power cord protrudes from the bottom of the oven reducing the usable length. In addition, it’s not long enough to wrap around the two back buffers.

- Length:40.9" (104.0 cm)
- Type:3-prong plug
- Power:1800 W
- Rated Output:120 V ~ 60 Hz
The power cord has plenty of length for household use—roughly 40.94 inches. It protrudes from the bottom of the oven, unfortunately, so it may create awkward kinks now and then.
Accessories

- Length:14.2" (36.0 cm)
- Width:10.0" (25.4 cm)
- Height:0.9" (2.2 cm)
- Material:Stainless steel
- Dishwasher Safe:Yes
The baking rack can be placed in the oven either way up, effectively adding two more tray levels for the oven.

- Length:14.2" (36.0 cm)
- Width:13.4" (34.0 cm)
- Height:0.3" (0.7 cm)
- Material:Stainless steel
- Dishwasher Safe:Yes
The baking rack fits perfectly onto its guide rails to prevent accidents when placing food in the oven. It’s also shaped to maximize the space inside the cooking chamber.
Accessories

- Length:13.3" (33.8 cm)
- Width:10.2" (25.8 cm)
- Height:1.2" (3.0 cm)
- Material:Stainless steel
- Dishwasher Safe:Yes
The baking pan is large and, being 100% compatible with the broiling rack, it catches all the drippings. This prevents any hot mess from dirtying the heating elements thus mitigating that potential fire hazard. However, it’s not 100% non-stick so you may have some stubborn stains to deal with after a heavy roasting session.

- Length:14.2" (36.0 cm)
- Width:11.8" (30.0 cm)
- Height:1.2" (3.0 cm)
- Material:Stainless steel
- Dishwasher Safe:Yes
The baking pan also fits the guide rails to fully utilize the cooking space. It has ridges and grooves which can give your food attractive roasting marks and allow drippings some space to flow away. Its coating isn’t completely non-stick, so it may gather some stubborn stains, though.
Accessories

- Length:11.7" (29.7 cm)
- Width:8.7" (22.0 cm)
- Height:0.7" (1.9 cm)
- Material:Stainless steel
- Dishwasher Safe:Not advisable
The broiling rack is designed to fit the baking pan perfectly while the holes are there to help with air circulation around the food. It doesn’t have a coating though so it may be prone to stains, caramelized bits of food, and discoloration.

- Length:14.0" (35.6 cm)
- Width:12.0" (30.5 cm)
- Height:0.8" (2.0 cm)
- Material:Stainless steel
- Dishwasher Safe:Not advisable
The crumb tray is a helpful accessory to clean up the pesky falling crumbs and bits. However, some may still fall to the oven’s floor as the tray is removed.
Build Quality

The Black+Decker CTO6335S is equipped with a tamper-resistant screw to prevent removal of the outer cover. However, the bottom tray can easily slide out and the door can also open if you tilt the oven.
Throughout our tests, we noticed that the oven’s large capacity is somewhat counteracted by its power output of 1500 W. We speculated on its ability to perform more efficiently if it were 1800 W.

The Cosori is made from high-quality and durable 304 stainless steel. The thick casing provides good insulation in addition to a well-thought-out convection system. Thus, the oven only gets hot to the touch after a long cooking time at a high temperature (>400°F).
As for the control panel, the LED display is very easy to see, the control dials turn smoothly, and the buttons are responsive. The accessories are designed to make the most out of the cooking chamber’s interior space.

- Cleanability (20%)6.0/10
- User Control (30%)9.5/10
- Ease of Use (50%)8.0/10
- Cleanability (20%)7.5/10
User Control
The Black+Decker has 8 functions but the convection toggle is only applicable to Bake. There’s an indicator light for when a function starts and stops — which are two separate buttons on the control panel.
For all functions except Toast and Bagel, you can push the increment and decrement buttons once to change the temperature in increments of 5°F and hold to change in increments of 25°F. After pressing the Timer button, the same goes for cooking time but in increments of 1 minute and 10 minutes. For Toast and Bagel, simply choose a level from 1 to 7.
Unfortunately, even though the label shows a stay-on function, we couldn’t find it in the control panel or the user manual. A small thing we didn’t like about the buttons was that they sometimes didn’t respond well.
The convection feature can toggle between normal and high, and neither setting makes much noise. The fan can run on all functions except Toast and Bagel.
Since time and temperature are controlled by a single dial, you must toggle between functions. Press the dial’s face to switch between them. Temperature can be adjusted in increments of 5°F or 2°C-3°C.
The timer, however, has different steps depending on the cooking function. For Pizza, Bake, Roast, Air Fry, Broil, Cookies, Rotisserie, and Warm functions, the timer can be adjusted in increments of 1 minute until it reaches 60 minutes, then in increments of 5 minutes from 1-2 hours, in increments of 10 minutes from 2-3 hours, and in increments of 15 minutes from 2-3 hours. For Dehydrate and Ferment functions, the timer only adjusts in increments of 30 minutes.
On top of the many practical cooking functions, the ease with which you can adjust time and temperature makes this oven, overall, simpler to use than many other digital ones. In addition, you can press and hold the time and temperature dial to turn off the display to save energy while you’re not cooking.
Ease of Use
For all functions except for Toast and Bagel, the Black+Decker has an automatic preheat feature. This will always heat the heating elements to 350°F, which takes around 4m 20s, before starting the actual timer. Then, the internal temperature will gradually stabilize around your input temperature.
One thing to note is that you cannot change the temperature or time during the automatic preheat cycle. You can only do so once the oven reaches the selected temperature.
Keep in mind that the oven’s exterior gets hot to the touch quite quickly. In addition, it doesn’t turn off upon opening the door, unlike some others. The door also can’t be opened partially.
This oven beeps with each push of a button and does so three times when it finishes cooking. The oven always remembers the last selected setting until it’s unplugged. It’s advised to unplug the oven after you finish using it as the digital display doesn’t turn off after a period of no interaction.
The Cosori has an automatic preheat phase which engages for the Pizza, Bake, Roast, Broil, Cookies, and Air Fryer functions. If the oven’s already hot, the function will recognize that fact and reduce its preheating time.
This toaster oven is one of the rare units that actually preheat to the input temperature. Most others simply heat to a hardwired preheat temperature that cannot be adjusted.
According to our observation, the Cosori takes around 2-4 minutes to reach 300°F, 3-5 minutes for 325°F, 4-6 minutes for 350°F, and 6-8 minutes for 400°F. When preheating is finished, the oven will beep several times and the display will flash once every minute. You’ll need to press start to initiate cooking or the cooking function will be canceled after 10 minutes.
Thanks to the light toggle button, you have full control over when to turn the light on and off. The door can rest open at a 70° angle to allow food to cool inside the oven. Opening the door doesn’t stop the heating elements or the interior light.
The oven turns off automatically after 30 minutes of no interaction. Nonetheless, we still suggest unplugging it after use for safety reasons.
The Cosori’s EvenRapid Tech™ is advertised to reduce cooking time by 30% thanks to increased heat circulation. Suffice to say, it met our expectations with fast cooking times and even surface caramelization (except on our Pizza test).
Cleanability




We cleaned the Black+Decker following our toaster oven cleaning guide. With the oven having an internal and external coating, cleaning was quite straightforward.
However, even with the slide-out crumb tray, we still had to tilt the oven to get all of the crumbs out. In addition, some of them got stuck inside the heating element safeguards and we had no way of getting them out.





The Cosori’s exterior and interior are made of stainless steel, so they’re usually easy to clean. However, the interior doesn’t have a non-stick coating, so the grease from our whole roasted chicken test led to some extremely stubborn stains on the cooking chamber’s ceiling. We couldn’t completely remove them even after brushing them with a paste of baking soda and water.
The rotisserie forks and rod as well as the rotisserie bracket and the baking pan developed equally stubborn stains. On the bright side, it wasn’t difficult to clean caramelized bits of food from the air fryer basket despite the fishnet design.
The grease on the other walls and around the fan cavity was easy to clean. We were worried that grease might splash into the fan cavity, though.
We were able to easily remove fallen food scraps thanks to the removable crumb tray. However, we still had to tilt the oven to get them all out.
