COSORI 26.4QT Air Fryer Toaster Combo Review [Model: CS100-AO]

COSORI CS100-AO is an air fryer with 26.4-quart cooking capacity with temperature range of 80°F to 450°F (most air fryers only go as high as 400°F). COSORI is one of the most popular air fryer manufacturers so is the CS100-AO as good as you would expect?


COSORI CS100-AO cooks food well and everything comes out delicious however there are some nuances.

First, it does require preheating. It doesn’t take more than few minutes but some air fryers doesn’t require that (those are typically smaller sized basket air fryers).

Second, if you are cooking something very large or oven is full of food it might not cook perfectly even. This usually doesn’t happen often but since it might it must be mentioned.

Third, food comes out crispy but you might expect more crispiness. This can be easily solved by spraying a little bit of oil on food before cooking it.

Fourth, it does emit some heat but not as much as full-sized oven. Front glass tends to get hot and some of the housing might too.

Fifth, it’s also is a bit louder than air fryers typically are. It’s not super loud but be aware it’s not the quietest air fryer out there.

Despite these flaws it’s still a pretty good air fryer. It does cook well and food does come out tasting great which is the most important thing. Since COSORI CS100-AO offers quite a lot for its price it can still be considered a good air fryer despite the fact it’s not perfect (but nothing really is).
