A 4-in-1 microwave combines everyday microwave cooking with additional functions such as air frying, convection baking, and combination cooking. The Toshiba 1.5-cubic-foot model is best for buyers who want those four functions in a larger listed capacity; the BLACK+DECKER is better for a compact footprint and extra roast capability. The other picks add air-fry and convection options, though their listed features do not all describe the same four-function setup.

| GE GCST10A1WSS | Air frying and convection | Microwave, air fry, convection |
TOSHIBA 1.5 Cu.Ft 4-in-1 Microwave
Best for: Buyers who specifically want a four-function microwave with more listed interior capacity. This 1.5-cubic-foot model offers microwave, air-fry, convection, and combination cooking, with 1000 watts of microwave power.
Its combination mode uses microwave and convection cooking together. The feature list also identifies auto bake, defrosting, auto roast, and sensor menus for popular foods such as frozen pizza and vegetables. Those presets may help shoppers who prefer guided cooking rather than choosing every setting manually.
Why it stands out: The four core functions are clearly named, making this a direct match for a search for a 4-in-1 microwave. Limitation: The listed information does not give the unit’s external dimensions, so measure counter space before choosing it.
BLACK+DECKER 5-in-1 Microwave Air Fryer
Best for: Shoppers looking for a compact 0.9-cubic-foot appliance with several cooking modes and air-fry presets. Its five listed functions are microwave, air fry, combination cooking, bake, and roast. Microwave output is 900 watts.
The model includes 10 cooking levels, seven automatic microwave menus, and 11 air-fry presets. The listed air-fry menu examples include fries, chicken wings, fish, vegetables, and spring rolls. That preset selection makes it a practical option for households that often prepare frozen snacks or want shortcut settings.
Why it stands out: It adds roast to the familiar microwave, air-fry, bake, and combination functions. Limitation: Its listed capacity is smaller than the 1.5-cubic-foot Toshiba, so it may be less suited to buyers prioritizing a larger cavity.
TOSHIBA 1.0 Cu.Ft 8-in-1 Combo
Best for: Buyers who want more cooking modes than a basic 4-in-1 setup and prefer a 1.0-cubic-foot model. The listed functions include microwave, air fry, convection bake, broil, combination cooking, low-temperature cooking, odor removal, and defrost.
The feature list describes this as an 8-in-1 appliance and highlights air frying as a way to make crisp-style foods with less fat than traditional frying. It also has a two-step child lock, which is relevant for homes where preventing unintended operation is a priority.
Why it stands out: Its broader set of named modes may suit cooks who want broiling and odor removal as well as the usual air-fry and baking options. Limitation: It has less listed capacity than the 1.5-cubic-foot Toshiba, and the extra modes may be unnecessary for buyers seeking only four basic functions.
TOSHIBA OptiChef PRO MAX Air Fryer Combo
Best for: Shoppers who value an on-screen interface and air-fry-style cooking. This 1.3-cubic-foot model has 1100 watts of listed power, a 2.4-inch color screen, and a responsive interface intended to make cooking tasks easier to operate.
Its ChefFry Plus feature uses a top fan and heating element to replicate an air fryer oven. A built-in humidity sensor is listed as a feature for helping heat food evenly and retain moisture. These details make it a different kind of pick from models whose product information spells out a traditional four-function lineup.
Why it stands out: The screen, air-fry system, and humidity sensor are its distinguishing listed features. Limitation: The supplied feature information does not enumerate four specific cooking modes, so verify that its functions match your needs before treating it as a direct 4-in-1 substitute.
GE GCST10A1WSS Microwave With Air Fry
Best for: Buyers comparing microwave models with both air-fry and convection features. The GE offers a 1.0-cubic-foot capacity and 1,050 watts of cooking power. Its listed dimensions are 13.98 inches wide, 9.49 inches high, and 13.23 inches deep.
The feature list says it includes a stainless-steel crisper pan for air frying and a wire rack for convection cooking. The convection function circulates hot air around food, according to the product information, and is intended for browning and smaller baked goods.
Why it stands out: The listed accessories and stated dimensions give buyers practical details for evaluating cooking and counter fit. Limitation: The supplied information lists microwave, air fry, and convection features but does not identify a fourth cooking mode; choose it for those named functions rather than assuming it matches a 4-in-1 configuration.
Buying Guide: How To Choose A 4-in-1 Microwave
Which cooking functions do you need?
Compare the actual modes, not only the “4-in-1” label. The Toshiba 1.5-cubic-foot model explicitly lists microwave, air fry, convection, and combination cooking. Other models may add bake, roast, broil, or sensor features, while product descriptions may use different names for similar cooking approaches. Confirm that the appliance includes the functions you expect to use.
How much capacity and counter space do you have?
Capacity can affect what you can fit inside, while exterior dimensions determine whether the appliance fits your counter. Among these picks, listed capacities range from 0.9 to 1.5 cubic feet. The GE listing supplies exterior measurements; the other supplied product details do not. Check the full product specifications and leave any required clearance around the appliance.
Do wattage and presets matter?
Listed microwave power ranges from 900 watts on the BLACK+DECKER to 1100 watts on the Toshiba OptiChef PRO MAX. Power is only one comparison point: cooking modes and controls also matter. Presets can simplify common foods, while manual settings may suit buyers who prefer more control. Check the instructions for cookware and food-specific guidance.
What accessories or safety features are included?
Look for accessories that support your intended cooking. The GE listing names a crisper pan and wire rack; the Toshiba 8-in-1 listing names a two-step child lock. Do not assume accessories, safety features, or cooking modes are included unless they appear in the product information.
