• Usoraszkt 3.81Qt — biggest strength: A 3.81-quart borosilicate glass cylinder with 360° viewing, a nonstick interior, and eight presets (including a dedicated sweet potatoes setting) in a compact 9.84"D x 9.84"W x 12.6"H footprint.
• Usoraszkt 3.81Qt — biggest trade-off: Its capacity is the smaller of the two, and the internal figures list 4.2 liters, so heavier batches of sweet potato cubes may need a second round.
• MuChaIOAK Glass Airy Fryer — biggest strength: A larger 4.44-quart bowl (listed as 4.2 liters internally), a stainless steel grill for even hot-air circulation, a comfort handle, and a 31.5-inch power cord.
• MuChaIOAK Glass Airy Fryer — biggest trade-off: It's wider than the Usoraszkt unit and the dishwasher-safe claim applies only to the glass pot, not the whole appliance.
• Who each pick is for: Choose Usoraszkt 3.81Qt for a tight countertop and simple sweet potato tasks; choose MuChaIOAK Glass Airy Fryer for bigger batches, easier cord routing, and a wider transparent bowl.
The Usoraszkt 3.81Qt is a 1200W glass-cylinder air fryer built around a clear borosilicate pot. You can watch sweet potato cubes brown from every angle without pulling the basket, which matters because opening the appliance mid-cook releases heat and can leave pieces uneven. The touchscreen with digital display shows temperature, time, and cooking progress at a glance, so you can set 176°F to 392°F and 1 to 60 minutes and walk away.
What it does best is simplicity. The eight presets cover french fries, roast, chicken wings, egg tarts, grilled fish, sweet potatoes, grilled shrimp, and steak, each with a default reference temperature and time you can then adjust. For air fryer sweet potatoes specifically, that dedicated preset plus the 360° glass view is a genuinely useful pairing — you can nudge the time up or down while watching the cubes crisp. The 1200W rapid air circulation is rated to reach cooking temperature quickly, which shortens the wait before your first batch.
Who should buy it: anyone cooking for one or two, or making snacks for a few friends, who wants a compact black unit with a nonstick glass interior that's easy to wipe down. Who should skip it: if you regularly cook large sweet potato batches for a bigger family, or you want the extra bowl room and cord length, the MuChaIOAK model fits better. And if cabinet space is tight in a way that favors a taller, narrower cylinder, the Usoraszkt's 12.6-inch height is the spec to check against your shelf.
The MuChaIOAK Glass Airy Fryer matches the Usoraszkt on the core engine — 1200W, rapid air circulation, 176°F to 392°F, 1 to 60 minutes, and the same eight presets — but wraps it in a larger transparent bowl. The listed capacity is 4.44 quarts (internally noted as 4.2 liters), so it handles more sweet potato cubes or fries in one go before you'd need a second round. The stainless steel grill sits under the food to let hot air circulate evenly, which is the mechanism that keeps cubes from steaming on one side.
The details here lean toward convenience. The comfort-designed handle gives you a firm grip when sliding the glass pot in and out, and the 31.5-inch power cord lets you place the unit further from the outlet without an extension cord cluttering the counter. The touchscreen with digital display works the same way as the Usoraszkt's: tap to set temperature, time, and function, and read the current settings and progress at a glance. Only the glass pot is dishwasher safe, so plan on hand-washing the grill and housing.
Who should buy it: households cooking larger portions, anyone who wants more room for a full tray of sweet potato fries, and cooks who value flexible placement thanks to the longer cord. Who should skip it: if you want the narrowest possible footprint, note this model is listed at 12.6 inches wide and 9.84 inches tall — wider, not taller, than the Usoraszkt. If you prefer a black appliance, it's also worth confirming the finish, since the spec sheet lists the color as white.
Side-by-Side: Which Should You Choose?
• Best for smaller kitchens and tighter shelves → Usoraszkt 3.81Qt: its 9.84-inch width and 12.6-inch height give it a narrower counter footprint.
• Best for larger sweet potato batches → MuChaIOAK Glass Airy Fryer: the 4.44-quart bowl beats the Usoraszkt's 3.81 quarts.
• Best for a nonstick, easy-clean interior → Usoraszkt 3.81Qt: its inner material is listed as nonstick glass, which simplifies cleanup after sweet potato cubes.
• Best for flexible counter placement → MuChaIOAK Glass Airy Fryer: the 31.5-inch power cord reaches further than a standard short cord.
• Best for a black finish → Usoraszkt 3.81Qt: the color is listed as black, while the MuChaIOAK is listed as white.
• Best for a dedicated sweet potato preset on both → tie: both offer the same eight presets and the same 176°F–392°F range, so the difference comes down to bowl size and cord, not cooking modes.
In my opinion, most people shopping this pair for air fryer sweet potatoes should pick the MuChaIOAK Glass Airy Fryer. The larger bowl means fewer repeat batches of sweet potato cubes, the stainless steel grill supports even browning, and the longer power cord makes real-world placement easier. I'd choose the Usoraszkt 3.81Qt instead if counter space is the deciding factor or you specifically want the black finish and nonstick glass interior. Both share the same 1200W engine, presets, and temperature range, so the choice is really about size, color, and cord length. Check the current price on Amazon before you commit, since that's the one factor that can tip a close call.
how to air fryer sweet potatoes
Peel or scrub the sweet potatoes, cut them into even pieces, and toss lightly with oil. Use the sweet potatoes preset on either fryer as your starting reference, then adjust time between 1 and 60 minutes and temperature between 176°F and 392°F. Watch through the 360° glass pot and stop when the edges brown.
how to air fryer sweet potato cubes
Cut the sweet potatoes into roughly equal cubes so they cook at the same rate. Spread them in a single layer — the MuChaIOAK's larger 4.44-quart bowl handles more cubes at once, while the Usoraszkt's 3.81 quarts suits smaller batches. The stainless steel grill on the MuChaIOAK is designed to circulate hot air evenly around each cube.
how to air fryer sweet potato fries
Slice the sweet potatoes into fry-shaped strips and keep them uniform for even crisping. Both fryers offer a french fries preset plus a 176°F to 392°F range, so start there and adjust. Avoid opening the pot mid-cook; the 360° transparent bowl lets you check progress without releasing heat.
how to air fryer sweet potato whole
Whole sweet potatoes take longer than cubes or fries, so use the full timer range and start at a moderate temperature before finishing higher. Prick the skin so steam escapes. Both models run 1 to 60 minutes, so check doneness through the glass and add time as needed rather than guessing.
