• YSHUSTGY 3.81Qt — biggest strength: A 1200W rapid-heat element plus a 360° borosilicate glass pot, so you can watch sweet potato cubes brown without opening the basket and losing heat.
• YSHUSTGY 3.81Qt — biggest trade-off: The 3.81-quart pot and 176°F–392°F range leave less headroom for large batches or very high-heat finishing.
• LDAILY 4.7 — biggest strength: A 4.7-quart glass basket with a steam-frying mode, adjustable "juicy" function and a 180°F–400°F range — designed for tender-inside, crisp-outside results with minimal oil.
• LDAILY 4.7 — biggest trade-off: At 1000W it heats more gently than the YSHUSTGY, and the steam mode adds a water-fill step plus a tank to empty and clean.
• Who each pick is for: Small kitchens, singles and couples doing quick sweet potato cubes → YSHUSTGY 3.81Qt. Small families or anyone who wants whole baked sweet potatoes with a soft center → LDAILY 4.7.
The YSHUSTGY 3.81Qt is built around speed and visibility. Its 1200W element and rapid-heating technology are meant to cut preheat time, and the touchscreen with digital display lets you set temperature and time in a few taps. For sweet potatoes specifically, there's a dedicated preset, so you can drop in cubes or thin wedges, tap once, and let the default reference temperature and time do the work. You still have full manual control from 1 to 60 minutes and 176°F to 392°F if you want to push browning further.
The clear borosilicate glass pot is the real differentiator here. Because the pot is 360° viewable, you can track how dark your sweet potato edges are getting without lifting the lid — and not opening the basket matters, since every open causes heat loss that leads to uneven cooking and longer times. The stainless steel grill underneath lets hot air circulate around the food, which is exactly what you want for cubed sweet potato that would otherwise steam and go soft on one side. Materials are PP, borosilicate glass and stainless steel, and only the glass pot is dishwasher safe.
LDAILY 4.7: Who It's For
The LDAILY 4.7 is the more feature-rich of the two, and its headline trick is steam frying. It combines a steam mode with 360° hot air circulation, and the brand claims up to 95% less oil than traditional frying. The adjustable juicy function is meant to keep food tender inside while the exterior crisps — which is precisely the challenge with whole sweet potatoes and thick-cut sweet potato fries, where the middle can stay hard while the outside burns. You fill water below the max line for juicy mode, and the brand notes a 30-minute max juicy setting for the most succulent results.
The basket is high borosilicate glass, BPA-free, PTFE-free and PFAS-free, and it's transparent so you can monitor food without opening it. Six one-touch presets cover fries, chicken, steak, seafood, sweet potatoes and nuts — a sweet potato preset plus real manual range from 180°F to 400°F in 5°F increments, a 1–60 minute timer, and automatic pause/resume. The 4.7-quart basket holds more than the YSHUSTGY, and the removable basket and crisper plate are both dishwasher safe, which matters after sticky sweet potato glaze.
Safety and upkeep are spelled out: overheat protection, ETL certification, a requirement to keep the unit at least 6 inches from walls, a 10-minute empty run before first use, and instructions to empty and clean the water tank after use. Who should buy it: couples and small families, or anyone who wants whole baked sweet potatoes and larger batches with a softer interior. Who should skip it: people who want the simplest possible routine — the water fill, tank cleaning and 30-minute cool-down before cleaning add steps the YSHUSTGY doesn't have.
Side-by-Side: Which Should You Choose?
• Best for fast preheat and quick small batches → YSHUSTGY 3.81Qt. Its 1200W element is the higher-powered of the two.
• Best for larger portions and whole sweet potatoes → LDAILY 4.7. The 4.7-quart basket beats the 3.81-quart pot on volume.
• Best for juicy interiors on thick cuts → LDAILY 4.7. Steam frying plus the adjustable juicy function is designed for exactly that.
• Best for higher-heat finishing → LDAILY 4.7. It reaches 400°F versus the YSHUSTGY's 392°F, and adjusts in 5°F steps.
• Best for small counters → YSHUSTGY 3.81Qt. Its 9.84 x 9.84 x 12.6-inch body is the more compact of the two.
• Best for easy cleanup → LDAILY 4.7. Both glass pots are dishwasher safe, but the LDAILY's crisper plate is dishwasher safe too.
• Best for preset variety → YSHUSTGY 3.81Qt. Eight presets versus six, including egg tarts and grilled shrimp.
In my opinion, the LDAILY 4.7 is the better buy for sweet potatoes. The combination of a steam-frying mode, an adjustable juicy function, a 4.7-quart glass basket and a 400°F ceiling is a closer match to how sweet potatoes actually behave — they need moisture inside and heat outside, and they take up space. I'd recommend the YSHUSTGY 3.81Qt instead if you cook for one or two, want the fastest preheat, and value a compact footprint over capacity. Either way, check the current price on Amazon before deciding, since that's the one variable that can flip this call.
how to air fryer sweet potatoes
Peel or scrub them, cut into even pieces, toss with a little oil, and cook in a single layer. Both units have a sweet potato preset — the YSHUSTGY's default reference settings run within its 176°F–392°F range, and the LDAILY's preset sits inside its 180°F–400°F range. Shake the basket partway through for even browning.
how to air fryer sweet potato cubes
Cut into roughly equal cubes so they finish at the same time, and keep them in one layer — this is where the LDAILY's 4.7-quart basket helps. The YSHUSTGY's 360° glass pot lets you watch the edges darken without opening it, which prevents the heat loss that causes uneven cooking. Both offer a 1–60 minute timer.
how to air fryer sweet potato fries
Cut fries evenly and avoid overcrowding; thinner fries crisp faster than thick-cut ones. For thick-cut fries, the LDAILY's steam frying mode and juicy function are designed to keep the interior tender while the outside crisps, using up to 95% less oil. With the YSHUSTGY, stay within 392°F and shake the basket for even results.
how to air fryer sweet potato whole
Whole sweet potatoes need the most time and the most room, so the LDAILY 4.7's larger basket and 400°F maximum are the safer fit. Prick the skin, place them in the basket without stacking, and use the sweet potato preset. If you use juicy mode, fill water below the max line and remember the brand's 30-minute max juicy setting.
