• ZhenD Toaster Oven Replacement — biggest strength: a complete 3-in-1 set (air fryer basket, baking tray, wire rack) sized at 12.3" x 12.3" x 1.3" to fit Gourmia GTF7655, GTF7530, GTF7460 and GTF7465 24L models snugly, with no wobble.
• ZhenD Toaster Oven Replacement — biggest trade-off: it is a replacement part, not an appliance. It only works if you already own one of those four Gourmia ovens, and it has no heating element, no controls and no presets of its own.
• HZOPUTLH 1200W — biggest strength: a self-contained 1200W air fryer with a 4.44Qt borosilicate glass pot you can watch from any angle, eight one-touch presets (sweet potatoes included) and adjustable time and temperature from 1–60 minutes and 176–392°F.
• HZOPUTLH 1200W — biggest trade-off: it is a single-purpose countertop appliance, so if you already own a working Gourmia oven, this duplicates rather than repairs what you have — and only the glass pot is dishwasher safe.
• Choose ZhenD Toaster Oven Replacement if your Gourmia 24L oven still works but the accessories are worn, bent, stained or missing.
• Choose HZOPUTLH 1200W if you want to air fry sweet potatoes, wings or fries from scratch on your countertop with nothing else required.
This is a repair-and-restore purchase, and I mean that literally. ZhenD built this kit around four specific Gourmia 24L French-door digital air fryer ovens: the GTF7655, GTF7530, GTF7460 and GTF7465. Every piece measures 12.3" x 12.3" x 1.3", which is the detail that matters most. A basket that slides around mid-cook is annoying at best and a tipping hazard at worst, so a snug, stable fit is the entire point of buying a purpose-made set instead of a generic pan that happens to be roughly the right size.
What you get is three pieces covering three jobs. The air fryer basket handles crisping — sweet potato cubes, french fries, chicken wings. The baking tray takes pastries and anything you want to slide in and out flat. The wire rack lifts food for roasting vegetables or grilling. Together they let you use the oven's 17 presets the way they were designed to be used, rather than improvising with foil and a sheet pan. Construction is heavy-duty food-grade steel, described as odor-free, non-toxic and BPA-free, and ZhenD states all three parts resist rust and staining even after repeated high-heat use. The whole set weighs 2.35 pounds.
Who should skip it: everyone else. If your oven is a different brand, a different size or not a 24L French-door model, this set is not for you — the 12.3" square footprint is not universal. And if you do not own a countertop oven at all, this kit is useless on its own. It cannot heat anything. It has no cord, no element, no display. You would be buying three metal objects and a very specific dream.
HZOPUTLH 1200W: Who It's For
The HZOPUTLH 1200W is the opposite proposition: everything you need in one box. A 1200W heating system, a 4.44Qt borosilicate glass pot, a stainless steel grill, a digital touchscreen and eight presets — french fries, roast, chicken wings, egg tarts, grilled fish, sweet potatoes, grilled shrimp and steak. You set time anywhere from 1 to 60 minutes and temperature from 176 to 392°F, or just tap a preset and walk away.
The glass pot is the feature I keep coming back to, because it changes how you cook. A 360° viewable borosilicate pot lets you watch browning from every angle without pulling the basket out and dumping heat into the room. For sweet potatoes specifically, that matters: the window between "perfectly caramelized" and "charred beyond recognition" is short, and being able to see it happen is genuinely useful. The trade-off is weight and material — at 7.1 pounds with a glass body, this is not a featherweight, and glass asks for more careful handling than a metal drawer. Only the glass pot is dishwasher safe; the rest is a hand wash.
Capacity is 4.44Qt, which HZOPUTLH frames for small families or groups of friends — enough for a main and a side without running two batches. The compact 9.84" x 9.84" x 12.6" cylinder footprint suits apartments, dorms and small kitchens, and the brand also lists camping and food stalls as intended settings. It runs on 110V US standard power, arrives assembled, and ships with the air fryer, the grill and an English manual.
Who should buy it: anyone who wants sweet potato fries, wings or roast vegetables with less oil and no separate oven required. Who should skip it: anyone whose Gourmia oven is fine and just needs new accessories — this would be a redundant second appliance, and a glass-bodied one at that.
Side-by-Side: Which Should You Choose?
• You want to air fry sweet potatoes without owning any oven → HZOPUTLH 1200W. It has a dedicated sweet potato preset and its own 1200W element.
• You want a one-touch preset for sweet potatoes, wings, shrimp or steak → HZOPUTLH 1200W, which covers all eight.
• You need to bake pastries or use a wire rack for roasting inside an existing oven → ZhenD Toaster Oven Replacement, because the tray and rack are the point.
• You want to watch food brown without opening the appliance → HZOPUTLH 1200W with its 360° glass pot. No comparable feature exists on the ZhenD set.
• You want the lightest, simplest purchase → ZhenD Toaster Oven Replacement at 2.35 pounds versus 7.1 pounds for the glass air fryer.
• You want the most versatile cook-it-yourself option for a small kitchen → HZOPUTLH 1200W — roasting, grilling, baking and air frying in one compact cylinder.
• You want easy cleanup after high-heat cooking → ZhenD Toaster Oven Replacement, where all three parts resist rust and staining; on the HZOPUTLH only the glass pot goes in the dishwasher.
In my opinion, the honest answer is that most people searching this comparison should buy the HZOPUTLH 1200W — because if you are asking how to air fryer sweet potatoes, you probably want an appliance that cooks, not a set of trays for an oven you may not own. The glass pot, the sweet potato preset and the 176–392°F range make it a complete, self-sufficient kitchen tool. I would only steer you to the ZhenD Toaster Oven Replacement if you specifically own one of those four Gourmia 24L models and need to bring it back to life. Buy for the oven you actually have, not the one you might.
how to air fryer sweet potatoes
On the HZOPUTLH 1200W, tap the sweet potato preset and let the 1200W element do the work, adjusting time anywhere from 1 to 60 minutes and temperature between 176 and 392°F. The 360° glass pot lets you watch them without opening the appliance and losing heat. If you are using a Gourmia oven instead, the ZhenD basket is what you would cook them in.
how to air fryer sweet potato cubes
Cubes need airflow on all sides, which is exactly what the ZhenD air fryer basket and the HZOPUTLH grill insert are for. On the HZOPUTLH, spread them in a single layer in the 4.44Qt pot and set a temperature in the 176–392°F range, checking through the glass rather than opening it.
how to air fryer sweet potato fries
Both products cover this. The ZhenD set lists crisping french fries among its uses inside a Gourmia 24L oven, and the HZOPUTLH has a dedicated french fries preset plus a 4.44Qt pot sized for a small family's worth in one batch.
how to air fryer sweet potato whole
A whole sweet potato is the one case where the glass pot wins clearly — you can watch it through the 360° viewable borosilicate glass and adjust the 1–60 minute timer as it cooks. The ZhenD wire rack can hold one in a Gourmia oven, but you would be relying on that oven's own presets, not the accessory set.
