Now, let’s take a closer look at the best-heated lunch boxes on the market.

1. WisaKey Electric Lunch Box

WisaKey 100W Electric Lunch Box Food Heater

The WisaKey 100W Electric Lunch Box Food Heater has a lot going for it. For starters, the unit is built with robust, food-grade materials that should keep the contents inside from spilling. Moreover, thanks to its sturdy base, the unit can double up as a plate when you’re eating while traveling, too.

Notably, the WisaKey heated lunch box can be powered by a variety of inputs. To that end, it supports 110V and 220V for home/office use. Additionally, it can be hooked up to your car’s 12V/24V port, too. Further, the unit comes with a 304 stainless steel container, which will keep your food warm and toasty for hours at an end.

We should add that the WisaKey Electric Lunch Box is adequately spacious at 1.8L. Correspondingly, you should be able to pack a healthy and filling home-cooked meal for work and travel. The icing on the cake is that the unit also comes with a free spoon and fork, thereby ensuring you have cutlery when you’re on the move.

Additionally, the company also bundles an insulated bag with your purchase. To no one’s surprise, the heated lunch box has received a slurry of positive reviews, with most buyers citing that it keeps the food warm and maintains the dish’s flavor.

2. Aotto Portable Oven

Aotto Portable Oven

Aotto’s Portable Oven doesn’t come with nearly as many accessories as WisaKey’s Electric Heated Lunch Box. On the flip side, Aotto’s contender promises supremely fast heating times, thanks to the oven’s 80W efficient heating. The unit can also fit most microwaveable, flat-bottom containers.

Aotto’s Portable Oven is backed by 80W conduction heating tech to bring your food to the ideal temperature. In fact, the company cites that the unit can heat food up to 168 degrees, and it can retain the temperature for hours at a stretch. As such, if you’re a slow eater, your food will not go cold if you don’t gobble it up in minutes.

Additionally, the company claims that it can warm up food from room temperature to 158 degrees in about an hour. Refrigerated dishes may take longer, at 1.5 hours, though. Since we’re on the subject, you should note that it only comes with a heating plate. As such, you’ll have to buy separate utensils or wrap your food in aluminum foil to warm it up.

While all that’s good and dandy, the unit also comes with an insulated cover of sorts that has front pockets to store your cutlery. If anything, the device requires a 110V outlet for power, so it isn’t as versatile as WisaKey’s Electric Lunch Box.

What We Like

  • Affordable
  • Quite capacious
  • Easy to use

What We Don’t Like

  • Doesn’t come with cutlery
  • Limited power options

3. TRAVELISIMO Electric Lunch Box

TRAVELISIMO Electric Lunch Box

TRAVELISIMO Electric Lunch Box strikes the perfect balance between the aforementioned alternatives. To that end, the unit also comes with 80W heating, which, per the brand, should warm up a delicious home-cooked meal in under 30 minutes.

At the same time, TRAVELISIMO’s Lunch Box can be plugged into a 12V/24V car socket or a 110V outlet as well. As such, you can use the device when you’re on the go or in an office setting. We should also add that the unit offers oodles of storage to pack your favorite meals.

In fact, the portable heated lunch box comes with two compartments with 1.5L and 0.45L capacities, respectively. Consequently, you can separate some of your meals and ensure the flavors don’t go astray.

We should also add that the device comes with a 304 stainless steel tray, so you don’t have to buy a separate utensil to heat up your food. Additionally, your purchase comes with a stainless steel fork and knife set, as well as various power cables to plug in the device to an AC outlet or your car’s charging socket. Unsurprisingly, buyers can be seen singing praises of the heated lunch box, with most citing that it works as advertised.
