How Do You Choose a Portable Food Warmer?
Here are the most important features to check before you buy a portable oven:
1. Size and capacity – make sure the size and capacity fit a good-sized meal
2. Container material – choose nontoxic containers (preferably glass/stainless steel) to ensure food safety. Some food warmers come with a container and some don’t, so you’ll have to find a right-size heat-resistant container to place inside.
3. Power plugs – some mini ovens can be plugged in a car/truck, some can only be used with a 110/120V, and some come with both plugs for multi-use.
4. Price and warranty – portable food warmers’ price range is about $29 – $39, depending on what’s included inside (containers/spoons/forks), power plugs, and brand reputation.
The 6 Best Portable Food Warmers
20 minutes before you want to eat you plug it in and it heats your food up perfectly. Here are the 6 best electric lunch boxes of 2022:
1. Hot Logic Mini Portable Oven (120V) – Best for Work
- Size – 8.75″ x 6.75″ x 2.5”
- Weight – 1 pound (lightweight!)
- Containers – any flat and heat-resistant container (not included)
The Hot Logic portable oven and food warmer can cook your food (even frozen food) evenly or just warm it – without drying or burning it – for up to 1.5 hours.
It will also keep it warm (at 165 F) for 12 hours.
It works with a 120V plug, but buyers told us that if you want to use it in your car – just get a 75W power inverter (that will work even if the car is not running).
You won’t need to monitor your food. You just place your meal inside, plug it in, and come back when you are ready to eat it.
The heating plate can get up to 200 F and uses only 0.11kWh of electricity over a 3-hour use (without releasing any smells while heating!).
The Hot Logic food light and compact warming tote comes in 9 beautiful colors to choose from and is a highly rated, fantastic, and reliable little meal helper.
Consumers recommend searing/browning your meat before placing it inside it.
2. Travelisimo Electric Lunch Box (110V/12V/24V) – Best for Travel
- Size – 10″ x 8″ x 5″
- Weight – 2.37 pounds
- Containers – stainless steel, included
- Capacity – 1.5 L
The Travelisimo 3-in-1 electric lunch box is the only one that has 110V, 12V, and 24V – which means you can use it anywhere you go, including driving (car/truck), at the office, at school, on picnics, when camping, and for fieldwork.
The upgraded 60W model will heat your food in 20-30 minutes and comes with a new leak-resistant seal ring – that prevents any spills (even soup!)
The 1.5 L tray is made from food-grade stainless steel which is always healthier than plastic, and the cord is extra long (1.5 L). You even get a stainless steel fork and knife inside!

Buyers say that this is a safe and reliable portable oven that is easy to carry, use, store, and clean, and only requires about 25 minutes of heating – depending on the food and surrounding temperature.
However, if the food is just taken out of the refrigerator, heating may take a bit longer. The only downside is you can only use a metal container inside it and no frozen meals in cardboard boxes, or plastic microwave meals.

3. Rottogoon Personal Portable Oven – Hottest Portable Oven
- Size – 9.4” *7.2” *3.9”
- Weight – 1.4 pounds

It’s extremely lightweight and compact, (only 1.4 pounds) and easy to carry around.
This powerful mini oven slowly heats your food to 239 F (in only 30-40 minutes!), then auto reduces the temperature to 149 F and keeps it at this temperature – until you want to eat. It can even cook raw food such as chicken. If you leave it inside for more than 2 hours – it acts as a slow cooker!
It can be used with almost any heat-resistant flat-bottomed containers, including glass, plastic, Tupperware, metal, and foil – up to 9″W x 6.75″L x 3.5″H.

It’s a dual-use food warmer that can also be used in a car/truck.
In about 30-40 minutes it will heat your homemade meal to 158 F, while the handle stays cool (in wintertime heating may take 40-60 minutes).
The food stays hot until you are ready to eat it, but most consumers recommend not to leave it in for more than 2 hours to avoid overcooking.
The container is easy to clean and fill, and when you order from Amazon, you’ll also receive a fork and spoon inside the package.
While this is a great portable food warmer, keep in mind that you have to keep it bottom down to avoid leaking when you carry it.
