How Do You Choose a Portable Food Warmer?
Here are the most important features to check before you buy a lunch box cooker:
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 (Lunch Box Cookers)
And now, here are the top 6 heated lunch boxes, with their pros and cons:
1. YOHOOLYO Electric Lunch Box (110V/12V) Best for Dorms
- Size – 9.45 x 6.69 x 4 inches
- Weight – 2.2 pounds
- Container – only use with stainless steel container (included)
The YOHOOLYO 110V electric lunch box food heater comes with a convenient and toxin-free stainless steel container – divided into 3 compartments to separate your food the way you do at home.
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 we 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 a great portable food warmer, keep in mind that you have to keep it bottom down to avoid leaking when you carry it.

This safe and reliable portable oven is easy to carry, use, store and clean, and only requires about 25-40 minutes of heating – depending on the food and surrounding temperature.
