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 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 a great portable food warmer, keep in mind that you have to keep it bottom down to avoid leaking when you carry it.

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