FYI: We've been reviewing and rating products for the home and families since 1994. We don't take money or freebies from the brands we review. Our work is 100% reader-supported!

Best Heated Lunch Box For Cooking: HotLogic Mini Portable Oven – Food Warmer and Heater – Lunch Box

Let’s talk heated lunch boxes.

Popular with folks who work “in the field” (think construction, truckers or other folks on the go), heated lunch boxes pretty much do what they promise—they heat up food. 

That said, we should note one important caveat after trying out several of these ourselves: heated lunch boxes are NOT speed cookers. You will need to experiment with cooking times to find the right solution. 

Yes, you can reheat food in a heated lunch box—and most will keep food hot for hours without drying it out. But don’t expect to plug in your heated lunch box and have it cook a full meal in 15 minutes.

In our research, we found some heated lunch boxes are better for cooking than others. This model by HotLogic impressed us with its quality and durability. Here’s more:

What We Liked

• Leftovers take about half an hour to warm up.

• Nicely sized for most users.

• Don’t have to use a dirty microwave at work!

• Can use your own container as long as bottom is flat.

• Uses standard electrical outlet.

• Affordable.

What Needs Work

• Not ideal for use in a vehicle (there is no 12 volt plug).

• No auto shut-off.

• Too small in size for some folks.

How We Pick Products To Recommend

We often turn to our readers (3 million strong!) to find products to recommend. We ask our parent readers for their favorites and consider their real-world experiences in our recommendations.

When we test a product, we always purchase it with our own monies. We do not take free samples, as we believe that compromises our independence.

We also fact check manufacturer information with our own measurements. If a maker claims a product weighs X pounds, we will weigh it to make sure. If the battery life is supposed to be six hours, we will see how it stands up in the real world.

In some cases, we will do interviews with experts in the field to get additional feedback on products.

To get hands-on time with products, we regularly meet one-on-one with gear companies and even tour manufacturing facilities. (When we do this, we pay our own travel expenses).

Why Trust Us

We’ve been rating and reviewing products for the home and families since 1994. We do extensive research, evaluating products with an eye toward quality, ease of use and affordability.

We make our living from affiliate commissions, but we always recommend what we think are the best bets for our readers (not the ones that are the most expensive). We are always looking for products that offer the best bang for the buck.

Our independence is a key reason why we have been doing this so long. As we mentioned above, when we purchase a product for hands-on testing, we do so with our own money.

Here’s another key point: we don’t take money from the brands we review. No free samples, no sponsors, no “partnerships.” Our work is 100% reader-supported!
