A common struggle of working in an office is packing a warm meal for your lunch, only to eat it cold because you don’t have access to a kitchen (or your only option for reheating is a microwave that leaves food chewy and unevenly-heated). While vacuum-insulated food containers can typically maintain temperatures for a few hours, there’s often a time limit on how long they’ll hold in heat. But luckily, there’s another simple solution out there to keep your food or beverages piping hot throughout the day: a portable food warmer.

One option that Amazon shoppers have been loving is Crock Pot’s Lunch Crock. The brand behind the famous slow cooker, Crock Pot’s portable 20-ounce food warmer is compact enough to use for traveling or in-office lunches, and customers swear that it’s perfect for “anyone who wants a hot lunch.” The best part? It’s only $25.

In this mini food heater, Crock Pot has essentially created a cooking tool that contains elements of its popular slow cookers. While the Lunch Crock isn’t designed to cook raw meals (I mean, you technically could, though it’d take ages), it is made for reheating cold meals that were already fully cooked before being refrigerated or frozen. It comes with a warming base that—as long as it’s plugged in—slowly and evenly heats up meals so that by the time you want them, they’ll be piping hot and ready to eat.

The Lunch Crock is made up of two parts. The first is a heat-proof exterior that includes a lockable lid, a cord storage area on the base, and a convenient carrying handle for easy transport to and from the office sans spills. The second is a removable food container inside that holds up to 20 ounces of food and comes with its own leak-proof lid. Washing this ingenious little device is also super simple: The inner food container and its lid are dishwasher-safe or can just be rinsed with warm, soapy water.

Shoppers who use the food warmer rave that it makes hot meals possible no matter where they are. “This is a very useful way to reheat leftover soups, stews, and casseroles without using a microwave,” said one customer. “Like other reviewers have mentioned, there is often a line to use the microwave at lunchtime and I'm not really a fan of microwaved food, so this is a good solution.”

Others praised how convenient it is for traveling. “After my first use I'm in love,” wrote a reviewer. “I travel full time and need small appliances for those times when I don't have a kitchen available.”

Available in four colors, the Lunch Crock has nearly 2,300 five-star reviews (as well as a stellar 4.7-star rating), and considering the many happy testimonies, this portable lunch heater might just be one of the best solutions for keeping food warm on-the-go.
