    5.0 out of 5 stars Great portable heater for hot breakfast/lunch/dinner at work I purchased this for my husband as he is never in the same place each day and gets tired of the cold options for breakfast and lunch. After charging, this heater works great to heat up anything from oatmeal to soup to spaghetti to meatloaf and veggies. Highly recommend if you are tired of cereal for breakfast on the run or salads and sandwiches for lunch at work.Variation: Size: 4 Cups
