The lunch box for a warm bowl of soup at noon

The number that decides this one is 195°F within 2 hours. That is the stated time this 28 ounce electric lunch box needs to reach its top temperature, so it suits a lunch plugged in well before you eat, not one you want hot in ten minutes. The listing leaves out wattage, weight and dimensions.

The listing gives the capacity as 28 ounces and says that is more than 3.5 cups, enough for a portion of soup, stew or pasta. The heating claim is worded as a ceiling: it heats to 195°F within 2 hours. That describes a slow warm up toward a maximum, and the listing gives no temperature for shorter times, so a plan that depends on food being hot at a set minute has nothing to rest on.

The inner container is removable stainless steel. The lid seals tightly and has a steam release valve, which the listing credits with reducing spills in transit. The title says spill free, but the feature text says only less spill, and the second wording is the more modest one. The title also says dishwasher safe without naming the parts. The electric base is a part the listing does not address, so check the manufacturer instructions before washing it.

Power sets where it works. It supports only a standard 110V outlet, and a 12V power cord is not included, even though the title mentions car use. Insulation is stated at up to 2 hours hot or up to 3 hours cold. Weight, dimensions and cord length are not given.
