Can I cook raw food in a heated lunch box, or just warm up leftovers?
Most models are intended for reheating pre-cooked or leftovers. Some high-powered or portable oven models might handle cooking, but generally, it’s best to use pre-cooked food for safety and best results.
Will a USB heated lunch box work with my power bank or laptop?
Yes, for USB-powered models—just check that your power bank or port provides sufficient output (usually 2A or higher for optimal heating). Battery-powered models do not require external power once charged.
How do I clean my heated lunch box?
Most have a removable stainless steel inner container that is dishwasher-safe. The heating base should never be submerged; wipe it with a damp cloth after use and dry thoroughly.
