Hot Food at Your Desk. Hot Food in Your Car. No Microwave Needed.

This 600ml USB electric lunch box keeps your food at a constant 60°C — perfect for the office, car, truck cab, or anywhere you have USB power. 304 food-grade stainless steel liner is safe, durable, and easy to clean. Simply load with hot food, plug in via USB, and the 10W heating element maintains temperature for hours. Compatible with 5V (power bank/laptop), 12V (car), and 24V (truck) power sources.

⚠️ This is a constant-temperature insulation box, not a rapid heater. It maintains temperature — it does not quickly reheat cold food. For best results, fill with pre-heated food before plugging in.
