  • Brand: Buddew
  • Manufacturer: Buddew

The Buddew Electric Lunch Box is a versatile and budget-friendly option that excels in its 3-in-1 functionality, supporting 12V, 24V, and 110V power sources.

During testing, the Buddew performed reliably, heating food evenly without drying it out. Its 1.5L capacity is sufficient for a full meal, and the additional compartment is useful for separating different food types.
