Cordless heated lunch box 1.3L

The DNBeffulgent HM899 is a battery-powered food warmer with a 1.3 litre capacity and a 20000mAh lithium-ion pack. It heats meals to 220 degrees Fahrenheit without a mains connection. Office workers, drivers and outdoor crews can eat hot food away from power outlets.

Battery limits and scheduled heating

The 74 watt-hour pack delivers up to three hours of continuous heating followed by one hour of keep-warm mode. Scheduled heating starts automatically two hours before the set mealtime when the unit is powered on. The function requires at least 90 percent charge and the clock to be set correctly.

Capacity and practical headroom

The 1.3 litre container holds 5.5 cups, a 45 percent increase over 0.9 litre alternatives, and fits a full adult meal with the included divider tray. Leak-proof silicone sealing keeps liquids contained during transport. The insulated carry bag helps retain heat in cold conditions. Buyers needing multiple meals or multi-day operation without recharging should consider a larger power source.

Questions about this item

How does the 1.3 L capacity compare with typical lunch boxes?

The 1.3 L volume equals 5.5 cups, which is a 45 % increase over the common 0.9 L size, letting you carry a full meal rather than just a snack.

What does the 220 °F rating mean for daily use?

The heater can reach 220 °F, so food gets steaming hot during the two-hour heat phase and then stays warm for an additional hour in keep-warm mode.

How long does the 20 000 mAh battery last between charges?

The 74 Wh lithium-ion pack delivers three hours of continuous heating — two hours active heating plus one hour keep-warm — before needing an overnight recharge.
