The Noonwell Duo is a rechargeable electric lunch box for people who need a hot meal where there is no outlet. Its removable 90 Wh battery heats 650 g of chilled food from 4°C to 74°C in about 45 minutes at a room temperature of 22°C. Two sealed stainless steel trays hold 1.1 L in total.

For shifts without a kitchen

Use it in a service vehicle, site cabin, or shared break area when a microwave is not available. Set the start time before work. The box begins heating automatically so the meal is ready at the planned break.

Two separate steel trays

The 700 mL main tray holds an entrée. The 400 mL tray keeps a side separate. Both are made from 316 stainless steel and use removable food-contact silicone seals.

Controlled reheating

Choose a 63°C hold setting or a 74°C reheat setting. A probe beneath the main tray checks temperature during the cycle. The heater shuts off after reaching the selected setting.

Rechargeable or plugged in

The removable 90 Wh lithium-ion battery supports one full reheat cycle with up to 650 g of food. The lunch box can also run from a 100 W USB-C PD adapter. Battery charging pauses while the heater is active.

Questions and answers

How long does the Noonwell Duo take to heat refrigerated food?
With 650 g of food starting at 4°C, it reaches 74°C in about 45 minutes at a room temperature of 22°C. Dense portions or a full 1.1 L load may need up to 60 minutes.
Can the lunch box heat food without being plugged in?
Yes. The removable 90 Wh battery supplies one full 74°C reheat cycle for up to 650 g of food.
Can I use both trays at the same time?
Yes. The 700 mL and 400 mL trays heat together at the same selected setting. Their silicone seals keep the foods separate during upright transport.
Is the Noonwell Duo suitable for soup?
The trays resist spills when latched and carried upright. They are not made for inverted transport, so leave at least 15 mm of space below the rim when packing liquids.
Which parts can go in a dishwasher?
The stainless steel trays, silicone seals, and inner lid are dishwasher safe on the top rack. Wipe the heater base with a damp cloth and never immerse it.
Can I schedule the lunch box to start heating later?
Yes. The timer can delay heating by 30 minutes to 10 hours in 30-minute steps. The display shows the planned start time and selected temperature.
Can the removable battery be taken on a plane?
The battery is rated at 90 Wh, below the common 100 Wh carry-on limit for lithium-ion batteries. Keep it in carry-on baggage with its contacts covered, and confirm the current rules with the airline.

★★★★★
I set the timer at the start of my shift, and lunch is hot by noon. The smaller tray keeps rice separate from the main dish.
Maya
★★★★
The battery lasted through a full heating cycle in my work van. It is heavier than a normal lunch box, but the stated size and mass are accurate.
Daniel
★★★★★
The steel trays come out without fuss and fit on my dishwasher's top rack. The lid stayed dry around the seals during an upright commute.
