Rechargeable 40W Electric Lunch Box with 304 Stainless Steel Liner and Timing Function

This rechargeable electric lunch box is designed for people who want a hot meal without relying on a shared microwave. It uses USB power at 40W with a 5V rated voltage and 50Hz rated frequency, and it includes a timing function so you can set when heating begins. The vacuum insulation and double insulation help retain temperature, while the 304 stainless steel liner gives you a food-contact surface that is straightforward to wipe clean. The plastic body keeps the unit to a stated 245 x 90 x 124mm, and it is available in ivory white, violet, or grass green. Each order contains one electric lunch box in English packaging. This description sticks to the specifications provided, so you can compare the stated power, materials, and size with your own needs.

Features and Construction

The construction centres on a 304 stainless steel liner inside a plastic body, with vacuum insulation and double insulation around the food compartment. Power comes through USB at 40W and 5V, and a timing function controls when heating starts. These are the confirmed build details from the source information.

Material and Build

The liner is made from 304 stainless steel, a material often chosen for food containers because it does not absorb odours or stains in the way some plastics can. The outer body is plastic, which forms the shell around the insulation and electrical parts. Vacuum insulation and double insulation are both stated functions, working together to slow heat loss between the food and the outside air. The 40W rated power and 5V rated voltage describe the electrical input, and the 50Hz rated frequency is also listed.

Size and Practical Fit

The product measures 245 x 90 x 124mm. That rectangular footprint is intended as a large capacity format for a full meal, and the dimensions give you a clear idea of the space it will take up on a desk or in a bag. Because the body is plastic and the liner is stainless steel, the overall weight is not stated in the source data, so no weight figure is given here. The size and shape are the only measurements confirmed.

Uses and Placement

This lunch box suits a home office desk, a workplace without a microwave, or any setting where USB power is available. The timing function helps you plan when food starts heating, and the insulation functions aim to keep it at temperature afterwards.

Event or Professional Use

For longer shifts or meetings, the timing function lets you set the lunch box to begin heating at a chosen point rather than watching it. The vacuum insulation and double insulation are intended to hold temperature once heating stops. The 304 stainless steel liner can be wiped clean between uses, which is useful when you need to pack the unit away after eating. The 245 x 90 x 124mm size gives you a fixed reference for whether it fits your bag or locker.

Everyday Home Use

At a home office desk, the USB power type means you can run it from a compatible adapter or power bank rather than a mains socket. The 40W power and 5V voltage are the stated electrical requirements, so check that your USB source can supply them. The three colour options ivory white, violet, and grass green let you choose a finish that matches your setup, and the single-box package keeps the contents simple.

Benefits and Buying Value

The main practical benefits come from the combination of a stainless steel liner, insulation, and a timing function. These features are aimed at making a warm meal easier to manage during a working day.

Reuse and Low Maintenance

The 304 stainless steel liner can be wiped clean after each use, and because it is a separate material from the plastic body, you can clean the food-contact area without submerging the electrical parts. The timing function reduces the need to monitor heating manually, and the double insulation is designed to retain heat so you are not reheating repeatedly. These are the low-maintenance aspects supported by the source text.

Why Choose This Product

Choose this lunch box if you need USB-powered heating at a stated 40W, a 304 stainless steel liner, and a timing function in one unit. The 245 x 90 x 124mm size and the choice of ivory white, violet, or grass green are the concrete differentiators. No price, pack count beyond one unit, or performance rating beyond the listed specifications is claimed, so you can judge it on the facts provided.
