What Makes Our Electric Lunch Boxes Stand Out in the Global Market?

In the competitive portable appliance sector, reliability and user safety dictate brand reputation. Unlike trading companies, we are a true source factory with over a decade of deep technical accumulation in small thermal appliances.

One of our core competitive advantages lies in our Dual-Voltage Adaptability. We engineer electric lunch boxes equipped with dual power cords (110V-240V for indoor use and 12V/24V for cars/trucks), catering specifically to the booming outdoor, camping, and commercial logistics markets.

Furthermore, we eliminate compliance risks for importers. Our facility maintains a flawless track record of passing stringent international testing, holding active reports and certifications for ETL, UL, CE, CB, FCC, and LVD. Combined with our use of premium 304 stainless steel and BPA-free plastics, partnering with us ensures your products move swiftly through customs and confidently onto retail shelves.

Semoga FAQ penggoreng udara ini dapat membantu Anda

?

Do your electric lunch boxes support both Car and Home use?

Yes, many of our best-selling models feature a dual-interface design. They come with two separate power cords: one for 12V/24V (suitable for cars and heavy-duty trucks) and one for standard 110V/220V/240V wall outlets, making them highly versatile for commuters and drivers.

?

Are the materials used safe for food contact?

Absolutely. We strictly utilize food-grade PP plastic for the outer housing and accessories, and premium 304 stainless steel for the heating liners. Our products carry FDA and LFGB test reports, ensuring 100% safety when exposed to high temperatures.

?

What is the difference between a "Heated Lunch Box" and a "Cooking Lunch Box"?

Our standard Heated Lunch Boxes (typically 40W-80W) use PTC technology for slow, even thermal insulation and reheating of pre-cooked meals. Our Cooking Lunch Boxes (typically 200W) feature advanced heating plates and water-boiling mechanisms, capable of cooking raw rice, steaming vegetables, and boiling eggs from scratch.

?

Can the stainless steel inner trays be washed in a dishwasher?

Yes, the removable 304 stainless steel inner trays and the plastic compartments are completely dishwasher safe. However, the main electrical base/housing must never be submerged in water.

?

What certifications do your factory and products hold?

Our manufacturing facility is ISO9001 and BSCI certified. The products themselves hold comprehensive international certifications, including CE, CB, RoHS, EMC, LVD, FCC, ETL, and UL, ensuring barrier-free entry into major global markets.

?

Are the lids completely leak-proof?

Our premium models are equipped with thickened silicone sealing rings and reinforced snap-down latches on all four sides. This heavily prevents soups and liquids from spilling during bumpy commutes.

?

What is your daily production capacity?

Our factory covers 8,000 square meters and is equipped with over 30 advanced production machines. We possess a daily production capacity of up to 8,000 sets, allowing us to comfortably handle large volume wholesale and urgent peak-season orders.

?

Can we customize the internal compartments of the lunch box?

Yes. Depending on the model, we can provide single-compartment stainless steel liners for maximum capacity, or segmented liners (such as 2-grid or 3-grid layouts) to keep different foods from mixing. We also offer additional plastic sub-containers.

?

What is the standard packaging, and can it be customized?

The standard packaging includes the lunch box, power cords, an instruction manual, and a standard color box. We fully support OEM packaging—you can provide your own artwork for the color box, and we can even include customized thermal insulation carry bags (like in our portable oven series).

?

What is the heating time for a standard 40W electric lunch box?

Heating time depends on the food volume and initial temperature. Generally, at room temperature, it takes about 20-30 minutes to thoroughly heat a meal using the 40W PTC heating system. Frozen foods will require more time.

?

Do you offer SKD/CKD shipping for local assembly?

As a flexible source factory, we can accommodate SKD (Semi-Knocked Down) or CKD (Completely Knocked Down) shipments if your country offers tax advantages for local assembly. Our engineers can provide the necessary technical documentation.

?

How do you conduct quality control before shipment?

Quality is our priority. Every unit undergoes rigorous testing on the assembly line, including high-voltage safety tests, grounding checks, and functional heating tests. We strive for excellence to ensure an ultra-low defect rate for our B2B partners.
