600ML USB Electric Heating Lunch Box Portable Picnic Milk Drink Food Heater Stainless Steel Food Warmer Container 5V 12V 24V

Note:

1. The electric constant temperature insulation tank uses food grade 304 stainless steel liner, which is safe and reliable.

2. The electric constant temperature insulation tank uses USB data cable to provide energy, heating anytime and anywhere, long-term insulation.

3. The correct way to use the electric constant temperature insulation tank: put hot food into the insulation bucket and connect the USB cable, which can provide long-term insulation and maintain an inlet temperature of 60 degrees at any time.

4. The USB power of the electric constant temperature insulation tank is very low and does not have the function of quickly heating food. (Note that this is a long-lasting insulation tank powered by USB, not a quick heating tank)
