The special thing, however, is that the built-in solar cells on the lid of the lunchbox can juice up the 10Ah power bank from sunlight. It has also got a built-in USB-C port for you to fully recharge the included power bank from a faster power source.
As you see, the SunnySide lunchbox can both heat and cool your favorite meals.
That said, you can preserve your food items fresh by keeping them cool in the lunchbox for up to 20 hours, thanks to its built-in cooling system, which works on some fans and coolant.
When it is the time to eat and you want to consume it hot, you can simply heat up the dish in a few minutes, thanks to its built-in induction coil technology.
