The Mechooler mechanical cooling container is a hand driven, portable can and flask cooling device. It does not use any electricity or batteries at all. Ready to go from the start - it can also contain free liquid and use the lid as a mug. It doesn't require any accessories.
It actively cools via a hand driven fan and heatsink, and in turn the inside spins at the same time. Then it passively cools via a cooling gel pad and isolation. Combined it creates a powerful cooling effect.
Lightweight, small and portable, bring it with you wherever and whenever you go.
