Product Description

Designed in Holland, the Mimi Moto is a forced-air gasifier cookstove designed to operate using locally produced biomass pellets as fuel. Two removable burning chambers are used; the larger for high powered flame and a smaller biomass chamber for low power simmering. The built-in fan is powered by an external rechargeable battery pack. A solar panel is included to charge the battery pack for off-grid applications. Promotional and instructional videos about the stove available.

Mimi Moto is based in the Netherlands.
