Background of Collaboration

Daiwa Wireless Electric Co., Ltd., a company founded in the 1940s dealing in electronic parts and home appliances, developed this product following the 2024 Noto Peninsula Earthquake to solve the problem of 'no access to hot water' in disaster-affected areas. The collaboration between Campingcar Co., Ltd., which promotes the use of motorhomes as 'mobile shelters,' and Daiwa Wireless Electric's commitment to disaster relief has led to this partnership.
