A Japanese crowdfunding site, Makuake, has pre-sold the Easy Stove, which makes it possible to use a cooking cassette stove or small gas stove as a stove for warmth, and it has gained popularity with sales of 6.2 million yen. I don’t think it has enough heat to warm up a large tent used for family camping, but it looks good for use in a solo or duo tent. By the way, the same product is being sold in China at a lower price, and the company is accepting cancellations from buyers. You need to be careful when you ask a Chinese manufacturer to produce it for you.
