Four Items for Summer Car Sleeping: Fan, Fridge, AC, and Power Station
Original source: ダイヤモンド・オンライン

In Brief

An author with eight years of car-sleeping experience recommends four items for beating the heat: BougeRV F02 fan, BougeRV CRH20 fridge, EcoFlow WAVE 3 AC, and DJI Power 1000 Mini. Also tested budget gear from Muji and Nitori.

Author's Picks

An author who has slept in cars for eight years listed four items most useful against summer heat: the BougeRV F02 rechargeable fan, the BougeRV CRH20 portable fridge, the EcoFlow WAVE 3 portable air conditioner, and the DJI Power 1000 Mini portable power station. The fan costs 23,980 yen, and the fridge with battery costs 43,499 yen.

Budget Gear Test

A Japanese outlet conducted a two-day test of heat-countermeasures for car sleeping using items from Muji and Nitori costing up to 5,000 yen. On the first night at 33°C, the cabin temperature dropped to 25°C by morning; on the second night at 40°C, it did not fall below 30°C. The test showed that pre-cooling the cabin with AC is key, and in extreme heat, sleeping in the car should be avoided due to heatstroke risk.
