Gizmodo Japan has highlighted three items that improve the comfort of sleeping in a car. These include the Jackery SolarSaga 100 Prime portable solar panel for device charging, the SEIWA magnetic curtain for window privacy, and the Yamazen portable fridge-freezer. The solar panel mounts on a roof rack and charges a portable power station even while parked. The magnetic curtain installs without drilling and must be removed before driving. The fridge-freezer runs on household AC and a cigarette lighter socket, with a minimum temperature of -18 °C.
