It is a prototype of the bag that inserts the fan of the USB type and uses it.
The dry battery and the solar film can be switched.
It can become cool while it waits at the station on a hot day.
It is effective when using it to dry the sweat that comes out when arriving at the office.
市販のUSBタイプの扇風機をそのまま差し込んで使うバッグを作ってみた。
乾電池とソーラーフィルムの切り替え式で、
暑い日に駅のベンチで電車を待つ間に使います。さらに
職場に着いたときにドット出る汗を乾かすために使うと効果的です。
