HiKOKI Cooler Box, Compact, AC/DC Compatible, Free Shipping

This is a portable cooler from HiKOKI, formerly Hitachi.
It can be used without a power source by attaching a battery.
I purchased this item on Mercari stating it had been used only a few times, but I have kept it without ever using it myself.

I intended to put it in my father's work van, but it was too large, so I never had the opportunity to use it.

I tested its operation by plugging it into an outlet.
I placed one room-temperature plastic bottle inside for an hour, and it became cool to the touch.

It comes with an AC cable and a car cigarette lighter socket cable. Batteries are not included.

It can also be used as a charger, and I was able to charge two batteries.

There is no instruction manual, so please download it from the website.
