This is an AODEA (オーディア) relay-equipped power cable, 30A MAX, model 4968, made by Aimon (エーモン). I purchased this in 2017 and have kept it stored in my garage without using it. The packaging has some folds, creases, and dirt, but the main unit has never been taken out. I hope it can be useful to someone.
