Bought for gun safe. I made a custom install using one of the bolt down holes up front and a wood box from crate. Had to cut cord and use an approved Wago connector. Enough spacing for wall warts to power lights, dehumidifier and fanless computer. 65W total. It can only provide full 65watts if one USB-C ports is used.
