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.

Does not charge more than one device at a time…

Color: Black, Size: 10FT

Does not charge more than one device at a time. I have a USB C to charge my iPhone. If I connect any other USB type plug into the socket, my iPhone will disconnect from charging. I’ve also tried this with my Apple Watch and it disconnects from charging as well. I know it does not charge more than one device at 65W, but it should be able to charge more than one device at a time. It has two USB ports and two USB C ports. Maybe this one is defective?
