Review on 🔌 USB C & USB A Dual Port Car Charger Socket: Waterproof, LED Voltmeter, ON/Off Switch, 12V Outlet with Cap - Ideal for Car, Boat, Golf Cart, Bus, RV, Automotive Marine ATV Truck by Dre Fowler

I replaced the USB 3.0 charging socket in my kayak with this device and I am 100% satisfied. This unit is supplied with a cord, built in fuse and a suitable hole saw to install the unit. It has a button that is used to display your battery voltage and a removable rubber cap/cover that makes the connectors more waterproof. I left the attached rubber plug/cover as it is in the kayak but would probably remove it if it was in the vehicle. FYI it was panel mounted so note the rocker switches and panel in the photos I have included are not part of the kit being sold here. Only one charging port in the middle of the switch panel.
