Review on 🔌 Green Quick Charge 3.0 Dual USB Charger Socket - Waterproof 12V/24V USB Outlet with Touch Switch DIY Kit for Car, Golf Cart, Marine, Boat, RV, Motorcycle, Truck, and More by Chad Overturf

Make a portable power supply for outdoor use and it works great. When off, it consumes some current, about 4mA. This low power consumption is due to the capacitive touch power button. When on, it draws 14mA with no load. The outlet is on by default when the device is first turned on, but a quick press turns it off. Sensor circuit so that it also turns on when a load is applied.
