Review on 🔌 ELECTOP 12V USB Outlet Socket Panel: Waterproof Dual USB Car Charger, LED Voltmeter, ON-Off Rocker Toggle Switch - Ideal for Car, Boat, Marine, Motorcycle, RV - DIY Kit by Kevin Caldwell

a long time ago to have access to the power supply in the rear of my van. I used the switch to be able to turn on the bedside lamps while keeping the charging ports on even when the lights are off. (I did some extra wiring to make this possible) Good quality product itself, my voltmeter works on arrival. I know some people have had trouble with that. In order to improve the product, I would advise them to make a waterproof seal. (I used silicone but would be nice with a gasket) I will update my review if the product still fails. Overall great panel, charges my phone and tools perfectly!
