Review on LiDiVi [Upgraded Version] Dual USB Car Charger with Quick Charge 3.0, Waterproof 36W 12V USB Outlet - Fast Charging, Voltmeter & Switch for Car, Boat, Marine, ATV, Truck, and More by Michael Briggs

This small socket is impressive. First, I liked that the kit included plastic grommets for attached wires to seal them. Little details like this tell me a quality product. The loading speed is faster than I expected. I love that this outlet has an on/off switch. I installed it in our RV for the charging port next to the bed and it fits perfectly. When the charger indicated battery voltage I had to test it with my voltmeter to see how well it was working. He went to his batteries and of course he was on top. I have already recommended this product to a friend for the same purpose in his RV.
