Review on 🔌 RecPro RV USB Charging Port: Dual Charger Socket, Black Recessed Mount for RV, Camper, Trailer by Brent Henderson

Unit does NOT come with screws but is great for RV's due to its shallow depth and pre-wired unit. As mentioned in the answer to the question, make sure you have it plugged in correctly. My old device had black and red wires. This block has black and white wires. So I thought of connecting black to black and red to white but it didn't work. After flashing it worked. The black wire from the block now connects to the red wire on my trailer and the white wire to the black. I also added a mini fuse holder (15A) between the unit and the trailer wiring. I used to use a multimeter to check the voltage applied to the failed device. So if it didn't work, I knew either the wiring was mixed up or the device was defective. Luckily it was the wiring. If you look closely you can see a lit little LED. It burns constantly but not intrusively. So far, so good. I will update the review if anything happens on our upcoming trip. .
