Review on 🚗 Linkstyle 12V Cigarette Socket Panel with 3-Socket Cigarette Lighter Splitter, 12V 4.2A Dual USB Car Socket, LED Lighted ON Off Rocker Toggle Switch Panel, and LED Voltmeter - Ideal for Truck, Car, Marine Boat, RV by Marty Drury

I used a Hammond RL6555 project box to mount a panel next to a bed in a camper trailer. It can also be flush mounted in a cabinet as long as you have at least 3 inches of clear space behind its front. Three 12 volt outlets connect my ventilator and CPAP machine with an extra outlet for occasional use. USB keeps tablet and phone charged. These and other trims, as well as replacing all lighting fixtures with LEDs, bring our 20-year-old R Vision trailer into the 21st century. The voltmeter is nice to look at when my 400 watt solar panels on the roof generate electricity in the morning. The blue light from the meter and USB ports serves as a night light.
