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 Kendrick Dooley

Not the best picture. but easy enough to install if you have wiring experience and can understand the circuit. Be sure to install a fuse or circuit breaker in series with the circuit breaker power supply. I used a 12V/10A marine switch as a starting point. If it turns up too light I'll take it, but it seems enough to charge a 12V TV, 12V fan and iPad at the same time. There are two 2.1a USB ports so you can quickly charge phones or tablets at the same time. The ports can be moved to any desired position on the front, which is also a nice feature. Individual ports can also be purchased as spares or if you need more USB ports.
