Review on Versatile Nilight 4-in-1 Charger Socket Panel with Dual USB Power Outlet, LED Voltmeter, Cigarette Lighter, and Rocker Toggle Switch - Perfect for Trucks, Cars, Marine Boats, RVs - 2 Years Warranty by Darian Massey

Nice to have! I bought this little four position switch for my truck because I use it all the time and my battery always runs out so I can start. I really like the Meyer voltage. Now I can see when I'm running low and need to run it to charge. The switch is great for my LED lights I have around the bed and the 2.1 amp USB port is great for fast cell phone charging. It is easy to install and the thickness is large. It's a good, solid piece for my Arsinol. Should have gotten this a long time ago. Update, very cheap product. It shorted out and caught fire. Worst product ever. Do not buy. The company doesn't stand behind this product and neither should you!
