Review on Nilight Charger Voltmeter Stickers Warranty by David Bartan

Finally found what I was looking for for my RV: a switch to turn on the lights and a heater for the drinking water tank. No stencil, made of thick paper. I had a question about using one of the switches as a power switch and the answer helped me. So to turn the unit on, I press the switch on the far right, and then I can use the other three switches for lighting/heating. Love having USB for phones and a battery indicator which my RV doesn't have.
