Review on 🔌 Cllena Dual USB Socket Charger 2.1A&2.1A + LED Voltmeter + 12V Power Outlet + ON-Off Toggle Switch Panel for Car Boat Marine RV Truck Camper Vehicles GPS Mobiles (Blue) by Jeremiah Whiteley

Do you need a set of instructions or a circuit As I've found out, there should be at least one instruction with a switch. I couldn't find any + or - indicators on the switch anywhere. It's a little frustrating. Light is a light tab, I'm considering turning off the blue light switch and replacing it with an unlit switch. This is used in the camper to check the battery status when driving in the tramp and also when charging phones (etc.). Put it in a spare battery at home and left it on overnight. He's a bright person. Supported GF and said if I can move it or turn it off. Well the product works well, need wiring instruction. Overall I am happy with the purchase for the price.
