Review on 4-in-1 Marine Switch Panel with 12V Dual USB Charger Socket, LED Voltmeter, Cigarette Lighter Socket, and LED Lighted ON/Off Rocker Toggle Switch for Truck Car Marine Boat RV by John Destruction

I installed this on the side of the plastic ammo box to provide a "power supply". In the ammo box I installed two SLA 12VDC 7Ah batteries that are fully charged by two* external solar panels. The 12V batteries are then ready to charge any 12V or 5V DC devices such as iPhones, iPads and even USB powered chargers for rechargeable AA and AAA batteries (which are then used in flashlights, radios etc ) to supply power. d.). I can also charge the "power bank" using a 12V cigarette lighter in the car or a 120V AC charger. our electrical service within a few days or weeks. plug it into my "power bank" for fast charging.
