“Excellent quality, 12/24 volt, I bought 4, 1 for the truck, and 3 for the campervan, 1 on the dash, 2nd at the front of the camper, 3rd at the rear of camper, works very well.”
“Perfect for older vehicles that don't have a million USB ports everywhere in the back. Now that is no longer a problem. And if they back seat drivers/kids complain I can turn off their chargers from the front easy as a push of a button.”
