Review on Battery Tender 5 Watt Solar Battery Charger 12V - Weatherproof Mountable Charger with Multiple Mounting Options and Accessories - 021-1172 by Troy Robinson

I am the happy owner of a Battery Tender Plus which I use on a show car in my garage. So when I was looking for a solar maintenance device, it was an obvious choice for me to try this Deltran product. I bought this for my former commuter car which has become a 'monthly car' due to COVID-19 when my company moved from home to work. As I don't drive much due to blockages, I noticed that the engine is starting to slow down as temperatures drop earlier this winter. This product seems to take over the task of charging the battery when the car starts directly after being plugged in for about a day. I use it with the supplied OBD2 adapter as the 12V socket/cigarette lighter does not stay on when the car keys are removed from the ignition. My only concern is the suction cups that need to be attached to the inside of the windshield - they don't seem to last long in cold weather. As a result, I just leave the bar on my dashboard and everything seems to be working just fine.
