My wife's car battery would go dead if it did not get driven because of all the background electronics drawing from the battery while it sits parked for a week or more. This works great for keeping the battery charged while parked.

Very easy setup. Multi mode charging selector allows parring the device to the type of battery you are trying to charge. Due to the relatively inefficient nature of solar panels in general, this size does appear to “trickle charge” or maintain my truck battery.

Nothing to dislike, but I like the fact that it trickle charges batteries throughout the winter when you’re not using that vehicle. If batteries discharge through the winter and freeze, it ruins them and that could be a $200 bill.

GMC Duramax SLT. These newer vehicles with all the electronics running in the background. You can’t leave parked for any length of time without draining your batteries. My trucks are not parked near power. These 20 watt panels are putting out 1amp in direct sunlight. Figure I’m getting 4-7 amps in coarse of a winter day. Depending on overcast etc. from what I have read the average vehicle drain is about 3.4 amps per 24 hour period. So far I am finding that this panel is keeping up. It has an excellent MPPT controller that is easy to set for the type of battery. And discontinuous charging once battery has reached full. This truck will have sat about a month upon my return. I do not foresee any problems. But will throw a meter on the electrical prior to starting. If I find it is not keeping the batteries topped off will update.1/5/2025 well I came back to my batteries voltage being down to 11.7 volts. Figured out not the panels fault. Had set up on inside windshield held up by visor to catch angle of the sun. I didn’t take into consideration was the UV protection from the glass that inhibits the panel from doing its job. (Same reason your self tinting glasses won’t turn dark inside the vehicle even if you set them on the dash). Once I set the panel in front of the windshield made all the difference.

I’ve been looking for a charger that I can use outside and year round in upstate New York. Thus Suner Piwer 20 watt is the perfect device. It was super easy to set up. It is truly plug ‘n’ play.It works great keeping The 12vAGM battery in my Kubota RTV 900 farm vehicle fully charged when I need it. As I don’t use the Kubota that often, it’s great that now I just start it right up and go. Before I had this charger I’d have to jump it half the time. That’s a thing of the past. You won’t regret buying this solar charger.
