POWOXI Upgraded 7.5W-Solar-Battery-Trickle-Charger-Maintainer-12V Portable Waterproof Solar Panel Trickle Charging Kit for Car, Automotive, Motorcycle, Boat, Marine, RV,Trailer, Snowmobile, etc.

Works as promised.
2011 Chevy Silverado. I don’t drive this truck but once or twice a week. When it’s cold out, the battery will usually not have enough amps to start my truck (below 32 degrees). I have it plugged into my 12 volt plug in (aka, cigarette lighter for us old folks). Keeps the battery topped off. Haven’t used the truck for about 6 days with temps in the low teens. Truck fired off without any issues. The light turns green with enough sunlight. Many of the days recently were cloudy and it still kept a trickle going into the battery. Works as expected.

Super easy and successfully tested battery to ensure its charging
Very easy to set up. I tie wrapped it to my stowed swimming ladder for winter trickle charging my battery. 2 weeks later, my battery is at 12.7v and tested this unit and found it to be generating 24w even though it states 7.5w.

Works exactly as expected on my boat.
Parked my boat for the winter almost 2 months ago. But I hesitated on adding a port for the charger.My boat sat for weeks and the battery dropped to 12.1v… probably from my bilge running during the rain.I put this solar charger on it and it brought me back up to 12.4v in 2 days (I tested after I unplugged the charger in the evening).So, I can say this not only maintains, but will improve battery voltage. Even with trees blocking sunlight most of the day and winters southern sun.It comes with multiple plugs. A solid plastic rubber casing with any number of ways to hook or hang it onto a boat or car.I might but a 2nd for my tractor but we’ll see.

So convenient that I ordered one for each car
I ordered this to keep some current going to our car batteries while we’re traveling. I was lucky that two of our vehicles worked with the panel by using the cigarette lighter/12v port. The last will need to have the cable ran under the hood to the battery, but no big deal. Batteries are getting too expensive to have them sit for a couple of months without being charged up, and I didn’t want to leave extension chords running all over the ground during winter. Very happy with the product. I’ll come back and update if there is a problem with anything mechanical in the panel over the next year.

I use this to keep the battery on my ride-on mower topped up. The shed has no electric so this is the ideal solution. Very pleased!!

まだ取り付けていないが、中身は良いものだと思います。バイクを放置することが多いため、エンジンがかかるように購入した。現在ツーリングを行ったため、充電できていると思いまだ取り付けていません。寒くなるので、そろそろ取り付けようと思っています。
