POWOXI 20W Solar Panel 12 Volt Solar Battery Trickle Charger Maintainer Waterproof Solar Panels Kit 12V Batterys, 20Watt Solar Panels for RV Boat Car Motorcycle Snowmobile, with Upgrade Controller

There's not much to say about this. I put it in the sun. Connected to a battery with a 12.2 volt charge. Came back a few hours later and it was much higher. Easy to use.This is what I am going to use to keep my boat batteries charged. No need to keep them plugged into the house.

The media could not be loaded. Because it is a dependable and effective source of solar power, the 10W Solar Battery Trickle Charger has proved to be the ideal traveling companion for me during the course of my adventures. The solar panels had a solid build due to the use of high-quality materials in their construction, and they were able to survive a wide range of climatic conditions. Due to the fact that I am a frequent traveler and thus often find myself in environments with varying weather conditions, the fact that this solar charger is waterproof was a major selling factor for me. On the road, I am no longer nervous about getting wet from unexpected rain showers or splashes. Because of the detailed instructions that were supplied, putting up the solar panels was an absolute snap. The upgrade package provided me with everything I needed, including all of the required wires and a controller for the update. My batteries were kept in excellent condition as a direct result of the controller's effective regulation of the charging process, which prevented them from being overcharged and kept them in optimal condition overall. The 10W solar panels never failed to keep my 12V batteries fully charged and maintained a steady charge during all of my road excursions. I was pleasantly delighted to see that the solar panels were still able to provide a respectable quantity of electricity even on days when the sky was overcast. I was able to extend the life of the batteries in my RV, along with those in my other vehicles, including my boat and motorcycle, by using this continual trickle charging method.

I like the convenience of having it for my Corvette that I drive on special occasions so it doesn’t see much rode time,but I like the idea of knowing that will start when I need it to! , thank you for your service!

What I really like are the hard plastic feet for putting this on the dash, precluding melting suction cups. This is a nice small size for 20W and their separate voltmeter will measure panel output disconnected from the battery.

It does the job to keep the battery maintained without draining down. If you have a vehicle that you can run extension cord to it to plug the battery maintainer this device does the work. Has been months since I installed and the battery never went low on voltage.

Safe and inexpensive way to keep my truck battery safely chargedat peak voltage when not driven for long periods . !!!

Placed panel on the inside of windshield of my 1999 chevy truck and used the the cigarette plug in for charging source to battery. The cigarette lighter was tested and showed it was a hot connection with ignition key not used. The solar panel was tested and indicated 11-12volts output. Panel was facing East and South. There is a constant battery draw from my aftermarket alarm system and I thought this solar charging panel would compensate for the battery voltage loss, but did not. Usually if truck was not started after 8-9 days battery voltage would drop to 9-10 volts and would not be enough to start truck. Truck was now not started for 14 days with the solar panel installed and truck battery was full dead. Battery showed .05 volts? Had to call roadside service with a high out-put jump starter to start. Disconnected solar panel. Truck now starts fine after 4-5 days on it's own.

Much needed a good solar charging panel for my trailer this unit does the job great

Was exactly what I was hoping for, does a great job of maintaining the battery.

This is my second Powoxi charger. I use them to keep marine batteries charged to start my boat and run a second battery for the stereo system in the boat. The first one has kept the boat starting battery charged all summer and I expect the new unit to do at least as well.

J’ai vérifié bien comme il faut et les lumières indicateurs sont derrière le plastique noir j’avais mal vue et je m’en excuse désolé c’était pas comme sur la photo

Works great easy to use , come in on time perfect for keeping a good charge on the battery ,👍🏻

Seems to bring the battery to full charge after a week or so.
