POWOXI 20W Solar Panel Kit, 12V Solar Battery Charger Trickle Maintainer + Upgraded 12Volt 8A MPPT Controller + Adjustable Rack with Corner Protectors for Car, RV, Trailer, Boats, Motorcycles

This thing really works. kept my tractor battery charged all winter. I'm probably going to get another one for my generator.

Works great. Keeps tractor and ATV batteries charged.

Works as advertised, rugged so far

The first solar panel and bracket I received arrived without screws or bolts, so there was no way to mount the bracket to the solar panel. That unit was useless without those parts because it couldn't be propped up or mounted. The manufacturer or distributor, "POWOXI," was initially unreachable directly for any customer service. My only option was to ship it back, request a refund, and what a pain that all would have been. All that time and energy when I only need two proper screws. Through some trial and error, I was finally able to get a message to "POWOXI" through Amazon's Customer Service, and "POWOXI" responded with a message that they'd send me a replacement unit. They did, and the replacement unit came both with the bracket screws, washers, and wingnuts, and it also came with anchors and screws for mounting the bracket to another surface. The replacement unit works well. My only complaint is that the basic charger that's included doesn't give any information about state of charge. Only that it's "charging" or "charged." Still, all in all, I'm now happy with the quality, and I appreciate that "POWOXI" did what they promised.

Works great and easy to install. Different ways to set up. Attach to something or simply put on top of something. I use it for my rv.

Is this supposed to come with a Charge Controller? Maybe that is why its not working. four hours in direct sun light and the cell phone battery got weaker. If anyone can help me figure this out it would be gratefully appreciated! Thanks for sending out the first control box (Not a "replacement", the first one was not sent in the package). Once I receive it and know it works I will change my review to a much more positive. Thank you, again!

Charged a battery one time. Idk if I touched the wrong terminal or not but, it’s junk.

It comes neatly packaged to prevent damage to the panel during shipping. It is a decent size for travel. Good value. The cables are a good length to reach the battery to deliver a trickle charge. It does what it says.
