Solar-Powered Lifesaver with a Few Flimsy Flaws
I recently tried out the POWOXI Upgraded MPPT 15W Solar Car Battery Charger & Maintainer, and here’s my take:
This solar panel does what it promises – it keeps my car battery charged efficiently. The built-in MPPT charging controller is a nice touch, ensuring optimal charging.
The instruction booklet is very good though more than comes with most, however I am not sure how needed it is.
However, the suction cup design didn’t quite win me over. I found it a bit flimsy and would much rather secure it with screws for better stability. The plastic housing also seems like it could become brittle over time, which is a concern.
There are more robust options out there, like those epoxy-covered solar panels, which might be a better pick if durability is a priority for you.
Overall, the POWOXI charger works as advertised and gets the job done. I’m giving it four stars for its functionality, but with some reservations about its long-term durability. 🌞🔋🚗

A little pricey – suction cups have to be clean and the glass too to hold well
I ordered this to just leave on some of the vehicles that I don’t use that often in my yard to keep the battery charged without having to run a power wire and charger to them.
This does do a good job of providing charge to the battery when the sun it out. There is more than enough wire from the panel to the connectors but I do wish the different connectors had just a bit more wire. I plan on using the permanent installation one on my side by side and just swapping the panel around.
I put this on a pretty weak/dead battery hoping it would charge it and it did at first but then it quit when I messed with the car key. It works fine on good batteries but everything is smart charge now days.
The suction cup feature is a neat idea but you do have to clean the suction cups and the window or they will not stick. I am thinking about putting some magnets on it to just hold onto the metal of the car easier and not have to mess with the window.
It has indicators to show when it is getting sun, charging, and complete. I have yet to see the fully charged light yet and it has been charging for 4 days when the sun is out.
Overall, this is so much better than having power wires and chargers in your yard and I like it has different connectors for charging (to include a cigarette lighter one). I thought it was a little pricey but the solar panel is not a cheap one so it might be on point.
