POWOXI Upgraded 7 5W-Solar-Battery-Trickle-Charger-Maintainer-12V Portable Waterproof Solar Panel Trickle Charging Kit for Car Automotive Motorcycle Boat Marine RV

So far so good. I have this sitting on the hood of an 81 Toyota pickup for the past 3 weeks in Phoenix. It has dealt with the heat no problem, made it through two thunderstorms, and has kept the battery topped up. I usually start the truck once every weekend, and let it run for an hour or so to charge, so this saves me the trouble. Easy to use, plug and play essentially, just stuck it to the hood, and ran the wires through the front grille. For as inexpensive as it is, it has held up well. Indicator light is difficult to see during the day, but works properly. And most importantly it has not overcharged, or discharged the battery. Read more

I was skeptical about this battery tender so I waited to write a review, so far this thing is a beast. I am using it on my skidsteer and so far, so good. The suction cups keep it secure even when running full production, the machine fires right up on cold mornings without any lag. Also solar panel has withstood the Arizona sun. I am ordering two more for the boat! Read more

Works great. Added magnets to the bottom to secure on my skid steer Read more

I bought this to put on my 4 wheeler just to make sure the battery stayed up. But instead put it on a tractor. It worked great, it hadn't run for a couple months and it fired right up. I like the size and how well it worked, I ordered 5 more. The only thing that could make this better is a pigtail that bolts on to the battery also. Read more

This solar panel trickle charger is a life saver. Bought it for my truck I wasnt driving much but has a gps tracker that leaches the battery dead over 3 days. This thing maintains a full battery charge. I don't know about the 12v plug it comes with I just use the battery clamps only. In direct sunlight in summer it was outputting 16v what tester said but it definitely keeps my battery from going dead due to the tracker. Woupd definitely recommend it. Read more

This has works absolutely perfect so far, we stored our snowmobiles and side by side in an outbuilding that has no electricity at the end of the season, they fired right up! Pretty straightforward setting up and great value for price paid. Would recommend. Read more

I purchased this solar panel for my cellular trail cameras to charge the external 12 volt battery. Worked flawless, do I purchased another for a different camera wired it the exact same way and light on the solar panel is always red never switching to green. The second solar panel must be defective. Read more

I was skeptical about buying a solar powered charger but this actually works pretty good on keeping my dump trailer battery charged. I will be buying another soon for my other trailer. Read more
