Good value, works as intended.
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.

KEEP IT ENERGIZED! ⚡️
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!

Awesome.
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.

Awesome Battery Maintainer
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.

Would recommend…sleds fired right up!
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.

Good solar panel
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.

The build quality is impressive, with a durable and weather-resistant design that ensures longevity. I love that it's environmentally friendly, harnessing solar energy to keep my battery charged. It's perfect for those who don't drive their vehicles daily or for extended trips where access to a power source may be limited. Overall, the POWOXI Solar Battery Charger has exceeded my expectations in terms of performance and reliability. It's a great solution for keeping your car battery maintained and ready to go.

Before heading off for a six-week trip over Christmas to visit friends and family in Australia and New Zealand, I realised I had a small problem — I’d be leaving my truck sitting idle for quite some time. Anyone who’s dealt with a flat battery after a long break knows how frustrating that can be, so I wanted a reliable way to keep the battery topped up while I was away. After some research, I decided on the Upgraded 7.5W Solar Battery Trickle Charger Maintainer – 12V Portable Waterproof Solar Panel Trickle Charging Kit. It looked like the perfect solution: simple, compact, and completely self-sustaining. A lot of online advice suggested just plugging a solar charger into the vehicle’s cigarette lighter socket, but when I checked with Ford, they advised against it — apparently, in my model, that port isn’t live when the ignition’s off. So instead, I followed their recommendation and connected the charger directly to the battery. The setup was straightforward. The kit comes with crocodile clips for easy connection and a generous cable length that easily reached from the battery to the inside of the truck. The included suction cups can be attached to either the front or back of the solar panel, so I mounted it neatly on the inside of the windscreen, where it could catch the light without being obtrusive. The cable is thin enough that the door seal closes perfectly around it, leaving a discreet and tidy setup. While I was away, I didn’t have to give it another thought. The solar trickle charger quietly did its job, keeping the battery topped up day after day. When I returned home six weeks later, I unclipped it, turned the key—and the truck started first time without so much as a flicker. No power loss, no sluggish start, no hassle. The build quality feels solid, and the performance exceeded my expectations. It’s weatherproof, easy to mount, and perfect for anyone who leaves their vehicle parked up for long periods—whether it’s a car, truck, camper, or boat. I’d just advise checking your specific vehicle setup before installing it, as not all models allow charging through the same method. Once you’ve got it right though, it’s brilliant. All in all, this solar trickle charger is one of those practical, inexpensive tools that just works. It’s saved me time, stress, and probably a few jump-starts down the line. Highly recommended for anyone who wants peace of mind while their vehicle’s sitting idle.
