Upgraded 7.5W-Solar-Battery-Trickle-Charger-Maintainer-12V Portable Waterproof Solar Panel Trickle Charging Kit for Car, Automotive, Motorcycle, Boat, Marine, RV,Trailer,Powersports, Snowmobile, etc.

I bought the 7.5W solar trickle charger by Powoxi back in November after parking my car up for storage for the winter. The car is currently in a place where I can't get power to it, so I thought I'd give this a try. In the box is everything you need, and it's simply plug and play. The solar panel is quite compact and offers a good length cable to get to the battery/12v socket. For me it sits ontop of a container exposed to the elements. Now 4 months down the line, I checked the car battery today and is 12.3V which is impressive. I didn't expect the battery to be doing too great, or that the solar panel would last being exposed. It's been buried under snow for weeks, continuously rain on, yet clearly it's still going. The solar panel has done 100% of the work at keeping the battery topped up, at no point has the engine been on or has it been conected to a main charger. This winter had quite minimal sunlight too so I'm quite impressed everything is fine. I'm unsure wether it still works in overcast conditions since I haven't been up to see the LED inidicator on the panel on a day where the sun hasn't been out. Currently at £39.99 this is a great price for what it does. The overall quality is great and obviously it can handle Scottish winter conditions with ease. Overall I highly recommend. Connect it up and it gets to work instantly!

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.

Got this for my Toyota hybrid as battery kept going flat due to minimal use - I plug this to the fuse box connection(the provided positive clamp on jump terminal and negative to engine block) and for last 4 weeks the car has now had no issues and has maintained and charged 12v battery well. When I go to use the car I then use the cigar lighter connection (included) so that I’m still boosting battery while driving about - problem with this Toyota is the outlets in the car are switched off when the engine is off so hence bit of hassle using the fuse box under the bonnet but as I hardly use it it’s every couple of days and doesn’t take long and that’s the car’s fault not the solar panel - but it’s been great and green / red light to show the panel is connected and charging . I used the provided suction caps to attach to inside of windscreen and it’s sticks really well and hasn’t come off but easy to do so when needed - so very pleased with this

Excellent item. Easy to use. Has kept my car battery topped up despite the car being out of use for a month. Used outside, it has resisted the British winter so far. Great value for money.

The best thing I ever bought. Our farm forklift has no charging of battery due to cost of parts, we leave this charger permanently connected and whenever we go startup, the battery is always good, even charges in shade with a little sunshine, and on days when it is cloudy but bright. The charge light on the charger goes green to show it's putting out a charge.

Works well, charge indicator reaction to minimal light levels is confirmed by my solar charge controller as I am using it in a campervan. Not in the most direct lighting position but keeping up with the power drain of alarm etc. Would buy again.

This is a well-made product that's probably fine for many users. I bought it to keep my car battery topped up when not used much over the winter, rather than using a mains powered trickle charger. Unfortunately, it only seems to generate more than 12v in bright sunlight. In winter, with shorter days and the potential for some clouds, added to the fact that my car is kept on the north facing side of the house, it's pretty much useless - only putting out about 6-7v.

I've bought two of these panels, one 7.5W for use in Spain and the 9W for use in the UK. We leave our Ford Fiesta parked at Alicante Airport for up to 3 months at a time. The cigarette lighter port isn't permanent live on this car so I purchased an adapter that plugs into the diagnostic port and it picks up a permanent live there. The 7.5W panel keeps the batter fully charged and ready to go, no need for disconnecting and resetting everything each time. Just leave it on the dashboard and make sure the green light is on (charging). The 9W panel I use on our Audi at this end when parked at Gatwick airport, slightly more powerful as we don't get as much sun. The cigarette lighter is permanently live on this car so need for an adapter. I've monitored the charging and they maintain the battery voltage very well without over charging.

Works well

I read through the reviews before purchasing, and knew about the quality concerns with the alligator clips ahead of time. I ordered one for my Dad's 2001 Toyota Avalon back in really December, which was parked in his driveway in Delaware and barely used due to medical issues and having a newer vehicle available... but he wanted me to start it once in a while to keep the battery charged while he was in the hospital for an extended stay. The cold temps were depleting the battery, and this was just enough to keep it topped off on charge so that it didn't need a jump start. I liked it so much that I ordered a 2nd one for my 95 Grand Cherokee back home in Arizona, which wasn't being used at all while I was in Delaware helping my sister care for my parents and keeping up with their house. When I went to install the 2nd one on the ZJ, the battery terminal on the red top Optima battery was a bit bigger than the Avalon's regular battery and the alligator clip broke when trying to get it on the positive terminal. I knew when I was doing it that trying to get it on the larger terminal and squeezing the clip would stress the plastic and spring, but I did it anyways... and it broke in half. I tried to put it back together, but that obviously wasn't working - so I reached out to the company and explained what happened offering to purchase a new set of connectors. Their Customer Service was stellar, and in top of the immediate apology for my dilemma they sent out a replacement set of connectors which were received that same week. Amazing response time & quick shipment of the replacement negated any complaint that I had with the product - and installing the new alligator clips on the ZJ this time with a bit more delicacy and finesse so as to not over flex the spring or stress the plastic on the larger terminal. I returned back to Delaware after being gone for 5 weeks. The original unit was still with the green light, parked facing to the sun attached to the outside of the windshield - which it had direct sunlight from about 9am to 4pm daily. The old Avalon fired right up like the battery was brand new! I spent a month in Delaware, and after getting back to Arizona I tested the ZJ - also parked facing the sun with the solar charger attached to the outsiden of the windshield and getting direct sunlight from 7am to 5pm. The 5.2 liter V8 fired right up with no lag like it was still being driven daily. I'm happy with the product quality and performance, and highly recommend it for anyone who has a secondary vehicle that doesn't get a lot of use to avoid the frustration of discharge and having to jump start.

Works great, using for my ride on mower, keeps the battery charged. But cord could be a bit longer. I wouldn't rely on the suction cup too much better to use screws

取説が英語表記でLEDインジケータの意味がよく分かってないけど充電は出来てるようなので、安いしいいかも 耐久性は今のところ不明

Fast Shipping, good quality. Does the job but I might buy the next one up for a few extra watts.
