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.

Need to know how far away I can place the panel from the battery** A: The main cord is 8ft. long with the the two connecting cords, ie, one to use when connecting to the battery and one to use when connecting through the cigarette lighter are about 15" each. I'm sorry it took so long to answer your question, it has been raining and my van isn't under cover. Hope this helps you. **Q: Can i just connect the black and red clamps directly to an electric fence? Or do I need anything else?** A: You just need to connect the sun to the alligator clips to the battery and the other end sae head to the solar panel. **Q: can I use this for light in my barn** A: You could if you connected it to a small 12v battery and used some of the 12 LED retrofit light kits they use for the interior of cars or an 12v led strip. I'd suggest maybe a 12v CCTV battery to make it affordable. Unless you are talking about large amounts of light, then you probably would be better off with some kind of pre-made solar light kit. **Q: Does this unit have a charge profile controller for lead acid batteries, they prevent over charging & shut down the current as battery approaches 12v?** A: It has no controller. But if you charge small batteries, you need a controller. If you charge a large battery, you don't need a controller because its current is relatively small and it won't cause overcharging. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Brilliant Little Solar Charger – Kept My Truck Battery Topped Up for 6 Weeks! *by L***T on 9 October 2025* 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.

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. ## Frequently Bought Together - POWOXI Upgraded 7.5W-Solar-Battery-Trickle-Charger-Maintainer-12V Portable Waterproof Solar Panel Trickle Charging Kit for Car, Automotive, Motorcycle, Boat, Marine, RV,Trailer, Snowmobile, etc. - OYMSAE 12Feet SAE to SAE Extension Cable Quick Disconnect Connector 16AWG,for Automotive,Solar Panel Panel SAE Plug(12FT(16AWG)) - SUNER POWER Waterproof 12W 12V Solar Battery Charger & Maintainer Pro, Built-in UltraSmart MPPT Charge Controller, 12 Volt Solar Panel Trickle Charging Kits for Car Automotive Boat Marine RV Trailer --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.hr/products/360905535-7-5w-solar-battery-trickle-charger-maintainer-12v-portable-waterproof](https://www.desertcart.hr/products/360905535-7-5w-solar-battery-trickle-charger-maintainer-12v-portable-waterproof) --- *Product available on Desertcart Croatia* *Store origin: HR* *Last updated: 2026-06-23*
