Review: Brilliant Little Solar Charger – Kept My Truck Battery Topped Up for 6 Weeks! - 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.
Review: Good battery maintainer - Surprised by the effectiveness of this little solar panel. Used to maintain the battery on my Audi A8, as the car is infrequently used. This won't recharge a flat battery if it's dead but will restore one that is slightly down or not used for long periods. Easy to use and well made produces 13.2 volts in overcast conditions I'll up date voltage when in full sunlight once we get a clear day. Connections are very tight to plug and unplug so be careful with them. Overall very happy with the unit.
