POWOXI Upgraded 20W Solar Battery Charger Maintainer, External Smart 3-Stage PWM Charge Controller, 12V Solar Panel Trickle Charging Kit for Car, Marine, Motorcycle, RV, and More
If you’re after an easy way to keep your car, motorbike, or even your boat ticking over, the POWOXI Upgraded 20W Solar Battery Charger is well worth a look. Built with a tough-as-old-boots design, it’s spot on for keeping your 12V batteries topped up—whatever the British weather throws at it. The latest 2024 model comes kitted out with a 20-watt monocrystalline panel, so it doesn’t faff about when it comes to soaking up the sun’s rays, even on those cloudy days we know all too well.
What really sets this charger apart is its clever external 3-stage PWM charge controller. This bit of kit delivers up to 30% more efficiency than your bog-standard models, making sure your battery gets exactly what it needs—no more, no less. It’s all managed by a smart microprocessor, so your battery won’t be overworked, and you’ll squeeze the most life out of it all year round.
There’s also a handy USB port, so you can top up your phone or other gadgets straight from the solar panel—perfect if you’re off-grid or just can’t be bothered rooting around for a plug socket. The body’s made from tough ABS and PC, so it’ll take a few knocks without looking worse for wear, and the LED indicators give you a quick heads-up on how your battery’s getting on.
Safety-wise, you’re well covered. There’s built-in protection to guard against overcharging, overvoltage, short circuits, and even if you accidentally connect it the wrong way round—so you can plug in with peace of mind. And with a 12-month aftercare service thrown in, you’re not left in the lurch if anything goes pear-shaped.
