Review by weBBed for Coleman CL-100 72000 1.5-Watt 15-Volt Solar Panel Battery Trickle Charger

I almost didn’t buy this because of the 1-star reviews — but then I noticed those reviewers were just ignorant. (Uninformed Amazon reviewers?!, gosh what a shock…). I used a fuse tap to install an always-on 12V cigarette lighter adapter in my SUV for this panel. The low voltage trickle is enough to keep my battery topped off indefinitely, even after 2 and 3 weeks of just sitting in the driveway (whereas my battery would sometimes be almost dead after sitting for a week). Almost bought the 5-watt unit for twice as much, but this is half the size and turned out to work just fine.

Regardless of what the Amazon listing says (and I asked them to change it over a month ago and still haven’t) this product is NOT weatherproof. When you open the package the literature about the product specifically states that it is “not for use outdoors”. You have to pay more to get a weatherproof model.

Review by M. Yeager for Coleman CL-100 72000 1.5-Watt 15-Volt Solar Panel Battery Trickle Charger

This product was purchased to maintain the charge on a battery in a vehicle that is seldom driven. It works fine. Please note that it is not designed to charge a battery that is low, only maintain the charge. If you need a charger, consider a model that produces more power (watts). The unit is fairly small and has an LED to indicate it is producing power. I would buy it again.

I purchased one of these in the hope it could trickle-charge a car battery over a few days. It won’t. It produces such a small current in full sunlight that it can only maintain the existing charge of a battery. If you have a flat battery and you leave this plugged in for a few days, you’ll still have a flat battery.
