This item could not keep a charge on a battery in a Lincoln LS that has lots of features that drain the battery over a few days….left car in Airport 4 days and battery was dead…the battery is new and will take a full charge and stay up if driven daily…bought this item hoping to solve the problem…no luck…..I’ll try it on my garden tractor…

Solar panels always have a set of specs such as Open circuit voltage, Short circuit current, and an operating current at a particular operating voltage while being illuminated with a standard luminous flux.
Nothing like that is given and in fact I can only get a maximum of 3.8 watts out of this panel at high noon during the summer. The comments on here questioning the weather resistance is worrisome. Amazon should pull this product.

Used too keep a battery charged on an outdoor stored ATV, just like the picture on the packaging, after the winter months it stops working. I try to troubleshoot the item and the screws holding the body together have plastic caps over them. Upon trying to pry out the glass breaks on the solar panel. My suggestion for Coleman if making an inferior product make it easier to repair. Do not buy if plan on using outside.

I’m not sure item works. It could be too small for what I am using it for. I’m trying to use it as a trickle charger to maintain a battery in our camping trailer while it sits idle over the winter. It may be too small for this job. The less than one year old battery is not maintaining its strength with nothing running.
It is currently not connected directly to the battery but through a cigarette lighter type outlet inside the camper. Charger sits in the window of the camper facing south all day. I may try direct connecting it to the battery and placing charger outside camper (in the weather) to see if that makes a difference. If it doesn’t, I guess it was a waste of money.
ps: The only thing running off the battery is the smoke/CO2 detector.
