Nearly 100 Dollars is a good price considering its performances and wattage.


The solar panel doesn’t have the wattage to do a complete recharge a deep cycle battery in 1 day. One of the drawbacks of this panel is that most people have noted a discharge on the battery after the charge indicator is off, even though the connected devices are either turned off or not plugged in. To avoid this battery drain the solution is to add a switch.

    I noticed the other Coleman indicated that it wasn’t for outdoor use (??). How is this one? I plan to mount it to my VW bus to charge my second deep-cycle battery that powers a thermoelectric cooler, some fans, etc. Is 18W enough power for this kind of thing? Can you compare quality of Coleman to the 15W Sunforce? I’m looking to spend <$100, so these are appealing options, please let me know if I've overlooked another brand.
