  • Great folding solar panel for DIY
    Verified Purchase

    Note: I've only tested and used the fold-up panel itself and not the charger that comes with it. Voltage and current specifications were missing from the product site, so I took a chance on this 40 watt fold-up panel. I tested the open circuit in full sun with a multimeter and the measurements added up so I even ordered a second one! As I mentioned above, I haven't used the MPPT battery charger. These panels are for recharging my offroad vehicle's auxiliary battery when camping and I already have a high-end battery charger. Hence the intended purpose, having 40W of PV that can fold into the size of a ream of paper is great!
