I have been using this for a week now and love it, considering getting another one.
We have a Set power PT45 fridge/freezer, we use it to run this when solar charging our other batteries and or to charge our multitude of devices, it charges quickly whether ac, dc, or even solar, we plug it into one of our 100 watt panels and no problem. Charges from near empty to full in a couple of hours, a bit longer when over cast, but not much considering the capacity, in 70 degrees it may run our PT45 overnight.
