    WARNING: the instructions indicate that the panels can put out 12v DC to your battery bank or power convertor. This is a TOTAL LIE. the coaxial connector puts out the 19-22 volts DC that comes directly from the panels. So if you connect a device that is a battery charger which has a limit of 13.5 volts DC (typical of most battery chargers) you will burn out the device.......this is what happened to me. Panels burned out a $200 DC charger for car and airplane LiPo batteries. So YOU MUST use a voltage regulator if you will hook any device to panels that cannot accept up to 23 volts DC in an initial startup pulse. You can find a 300W regulator on both Amazon and Banggood that will work fine. Aside from that problem, the panels work very well and do yield 150watts output in noon day sun in California. The USB connectors do output regulated voltages. I was amazed that even after sunset I was able to get roughly 30 watts into a battery vault. Let us hope the panels have a long life. tjcooper
