Unfortunately, the battery is not useful for me. I invite him over the normal mains supply is no problem. It delivers what it promises, however, it is not suitable for solar equipment. Have connected it to a solar Gorilla and the first time he has also charged. When he was full, he, however, did not stop blinking. Since the charge, the LEDs in the clock flash and are already almost 2 weeks: /
Not compatible with Solargorilla (and possibly other solar panels)!
