The Casio Lineage and Eco Drive arrived today. Put them outside this evening for about an hour. The sun was already low in the sky and it was cloudy, so they did not get much of a charge. The Casio arrived displaying "med" and the Eco Drive was dead. After being out for an hour the Casio was still on med and the Eco Drive's power reserve barely moved and the second hand was moving every 2 seconds. Decided to use this LED work light to charge more. Did not expect much. But the light surprised me! After just 4 hours, the Casio was on HI and the Eco Drive was reading over 1/2. Here's a link to the light. l mounted it to a camera tripod.
