I’m curious, has anyone ever used one of those portable Solar-Powered Power Banks to charge their OP-1 while out on their travels? If so, which model, under what weather, and how long for a full charge?
Due to the nature of solar and weather conditons, I realise any info provided could not be too accurate. The battery in the OP-1 is said to last for up to sixteen hours, but it has to be fully charged to reach that so it really is just a ball-park figure question.
