The Changers solar panel, power pack/data logger and community is an interesting concept and, I think, a well designed product. Lithium battery charging and solar power don’t fit together easily but when they do you have the potential to get a powerful and lightweight solution. The equipment arrived today, it’s in working order and over the following weeks i’ll be doing some testing.
The ultimate aim is to have a new set of equipment for a second solar computing tour. On the last one, in 2007, I had a mobile PC, a lead-acid battery and a 25W panel. Total cost was around 1500 Euros and the weight and size was too big for travelling. If the Changers equipment works we’ll have a much smaller, lower-cost solution with a built-in data logging capability. There’s the fun aspect of the Changers community too which could encourage the user and help spread helpful information, tips and tricks.
