Solar panel on Freerunner back cover

[Ed Kapitein]

Hi Radek,

I was looking for a GPS bluetooth mouse with solar pannels for longer
navigating.
It seems that it is hardly worth the effort, it will give you a few
precent longer uptime and time to full charge would be like days.

Just my 2 cents.

Kind regards,

Ed
