Charging A Garmin Instinct With an External Solar Panel
Yesterday, out of curiousity I experimented. I charged both the Garmin Instinct Solar and the Garmin 45s with a solar panel. The first thing I noticed is that they were using 0.1 amps to charge, rather than 1, 2 or more amps of power. Until this experiment I had never considered how small batteries for gps watches are.
200 mah According to a Google search the battery capacity of GPS watches is around 200mah.
