I've just returned from a week's camping in the Lake District, and this is when I discovered that although my
phone charges from my external battery, my watch doesn't
. I suppose that I should have guessed that its type of charging requires AC, but it was a shame since I would have valued its feedback on days of tramping the fells. I really did wonder what my heart rate reached on some climbs!
Anyway, this is a 'heads up' to anyone who might be away from any AC supply for more than 36 hours or so – take a spare watch (I did).
