Initially I thought my Edge 800 was a waste of handlebar space with regards touring. Here in Australia many towns are days apart so there were no charging options. Now I have an E-werk with cache battery (with my Sondelux) so my Garmin is always charged/charging and its finally useful. I was so sick of sitting in caravan park laundries or bathrooms for hours trying to get everything charged up it was seriously detracting from my enjoyment of touring. Now I'm a very happy camper!
