Hey y'all.
I'm taking a six-month trip to Europe starting this June. I'll be bringing my iPhone with me. For a portion of time I'll be backpacking through the Alps. However, I won't be spending too much time away from civilization - do you think a solar charger is necessary? I was looking into them because I was worried available outlets might be sparse (I don't know how protective cafe owners are over their electricity).
Thanks.
