I am going on a vacation in Yosemite for 5 days, i'd like to know how well do you think an iphone solar charger will work. whats your experience with these.
Or bring a back up charger the one that already charged, all you need is to plug your iphone in it and it will charged it. Worked for camping if you do not have your car or no electrical outlet nearby. They worked pretty good for me. Make sure it is made or compatible for iphone.
