Pretty much every traveler I know (especially iPhone users) finds keeping their phone charged a real and constant challenge on the road. The TravelCard is a portable smartphone charger that fits in your wallet and gives you an additional five hours of talk time—so while it may not solve the problem entirely, it could be a huge help. It works for iPhone 5, 5C, 5S, 6, and 6 Plus and Android. It’s currently retailing for $39.
