Does anyone recommend a portable powerpack for 2 iPhone 6s? I am not entirely interested in the big mah 2 usb port ones because there are two people involved here and I'm not necessarily sure it would be best to tied to one hub. I'm sort of into the Anker Astro E1 5200mah candy bar size but two get two of them would be kind of weighty even though one could charge two. Two of the Anker Powercore+ 3250mah lipstick sized chargers seem kind of good and portable but I don’t know. What do people use?
