Greetings Mac Rumors! Today while at the mall i was asking questions about the mophie juice packs and was informed from numerous sales men including friends that when plugged in it charges the phone first then the case. Unless i remove the phone from it to charge it. IN this case i want to know is it safe to buy these "cheapies" off ebay for like $20? Ive heard of them burning you if they get too hot in your pocket or even damaging your iPhone. As a university student i have not another $100 to pamper my iPhone with. Its an iPhone 5 This one here looks really nice. A switch an extra usb 1000 times charges and a 4200 may battery for like $20.. What do you think?
