A:AnswerI notice a lot of people complaining that it doesn't charge their phone 3 times like it says on the box. Well when this device came out the newest iPhone was the 5 and 5s and that phone it will charge 3 times. The iPhone 5 and 5s have approximately 1500 mAh batteries and this battery pack is rated at 5000mAh so you will get 3 charges. But if you have an iPhone 6 Plus that has the 3000mAh internal battery it will only charge it once. It completely depends on the phone itself. That's why you go by the mAh rating. Just look up the battery size of your phone and you'll know from that number.
