A battery pack from an extremely reputable company. A high quality piece of tech that offers convenience in charging. Instead of having to carry 3 different products (a battery pack, a cord and your phone) you have a single device with a battery pack that’s attached to your phone. I sell furniture and there’s a lot of down time so I spend a lot of time on YouTube and playing mobile games. I work from 10-6:30 and by about 3:30 my phone is giving me the 20% notification. This product will give me the boost I need to get through the day and I won’t have to fumble around with a cord, battery pack and my phone. Nobody wants a cord hanging out of their pocket with a phone and a battery pack stuffed in their pocket. Give Anker a break. This is a first generation product from Anker and Apple is probably far from releasing their MagSafe battery pack (if it’s ever released at all). Anker is doing something Apple hasn’t achieved yet and may never. Sure this first iteration seems a bit rushed but there will be improvements made on later models. At least we have something like this to experience and use. And for some, (like me) it may be just what they need to get them that last little push they need to get their phone through the day and in a nice little magnetic package at that. 5 watts? So what. It charges and does it’s job.
