As the subject says, my wife just got an iPhone 8 and was looking at the Runsy battery case, there is a version for all models. It's around $35 on amazon although there are 4 different listings at slightly different prices all by the same seller. What really is exciting is the model for 8 7 and 6 has a 5800MAH battery which is a heck of a lot of power. It also charges with a lightning cable so it would probably take forever. I also assume the way of fast charging with a USB C to lightning cable might damage the case.
The more well known Mophie case is around the same price but has anyone used this one? The amount of battery is what really has her considering it.
Thanks for any feedback.
