This powerbank is in 20000mAh can charge the phone more than twice and it also have a two output can charge two phone in the same time. It also very resistant, I use almost 4years but still very nice not even have a problem

I’m the iPhone 6s user. This phone that I like is the processor is excellent, it won’t be lag when playing a 1080p game. have a lot of functions that I like too is Siri. Siri help me a lot of things, such as remind me to do things. If you need to buy a phone choose iPhone 6s!
