I got these power banks because my phone loses battery power so fast when I am out on the go. In this package you get 2 power banks with cords. They are the color black and are super small, portable and light weight. They are small enough to actually carry them in your pocket. The power banks are compatible with Android and iPhone. What I love best is that they really do love their product and give you a 18 month warranty on them. They hold a nice charge so far. I am very happy with them.
My review is 100% honest and unbiased. All opinions are my own.
