    Purchased for my son as a back up for his iPhone. It has a fairly slim profile and recharges phones quickly.

    Bought this brick for a trip. It was fabulous to have. I felt better knowing I had this available if I needed it. It is a tad heavy, but it's worth keeping around.

    5 star because of low price. Nice capacity for the price and small sized. Not a charge rate for devices but it works. For the price it delivers.

    Id like to start off with saying that the product does what it’s intended to do. I get 2 full charges and a half. Really disappointed that it does not come with a wall charger. If youre on a budget go for it but if you can shell a few more bucks id get a better built portable charger. I like that its thin but it looks super fragile.
