This power bank is amazing! I've used it to charge my n phone and tablet. I get about 5 charges if it's fully charged! Meaning it will fully charge my phone 5 times before it has to be recharged itself. My husband has used it on his pc he used it for 2 days without having to recharge! I love it! I only wish it included a usb with the charger. Instead of a double sided c charger.
