Bought 3 of these when Pokemon Go first came out, it doubled the screen on time of my Nexus 5 which has a 3000mAh battery. These are really compact, and look cool since they are colored like a Duracell copper top battery, great for travel and for keeping in the car as a backup. NOTE: if you leave these in your car, keep them away from the sun and in a cool place.

I got this power bank since I wanted a small sized power bank that I can easily carry around. The design caught my attention since it has a unique design that looks like a Duracell battery, compared to other designs I've seen that are blocky or have a generic design. It charges my phone fine, although I would have preferred a larger capacity, but this works fine for me.

It worked really well up until I lost it. Was able to give me almost two phone charges and want extremely bulky.

Picked up two of these for backup on the Harley. We take a lot of long road trips, and these are great for backup power. Easy to forget they're in your pocket, because they take up so little room and are so lightweight. We get about 1.5 charges out of them, for our I-phone 6's. Highly recommended

Very good device as power bank and quickly charges the mobile and micro USB to USB cable is compatible with all other devices. Easy to use and no extra care is required , durable to other power banks
