its bigger than i expected. the same size as my moto g stylus but thicker. it charges my phone rather quickly even while im still using it and the charge on the pack lasts several days for me. i enjoy the digital display because i know exactly how long i have left on the pack. i use it at work (12 hour shifts) and can charge my phone every night im on shift and still have roughly 30-40% left after a 3 day set. i highly recommend it.

An amazing value.

You won't regret buying this! The last time I had a power bank was 10 years ago… let me tell you this is such an improvement from what they once were. I have an iPad and my iPhone, they both have a large battery capacity, yet somehow this can charge my phone 3 times and still get my iPad to roughly 50 percent. It charges quickly and I would recommend, especially if you hate always being connected to a wall.

OMG, Y'all, i read the reviews, i was hesitant to get this based on reviews. I'm so glad i got this. i charged it fully, and then i took it to the pool. it charged my earbuds and my phone twice (i was listening to Pod casts both times). I'm at the pool 4 hours per day..what a great little charger
