The battery was able to charge my iPhone 3 times before needing to be charged itself. The battery itself took about 16 hours to charge. Overall it worked how I'd expect a portable charger to work. My only issue would be the lack of color but that is just an aesthetic critique.

Good powerbank. Slim profile. Should be easy to use with travel. Its a bit heavy but should be manageable to use.

Sizewise it is not like your phone but more like a notebook.

Looks quality product but very big,looks like a tablet
