This was an excellent buy for my holidays.

Fits in the palm of my hand. When fully charged it puts enough charge into my S7 edge take it from empty to 50%. Really happy with this product. It comes with a charger lead and a dinky little carry bag. Charge from mains to fill the power core and when needed conect to phone, tablet etc press the end the connector goes into and a green light comes on to show you are charging your phone. A red light comes on when the power core is empty.
Not sure how long the power core holds full charged when not in use.
