The capacity of 5000 mA / h allows to fully charge a half times a high-end smartphone, or add several hours of battery life in a tablet.
The battery is surrounded by a glossy black plastic shell of good quality, workmanship is normally treated. It comes with a USB / MicroUSB a little short (20 cm), but this is probably to limit energy loss during charging.
I find it a default format. It is a little heavy and a little big to fit in a pocket .. it looks like a lipstick tube, but in fact it is bigger than a tube of glue. It will be better to have it in a bag, but in this case, so take a battery of 10,000 mA / h which will offer more autonomy in volume and weight equivalent, for a price barely higher.
The current price of 13.99 in promo is more than adequate, the "normal" price of 39.99 is totally delusional.
