Then if the phone has a 3000mAh battery, you would need at least 10000mah power bank.

The devices can charge your phone fast, but it depends on many factors – capacity, USB types, device capabilities and many more. The more capacity your device has, the more time it would take to charge it.
Number of Ports
The number of ports of the device, are important if you have several devices and want to charge them at the same time, or if you want to share it with your friends. This way you can all enjoy your cell phones or tablets without worrying about energy. Just make sure to charge your power bank completely and make sure to calculate the capacity of the batteries and power bank itself.
