Why an external power bank, whose typical capacity is the same or slightly higher than device's one, can't fully charge a phone?

What’s more, a battery cell is only 3.7V and in order to charge a smartphone or portable device, the voltage has to be raised up to 5V. During his process, there will be some capacity loss as well. At the same time, there is also energy loss when the built-in battery of device charges the device itself. What’s more, there is also power consumption for standby power.
