Output of the Mobile Power bank

That’s mean charge your mobile phone or other digital devices such as iPad through your best power bank, the output current of power bank charger normally is 2.4A or 2.1A & 1A, some few items have 5V 3A output for a quick charge.  Usually, one power bank has these output current same time to make it easy to use and charge different devices at same time. The specific output charging current that the mobile power supply can provide depends on the device being charged. For example, the iPhone 6 can accept 2.1A input current, if you use the 2.1A USB output of the power banks can charge faster than 1A output port.  from 0%~ 100%, the charging time will be shorter. When there are multiple outputs on a power bank, it is common to find 2.4A, 2.1A, and 1A outputs together. With simultaneous charging across all three of those ports, all devices, no matter their charging amplitude, can power up.

Battery capacity of the Portable Power bank

Do you have such confusion? The battery capacity written on the mobile phone power bank is 10000mah, but why do you need to recharge it after using several times? Example, iPhone 6 battery capacity is 1810mah, so it can charge 7 times from 10000mah ? in fact, it can charge 5-6 full times. Here you need to consider the efficiency issue: Although the mobile power pack is marked 10000mah, the power will not 100% converted to electricity to your device. This is due to the working environment, battery quality, etc., which will cause power loss. When power is transferred, there is always loss due to resistance. Power Banks are not able to transfer 100% of their actual capacity to a device, so we factor in this loss when calculating how many times an average device can be charged from a fully powered Power Bank of any given size. Efficiency ratings differ between Power Banks based on their cell type, component quality and environment. Ratings between 80% and 90% are the current industry standard. Beware of suspiciously low-cost options claiming high-efficiency ratings.
