Lenovo PB 410 5000 mAh Power Bank - Best Power Bank

What is the mAh of the Power Bank?


Power bank mAh - Definition

We often hear the question about the capacity of a power bank. The question goes along the confusing technical term of mAh. What does it mean? What does it stand for? How does it affect the actual capacity of a power bank? In this post, we are going to clarify all those points one after another.

To begin with let me tell you that mAh of a power bank is the technical indicator of the retentive capacity of a power bank. In simple term you can judge the capacity of a portable charger with this measuring unit. Here, mAh means the milli-Ampere-hour and thus comes the abbreviation mAh. If you want to dig in some more, basically it measures how much power it can let flow through it for an hour and the equivalent number in milli ampere. To go with the examples, let one of the best power banks is having a capacity of 7000 mAh, say for the example, that means it have retained a total of charge which is twice than a power bank having the capacity of 3500 mAh.

Portable Power Bank with mAh Capacity

But High capacity power bank, means if a portable charger is having more capacity, that does not mean that the power bank would be able to charge devices which have a larger current drawing ability per unit time. For that we need to ensure that the external USB port of the battery pack is having a higher current rating. But of course, a power bank with higher mAh rating would be able to charge your smartphone more times and for longer time than a comparatively shorter portable power bank.

The greatest problem rather the lack of understanding with the capacity of the power bank is that it is always presumed that a power bank with a certain capacity would be able to deliver all of its power while charging up a device, which is exactly wrong. As, there a considerable amount of charge, for power banks with best quality battery cells like LG or Samsung, would be losing around 10 to 15% of the power.

That means a portable power bank with a capacity of 10000 mAh capacity would be at max can deliver around 9000 mAh or 8500 mAh power. Whereas this estimation is far more less in the case of the OEM portable chargers that are primarily manufactured with the low graded battery cells and are sold at extremely cheap price over online.
