Smartphones have batteries that run out faster that the batteries of older, less optimised models. Most people use phones these days to keep up with their mail and a million other tasks.

Which is why you need a power bank.

Many power banks like the Mi power bank in India try to keep up with the increased usage of smartphones by upgrading their products. The power banks have to be able to accommodate this excessive use of the phone, which is why, today, power banks have many designs and better capacities. Choosing the right power bank is important so that you’re able to work well.

But to do this you need to understand a few things about them. 

Charging Your Power Bank

Power banks have a dedicated input socket that is used to receive power. While you can charge using a USB socket on your computer, using a wall socket adapter is much faster.

Depending on the power bank’s actual capacity and the current charge level, it can take some time to fill up. For larger banks, the time taken can be doubled or even tripled compared to the regular ones. They come with both an LED indicator and a safety cut-off to show when they need charging or to prevent overcharging.

To ensure the efficiency of your power bank, make sure that it is not overcharged.

How Long Will Your Power Bank Last?

The more expensive power banks can for a really long time, while the cheaper ones may fall short. Their longevity is dependent on how they’re used.

Power banks are generally not used daily, so they last longer than 18 months. A good power bank will last for around 3 to 6 months. The lower quality power banks may struggle to keep charge for more than 4 to 6 weeks.

Most of them slowly lose efficiency over a period of time due the influences of the environment and the way they are treated. For example, leaving it in the car where the temperature fluctuates shortens the lifespan of an average power bank.

How Should You Rate Your Power Bank’s Efficiency?

Power banks are generally not able to transfer their entire actual capacity onto a device.

This needs to be factored in when you calculate the given capacity of your power bank and the number of times your phone can be charged from it.

Will Your Power Bank Face Device Depletion?

Of course.

The lower your device’s power is, the more the bank has to charge it back up to 100%. You should consider the charging from 20% to 90% as a full charge, because the effectiveness of the power bank decreases from this point on, leading to a wasted charging potential.
