5 Factors That Might Affect the Efficiency of Your Powerbank

Find out the factors to observe on how long your power bank will last under different circumstances on this article.

Choosing a power bank is a complicated process, especially when it comes to deciding how long it will last. Fortunately, this decision is not as difficult as it may seem. By observing several factors, you can predict how long your power bank will last under different circumstances. 

Below, we’ll discuss these factors one by one:

1) Device Capacity

Higher capacity power bank = more charging time per unit of energy.

If you want to charge your device faster, you should look for a power bank of higher capacity. This means that the power bank is able to store more energy, which in turn means that it is capable of charging your device to a higher percentage.

Let’s say you have a power bank of a typical size, with a typical charging capacity. With this power bank, you can charge your smartphone from 0% to 100% within 4 hours. If you increase the size of the power bank, you can charge your device even faster. 

2) Phone Battery Capacity

The phone’s battery capacity is perhaps the biggest determinant of its battery life. This means that if you have a phone with a higher capacity battery, you will be able to use it more before it runs out of battery.

The higher the phone’s battery capacity is, the more hours your power bank will charge it.

3) Telephone Energy Usage

Different phones consume different amounts of power, which is why it is important to consider how this factor will affect or power bank’s battery.

For example, iPhones are a bit more power-hungry than other phones. This means they will require more energy to charge to the same percentage.

Lower-tier phones typically have smaller batteries and consume less power, which is why they do not need as much energy to charge.

4) Device Power Usage

Devices also consume different amounts of power. Your phone has a battery, which consumes energy to allow you to use your device.

Because power banks typically have a fixed charging capacity, different devices have different charging times. For example, larger devices will require a power bank that has sufficient capacity to charge such devices. 

If you have a large-sized phone, you will need a power bank of higher capacity so you can charge it at a decent speed.

5) Electric Current Output

Electric current is the flow of electrons through a conductor. When you need to charge your device, the power bank generates electric current that is transferred to your device.

In general, a power bank will charge your device at its highest current output. This means that your device will charge at its highest speed.

However, you might find that some power banks offer different charging speeds. If you are using a power bank that has a lower charging capacity than your device, you might want to select a power bank with a maximum charge current of 2A. 


In the end, your main goal should be to choose a power bank that has a high charging capacity to power your devices. In addition, you must consider how long it will take to charge your devices.
