Things to Consider While Buying a Power Bank

There are things you should know about power banks so that you can choose the correct type of power banks according to your requirement. After reading this section you’ll be able to find the right one.

Power Bank Capacity

The foremost important thing is, of course, its capacity. The capacity of the power bank is the most important thing that you should first look for, to measure the capacity of the power bank you first have to know the unit of measurement. The power of the battery depends upon the capacity of charge it can hold and it is measured in mAh(milliampere-hour).

You have to make sure that the power bank has more mAh then your smartphone battery capacity. For example, let’s say a smartphone has 5000 mAh battery capacity, so to charge the 5000 mAh battery a power bank of a minimum of 6000 mAh should be needed. Usually, the price of the power bank increases with the capacity of charge it can hold. More mAh means more juice.

Before you buy a power bank check your device battery mAh capacity after that decide how many times you want to charge your device with a single charge of the power bank.

Let’s say you have a device of battery 1000 mAh capacity and you want to charge it 5 times with the single charge of the power bank, then a 5000 mAh power bank will be required.

Always try to buy higher-capacity power banks then the exact capacity you would want, as due to transmission loss power banks lose some amount of charge through the leakage. Usually from a 10000 mAh power bank, you’ll get 6000 mAh.

Voltage and Ampere Reading

Apart from the mAh capacity, there are other factors that largely matter when it comes to fast charging and slow charging. Such as Voltage and Ampere power. Depending on the type of device you want to charge the time for charging will vary. For example, let’s say you want to charge a phone which supports fast charging and the requirement for the fast charging is 5V, but if the power banks have only 2V output then the device will charge slow. Modern-day Android phones usually come with 2V to 5V and 1.5A to 2.5 A, so you should consider purchasing a power bank that provides the flexibility of charging the fast charging supporting smartphone.

Size Matters

Power Banks should be portable so that you can carry it inside your pocket. It should be compact in size and must have at least two USB hubs. Modern-day power banks are usually compact in size, however, if your concern is to longer charge requirement, a large size power bank will do better in terms of capacity. Usually, large-sized power banks come with high mAh power thus it will stay longer.

Multiple Ports

Again, if you are going to buy a power bank for your mobile phone, you should also check the input and output of the power bank. You should check whether the power bank has the option for Type-C, Type-B, and Micro USB ports.

With the increase in the capacity of the power banks the charging time also increases.

Types of Battery

There are two types of batteries that you get to see in the power banks. Lithium-ion(Li-ion) and Lithium-Polymer(Li-Po), there isn’t much different between the two types of battery however, Li-Po batteries are light weight than the Li-ion of the same capacity.

Other than the weight and size of the batteries with the same capacity, there is not much difference in the charging performance. Power banks with Li-Po Batteries are largely available in the market.
