Despite the advances in technology over time, batteries have not yet been born to satisfy customers with smartphone battery backup. The need to use the phone in places where there is no charge, when traveling or traveling. The power bank has been invented to solve this problem of charging the phone from time to time. This is basically a battery pack made up of some rechargeable batteries, which can be charged in advance and then charged to the battery of the mobile from that accumulated charge. There are many types of power banks available in the market at present. But which one should you buy? In this post we will look at how to buy the right power bank.

The following points should be kept in mind to buy the right power bank.

1. Capacity, price

When buying a power bank, it is important to pay attention to its capacity or charge capacity. A power bank with a capacity of at least 10,000 mAh is required to get a good experience. However, since there is no end to the ‘good’, you can also take a 20,000 mAh (or more) power bank if you want. If the battery of your phone is 3000 mAh, then your phone can be fully charged at least 3 times by a 10 thousand mAh power bank. The price of a 20,000 mAh mobile power bank in Bangladesh is around Rs. 2,500. So adjust to your budget and needs.

2. Time required to take and give charge

Exactly how long a power bank will take to take full charge depends on its own capacity and the capacity of the charger. However, power banks on average say they take two and a half to four and a half hours. Usually, power bank charges are made with mobile phone chargers. Mobile chargers have an output of 5 volts and 2 amperes for output. With such a charger, take at least 4.5 hours to charge the 10,000 mAh power bank. Many power banks have two output options (2A / 1A) which can promise to charge faster than a normal charger. But your expectation from the power bank does not have to be “quick charge”. Rather, it is enough to charge at normal times. If you buy a good brand power bank, you do not have to worry about charging time.

3. Size and shape

Since the function of a power bank is to be portable, it is important to consider their size and shape when purchasing them. There are many power banks that are round, which cannot be carried in the pocket. Best if you can buy a rectangular shaped power bank like phone. If necessary, you can carry it in your pocket. And the weight of the power bank is not too much. You can still look for alternatives when buying.

4. Additional features

Additional features of the power bank may include charge indicator, additional output port, torch etc. Charge indicator light / LCD display will show you how much charge is left or how much has been charged. If there is an additional output port, you can charge more than one device at a time. Also, some power banks may have solar chargers, although it takes much longer to be charged by such solar chargers.
