Avoid these 4 mistakes while buying a power bank.

Not only on long journey but today we also keep the power bank at the office, because the battery of the phone will end soon due to excessive use of the phone in the present time.  

There are also some apps in Android phones, which are used to spend more on batteries. In this case, there is a need for a power bank.  

Do not buy power bank by looking at battery capacity, size and color, but there are some other things that need to be kept in mind.

Power Bank of 2.5 times more capacity
 
Buy Power Bank for Phone Charging, then be sure that the power bank's capacity is 2.5 times the battery capacity of your smartphone.  

This will charge the phone faster. Plus, the power bank's battery will also last longer and you can charge your smartphone multiple times. 

With this, whenever you take a power bank, how many MAH batteries it has.


Usb charging
 
Also monitor the power bank's USB charging. 

When purchasing powerbank, check the battery charging along with battery capacity as the old power bank in the market only works with its USB cable. 

In this way, you will have a lot of trouble charging your Android phone with the power bank. Such a power bank will not be of any use to your phone.

Take power bank based on the number of devices
 
Nowadays, most working people have more than one smartphone.  

With the problem of charging, both phones should not be closed. Buy more power bank for this. 

 But if you have the same device, then a low capacity power bank can also take it.

Output voltage
 Use Power Bank, then be sure to check the output voltage of the power bank. 

 If the output voltage of your power bank is not equal to the output voltage of your phone, then the phone will not be charged. 

 In this case, keep in mind that the output voltage of the power bank should always be equal to the output voltage of your phone charger.  

Even if the output voltage is not equal, you will not be able to charge the power bank with your phone charger.
