When we think about mobile accessories these days, the first thing that comes to our minds is a Power Bank. This device stores electrical energy and makes it available for use later for charging your phones and other devices that can be charged using USB cables. Given the increased number of applications and features in smartphones, the need for a battery backup is essential. Power banks have been serving the purpose well in this matter.
The capacity of the power banks available now varies from 2000mAh to 20000mAh. The longevity of a power bank may vary from manufacturer to manufacturer as well as depends on how the user is handling it.
How Does A Power Bank Work?
The power bank has a small socket for drawing power. This power can be drawn with the help of a USB cable from a source such as a computer or a laptop or from the wall socket adapter. For discharging, it uses full sized sockets whose number varies depending on the power capacity of the power bank.
After your Power Bank is fully charged, you can use it by plugging in a USB cable and connecting the power bank to your mobile phone. This will then transmit the power to your device and act as an appropriate savior.
As your device gets charged your power bank loses its charge. So you need to charge your power bank as and when it gets completely discharged and keep it ready for further use.
Things You Should Know About Power Banks
1) If your power bank is of 10000mAh, it does not mean that it will allow you to charge a 2000mAh power 5 times. There is a loss of power in the battery and not all of it can be delivered to your phone or any other device.
2) The power bank needs to be charged only when it is completely out of charge; otherwise, the battery life may tend to decrease eventually.
3) A good power bank, when handled with care, can last for 6 weeks to 1 year depending on the usage frequency and the make of the device.
4) If you are using the power bank only for traveling emergency, then make sure you charge the power bank fully at least once every month when it is not in regular use.
5) Larger power banks with more power do not always mean the best one. You need to decide which one to use on the basis of your phone capacity.
6) You should never overcharge your power bank as it might decrease the battery life. Refer to the LED indicator provided to see the percentage of charge on your power bank.
