How to Charge a Power Bank? You May Charge It Incorrectly!



Having a power bank with you can be extremely convenient, especially when you are out of the house and away from a power outlet. Power banks ensure that your devices won't run out of charge. However, in order to charge your devices on the go, your power bank has to be charged itself. Many of you may charge a power bank involves following ways:

1.Connect the cable to the mini-USB socket. A power bank will normally have two plug sockets: one USB socket, and one mini-USB socket. Connect the mini-USB side of the cord that came with the power bank into the power bank. The other end of the cord should be a regular USB plug. This regular USB plug will fit into either a USB wall adapter, or a USB plug on a computer. Take the mini-USB port end of the cable, and plug it into the appropriate mini-USB port on the power bank.

2.Connect the USB end of the cable to a power source. There are two ways you can connect the USB side of the power bank cable to receive energy. You can plug the USB into a USB wall adapter (like a typical iPhone charger), and then plug the adapter into a wall socket, or you can plug the USB end of the cable directly into a USB port on a laptop, desktop computer, or in a car. Whichever way you are going to connect your power bank to energy, plug in the USB end of the cable into your chosen power source.

3.Charge the power bank. Once the power bank is connected to some sort of power source, an LED light should illuminate somewhere on the power bank. This LED light indicates that the power bank is indeed receiving power and charging. When a power bank is charging successfully the light should be a yellow or orange color (however the charging color of the LED light may vary). Once the power bank is fully charged, the light may go out, or change to blue or green color. Again, this varies depending on the individual power bank. You may need to leave the power bank to charge for several hours.

4.Charge your device. Once your power bank is completely charged, it is ready to be connected to and charge a device, like a phone. Whatever charging cable you use to normally connect your phone is going to be the same cable you use to connect your phone to the power bank. The charging cable must be an adapter type charger, where it is detachable from the adapter, exposing a regular USB plug. Detach the adapter from the charging cable. Take the USB plug that was just connected to the adapter, and inset it into the power bank. Then take the other end of the cable (the end that plugs into your phone or other device), and plug it into your phone. Click on the power button of the power bank, and the power bank should instantly start charging your device.

Wait! Don’t you think it is trouble to take an Ac adapter, a USB cable or maybe another type C cable if you have a type C device and a power bank?
