Connect the power bank to your laptop

Connect your Power Bank to your Laptop through USB Port.

This relies on the type of USB port you have on your laptop.

Look Out for the right USB Port:

A) USB Type-A:

  • Type A can exchange a sizeable amount of data but might not be suitable for high power needs.
  • But you need a large amount of power to replenish your laptop battery.
  • So, Type-A might not be apt for your Laptop.

B) USB Type-C:

  • USB-C has an oval shape, unlike Type-A.
  • It’s intended for high-wattage availability.
  • So, USB-C moves more power than USB-A moves, and also at a faster speed.
    A lot faster!

Check out your laptop’s adaptor or manual to check its USB Type-A or Type-C compatibility.

Step 4: Switch on the Power Bank

Switch on the Power Bank
  • Press the Power Button of the Power Bank to begin the charging.
  • Many Power Banks Automatically turn ON while connected.
  • This depends upon the Specs of your Power Bank.

Check the Battery Charging Status on your Laptop Screen:

  • For windows, the icon is near to a Power Plug symbol; filling up with white.
  • On a Mac, you’ll encounter a lightning bolt in the battery symbol.
