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

Power banks provide an external source of energy, ensuring your laptop remains powered when you’re away from traditional charging sources, especially during travels or power outages.

Check the power bank’s output voltage and current. Typically, to charge a laptop, it should offer a 19V output and have sufficient mAh or Wh capacity to deliver adequate power.

Not all. Compatibility depends on the laptop’s charging requirements and the power bank’s specifications. Always check your laptop’s input requirements before connecting.

Yes, as long as the power bank’s output matches your laptop’s input requirements and it’s from a reputable brand. Ensure the power bank has safety features like overcharge and short circuit protection.

Charging time varies based on the power bank’s output and the laptop’s battery capacity. On average, it might take 2-4 hours, similar to wall chargers.
