Notebook charger specifications
First of all, we need to know the specifications of the laptop charger in order to find a power bank that meets the same requirements.
The following example shows the characteristics of a laptop charger.
We have to check the output parameters:
- Voltage: 20 V.
- Current: 5 A.
This means that this charger operates at 20V and provides a maximum current of 5A.
This charger does not specify the maximum power it can provide, but we can easily get it by multiplying the voltage by the current: 20*5 = 100W.
A power bank for charging a laptop is necessary for anyone who regularly travels with their laptop. This allows you to use your laptop without a network connection. The best power banks are lightweight, durable, and have long battery life. They should also be easy to carry around and charge quickly.

How to choose an appropriate power bank?
Are you looking for a laptop power bank but don’t know which one you need? Let’s try to figure out which power bank is best for the device you want to charge.

- Connector: Includes cable with connector compatible with laptop charging port.

- Power (W): the same or more power.
What qualities should a portable laptop charger have?
First of all, a large number of milliamp-hours (mAh) is needed to fully charge a laptop. If the battery capacity is more than 20,000 mAh, then for a typical 13-inch laptop, it will provide up to 25 hours of battery life.

Of course, you can get more than 20,000 mAh in a power bank. We’ve seen 50,000mAh batteries, but that comes at the cost of one big benefit of buying a laptop – being able to carry it around with you on the go. Size and weight are important here.
USB-C is the go-to option for reasonably fast laptop charging, as it can deliver enough voltage to do more than just power components (usually around the 20V mark). But that doesn’t mean it should *only* charge your laptop. Many options come with a variety of charging ports for phones, tablets, and other devices. The more versatile the better.
