Power-Bank for laptop and smartphone – what’s the difference?
The main difference lies in the power of a portable battery, namely, in its current strength and voltage.

Laptops require much more power from portable chargers. To ensure uninterrupted power supply to the laptop. You will need a Power-Bank with an output voltage of at least. 15-20 V and its current strength should be approximately 3-5 A. There are relatively fewer similar devices on the market. And they cost much more.

Key Features of Portable Laptop Battery
In addition to voltage and current. When choosing a portable battery for a laptop. You need to pay attention to a number of other important characteristics.

In the case of Type-C, you need to carefully check the characteristics: in order to be able to charge. The portable battery must support USB 3.1 technology, and the port in the laptop must support USB Power Delivery mode.

Or find a model with different interchangeable adapters – there are also those.
Capacity of a Portable Battery

How much does a power bank for a laptop cost?
Due to the high power and high capacity, external batteries for laptops are much more expensive than for smartphones. Power Bank Price in Pakistan with a capacity of 10,000 – 15,000 mAh can still be bought inexpensively. But more advanced models with a capacity of 20,000 – 30,000 mAh will require serious costs.
