If you want to buy a power bank for your MacBook or laptop, you do not rush your purchase decision. Unlike power banks that are designed for smartphones and tablets, power banks for laptops fall under a completely different category. They are heavy duty and require you to take proper care of them. Unlike smartphone batteries, laptops have a much higher capacity on an average as they have more power-intensive hardware and bigger displays.

 • The first thing you need to keep in mind is the battery capacity. Laptop batteries usually have anything between 4-9 power cells. The total battery capacity in mAh should be mentioned on your laptop’s packaging or you can simply check it online at your manufacturer’s website. Your laptop power bank needs to be at least 30% higher in capacity than your total laptop battery capacity. This is because you have to account for efficiency. Power banks can lose anything between 10% to 30% capacity while charging a device.

 • Once you figure out the right capacity to get, you need to ensure the power bank is compatible with your laptop. The power output is visible in Ampere and it should be at least 1.5A if you want your laptop to charge fairly quickly. If you use anything of lower capacity, it will mean that your laptop will drain your battery faster than you can charge it if you keep it plugged into your power bank.

 • Finally, you need to ensure that the power bank you invest in is compatible with laptops and supports the appropriate charging cable. Not all power banks available in the market are from reputed brands and you need to ensure you do not end up buying something cheap and ineffective. It may not only damage your laptop but also pose health risks when using such products.
