A power bank can significantly extend a laptop’s battery life, but choosing the right model is not easy. Not every external battery designed for smartphones can handle charging a laptop. Below is an overview of what to look for when choosing a power bank for a laptop, followed by four models that are well suited for this task.

Below are several models that work well for charging laptops.

UGREEN PB720

Capacity is 72 watt hours, which corresponds to 20000 milliamp hours at 3.6 volts.
Charging power is up to 100 watts.
This is a compact power bank measuring 139 by 80 by 26.5 millimeters and weighing 420 grams, with a fire resistant ABS plastic корпус. It can fully charge a MacBook Air 15 or recharge an iPhone 15 Pro up to four and a half times. It supports simultaneous charging of three devices, and an LED display shows the remaining charge.

Capacity is 25000 milliamp hours, with watt hours not specified by the manufacturer.
Charging power is up to 100 watts, or up to 165 watts when charging several devices at once.
It can charge a MacBook Air with M3 processor about 1.3 times, reaching 50 percent in 33 minutes. It features a stylish design with a color screen and a size comparable to a soda can. The weight is 595 grams, which makes it less convenient for everyday carrying.

Baseus Free2Pull

Charging power is up to 76 watts.
This is a high capacity power bank designed for long trips, capable of charging laptops and smartphones many times over. Its dimensions of 235 by 115 by 22 millimeters are compact for such capacity, but the weight of 1.13 kilograms makes it less convenient for daily use. The package includes 28 adapters, including MagSafe 1 and MagSafe 2, as well as support for Power Delivery 2.0 and Quick Charge 3.0. It can charge up to three devices simultaneously.

In brief

A power bank for a laptop is an essential accessory for anyone who wants to extend laptop battery life while traveling or when away from a wall outlet. Look for models with a capacity of around 70 to 100 watt hours, charging power of at least 45 to 60 watts, and a suitable connector, preferably USB Type C with Power Delivery. Among the best options are the compact UGREEN PB720 and Baseus Free2Pull for everyday use, the stylish Anker Zolo Power Bank 25K, and the high capacity Rombica NEO PRO 450C for long journeys. Always consider weight and compatibility with your laptop to choose the ideal power bank.
