You may be wondering if it’s even possible to charge your laptop with a power bank. In short, yes it is possible to charge your laptop using a power bank. However, don’t expect it to go from 0 to 100% full charge in a short amount of time. To choose the right power bank for charging your own laptop, you may want to consider 3 things: the power output, the battery capacity, and the ports.

Power Output
Each laptop carries with it different minimum power outputs from their respective chargers. This may vary depending on what laptop. For example, a 13-inch Macbook Pro needs at least 61W but gaming laptops like the Asus Zephyrus G14 have chargers that go up to 230W.
It is also possible to power your laptop with lower power outputs but expect it to just drain less quickly and not actually charge up. Likewise, to actually charge your laptop with less output you would want to charge when idle or turned off. In a nutshell, the lower the wattage of the power bank, the longer it will take to charge your laptop. Using a commonly seen 5V/2A output port may take even as long as 12 hours even when the laptop isn’t running.
Battery Capacity
When charging a laptop with a power bank, expect it to be bigger than your conventional power banks used for smartphones. A good laptop power bank should be able to get you either 1 or 2 charges. We would say a good minimum battery capacity for charging would be 20,000 mAh. Do also note that some power banks are enormous enough to look like mini generators. Just be sure to check whether or not the power bank you choose is both portable enough and has enough battery capacity for your needs.
Ports
Nowadays, laptops can be charged via USB-C, and similarly, most new power banks these days come with USB-C output ports. Alternatively, some larger capacity power banks come with an AC outlet or different connectors/adapters which allow you to plug your laptop’s proprietary charger in the power bank.
Other Things to Keep in Mind
- Do keep in mind that if you plan to fly, most airlines only allow you to carry power banks that do not exceed 100Wh or about 26000 mAh. It would be best to check, depending on your airline, what regulations on battery packs are imposed on your country when traveling.
- Note that using third-party charging cables can affect the charging process even if it does appear charging. Using a low-quality charging cable can result in much longer charging times. It would be best to use the cable that comes with the power bank or with your laptop.
- The more intense your laptop’s workload or if you have either larger laptops, gaming laptops, or laptops that have a beefy GPU. The more powerful your power bank is going to have to be in order for you to supply enough power for the laptop.
