While you’re on the go or in the great outdoors with your laptop, you can keep it charged with a portable power bank. Most power banks are designed to charge smartphones, tablets, and smaller devices. A laptop is more power-hungry and will need a bigger power brick than your regular power bank.
We’ve crunched the web for the best options of charging your laptop with a power bank. But first, you must understand your laptop, specifically the wattage—which is a measure of how much power your laptop consumes. Most laptops out there will take in about 30W (e.g. the MacBook Air), 45W (e.g. Dell XPS 13), or 65W (e.g. HP Elite X2 MacBook Pro).
Laptops can be powered either via AC power (your wall socket, for example) or via Direct Current. Powerbanks mostly charge your devices directly through DC. For laptops, this requires a USB-C port on your laptop with charging capabilities.
Sadly, this is still only supported in newer high-end laptops such as MacBook Air/Pro, HP Spectre X360, Surface Pro, Dell XPS 13, etc. If your laptop has USB-C, then look out for power banks that support USB-C Power Delivery 3.0. For regular laptops that use an AC adapter, you’ll need a power bank that has an AC outlet. These are unfortunately few and a lot more expensive than those with USB-C ports.
Here are some laptops with USB-C PD support;
- MacBook Pro 13/15”/MacBook Air/MacBook 12
- DELL XPS 13 /15
- Surface Pro 7
- HP Spectre X360 / Spectre X2 / Spectre Folio / ELITE BOOK 830 G5
- Lenovo X1 / YOGA730 / E490 / ideapad 720s-13 / THINKPAD X390
- Huawei MateBook X Pro/MateBook X/MateBook13
- Samsung Notebook9(950XBE)
- Xiaomi Air
Another thing to consider is the power input or wattage of your laptop measured in watts vs the power output of the power bank. If your laptop takes in 30W and you use an 18W powerbank, it’ll either charge slowly or refuse to charge altogether. Therefore, aim for a powerbank whose power outage is either close to or more than your laptop’s rated maximum power input.
Lastly, if you plan on catching a plane, lookout for a power bank below the accepted battery rating considered for aviation. 100Wh is the standard TSA-approved figure; anything above won’t be checked in. The formulae for converting from mAh to Wh is E(Wh) = Q (mAh) × V(V) / 1000. For instance, a power bank rated 30,000mAh at 3.7 volts = 111Wh. This won’t get into the plane.
1. ROMOSS 30,000mAh Power Bank
This powerbank has three inputs (micro-USB, lightning, USB-C) and two outputs (two USB-A and USB-C). It’s able to charge up to three devices at once and can be used to charge USB-C compatible laptops through the bi-directional USB-C port. At 18W USB-C PD, it’s not the fastest way to charge your laptop.
Better to charge while not using your laptop because the rated power output is lower than 30W. Several reviewers on Amazon have reported success charging their Macbook Pro 13″ albeit at slower speeds. This power bank is $35.99 on Amazon.com. You can get a bigger 40,000mAh variant for an additional $15.

A verified buyer on Amazon was able to charge their Thinkpad 13 Chromebook and another was able to charge their Dell XPS 13 7390. You can also take this power bank with you on the plane since it’s below 100Wh TSA-approved value.
