This is too big to carry around day-to-day, and you can’t fly with it, but if you’re going off-grid for a few days, it’s the highest-capacity portable charger you can realistically carry easily. It also has a lovely pop-up lantern with three brightness settings and a versatile array of ports. I have a separate Best Portable Power Stations guide with recommendations for anyone who needs even more power.
Other Great Laptop Power Banks
Here are a few more tried and tested power banks for laptops that might be worth considering.

Shargeek 170 Power Bank for $169: Perfect for lovers of translucent tech, this power bank has a 24,000-mAh capacity capable of charging most laptops once. It looks cool, with a smart display showing battery life as a percentage, time remaining, and the input or output in watts, and it supports Power Delivery 3.1, Quick Charge 4.0, and PPS, among other standards. While the total maximum output is 170 watts, you are limited to 140 watts from a single USB-C port.
Anker Laptop Power Bank for $120: While this power bank is an excellent all-rounder and tops my best power banks guide, the 100-watt limit means it can’t charge your laptop as quickly as my other picks. If you don’t care about speed, it’s still a solid option, but sticking with Anker, some folks will prefer the Prime above, with a 300-watt maximum output, or the 737 below, because it can send or receive 140 watts from a single USB-C port.

Anker 737 Power Bank for $110: This is a versatile and reliable 24,000-mAh-capacity power bank that supports power delivery 3.1 and can send or receive up to 140 watts to charge laptops. You can charge it from zero within an hour. It’s relatively compact, but it weighs almost 1.4 pounds. The snazzy digital display shows the remaining battery percentage and stats, including the temperature, total output, cycles, and more. It fast-charged everything I tested it with, and you can charge three devices at once without a problem.
Ugreen 145W Power Bank for $70: Surprisingly compact for a 25,000-mAh battery, this weighs 1.1 pounds and has two USB-C ports and one USB-A port. Our former pick for tablets, the Ugreen, actually offers 145 watts, one USB-C port at 100W, and the other at 45W. There’s a small LED readout on the side of the battery with the current charge state of the battery. I’d have liked to see some charging info on that screen as well, but that’s a small quibble with what’s an otherwise outstanding option if you need to keep your tablet or iPad charged up wherever you are.
