GoKawiilToss the right laptop power bank in your bag, and you'll never need to do that panicked run to the nearest outlet again. A hefty portable charger frees you to sit anywhere with your laptop and keep it running. Power banks with USB-C ports can charge phones and headphones as well, and I’ve tested more than 100 of them over the past few years. These powerful, high-capacity portable batteries are the best ones when laptop charging is a priority. For this guide, I considered power banks that are 20,000 mAh and up, enough to charge most laptops twice.
If you want some smaller portable chargers, check out my guide to the Best Power Banks or Best Qi2 and MagSafe Power Banks, or for more power, the Best Portable Power Stations.
Best Laptop Power Bank
Power bank manufacturers have made strides in pushing up potential charging rates in their high-capacity portable chargers. EcoFlow’s Rapid Pro X is a prime example, just edging out Anker’s Prime series below. Capable of delivering 300 watts, this power bank is close to the maximum capacity allowed on flights, and can charge a couple of laptops and phones at the same time via the three USB-C ports (140W, 65W, 65W) and a retractable USB-C cable (140W). It has a wee display showing remaining power as a percentage and the charging rate for each connected device. You can also check temperature and battery health, tweak the brightness and screen timeout, and even connect to your phone via the Ecoflow app (though most folks won’t need to).
The Rapid Pro offers a laundry list of charging capabilities (PD3.1, PPS, QC3.0, AFC, Apple2.4A, BC1.2, SCP, FCP, UFCS), but its greatest feature could be its super speedy recharge rate. Charge from a single USB-C input at 140 watts, and it takes an hour or so to fill, but you can plug in both at once to hit 80 percent from dead in under half an hour. Even better, Ecoflow’s dock can charge via the pogo pins on the bottom at 320 watts, enabling you to go from zero to 80 percent in just 20 minutes. You can fully charge it while you pack a bag. The Rapid Pro X comes with the 27,650 mAh model and the charging dock. Ecoflow also offers a 20,000-mAh, 230W Rapid Pro model ($140).

Best Laptop Power Bank With a Dock
Anker introduced an innovative, high-wattage, high-capacity Prime Power Bank series a few years ago with an optional docking station for faster recharging via pogo pins on the bottom. This model is more compact and powerful than ever, offering 26,250 mAh at 300 watts across two USB-C ports and one USB-A, making it suitable for charging a couple of MacBooks and a smartphone at once. It also boasts a smart display and app control, and it comes with a 3.3-foot USB-C cable. Plug in both USB-C ports, and you can recharge at 250 watts to 80 percent from zero in 20 minutes.
