Anker's new powerful 26,250mAh Prime power bank brings 300W charging in travel-ready form

Anker, which is well-known for its bestselling power banks (like the Powercore 737, curr. $94.99 on Amazon), just launched its most powerful portable battery yet. The new Prime power bank (26K, 300W) is built with a 26,250 mAh capacity, and is capable of charging two laptops and a smartphone simultaneously at full speed. Two USB-C ports each support up to 140W output, while an additional USB-A port offers 22.5W. Together, the total power output can hit 300W.

First spotted in June 2025, the power bank also supports rapid recharging. With a dual 250W input, it can recharge to 40 percent in just ten minutes, or to 80 percent in 35 minutes. This level of speed should be more than apt for users who need backup power during travel or heavy workdays. Single-port charging can deliver up to 140W - great for demanding devices such as gaming laptops.

Despite its large capacity, the battery is airline-approved at 99.75Wh, just under the 100Wh limit. An integrated smart display shows charging data and device status, while app connectivity will let users adjust power output, monitor performance, and update software remotely via OTA upgrades.

Measuring 159.9 × 38 × 62.7 mm, the power bank is both compact and lightweight compared to other models of the same class. It is set to go on sale September 25 through Anker’s website, Amazon, and retail partners. Pricing will be announced closer to launch.
