After first being unveiled at IFA 2025 last month, Anker’s most powerful portable battery is now officially available for purchase. The new Anker Prime Power Bank (26k, 300W) is a true powerhouse designed for travelers or anyone like me with multiple power-hungry devices. And to celebrate the launch, Anker is offering a solid introductory discount for the next six days, dropping the price from its $229.99 MSRP to just $184.
What makes this portable power bank special is that Anker has packed an incredible amount of power into a travel-friendly package. The 26,250mAh capacity translates to 99.75Wh, keeping it just under the TSA’s 100Wh limit for carry-on luggage.
But the real headline is the power delivery. This bank has a total output of 300W, delivered through two USB-C ports capable of 140W each, plus an additional 22.5W USB-A port. In practical terms, that’s enough juice to fast-charge two power-hungry Chromebooks and a phone all at the same time.

Just as impressively, those USB-C ports are bi-directional, allowing for a combined input of 250W. Anker claims this can take the battery from empty to 80% in just 35 minutes, which is a game-changer. You can monitor all this activity on the battery’s built-in screen or via the Anker mobile app.
Anker seriously continues to push the boundaries of what’s possible with portable power, and this new Prime Power Bank looks to be an absolute beast. If you’re interested in picking one up, be sure to grab it while the limited-time launch discount is still active!
