Anker Prime 27,650mAh Review: The Most Powerful USB-C Power Bank

Anker’s Prime 27,650mAh power bank is the most powerful USB-C power bank you can buy. With 250W of combined output and 140W per USB-C port, it charges MacBook Pros, Dell XPS laptops, and iPads at their maximum speed. And at 99.54Wh, it sneaks just under the FAA limit for carry-on luggage.

Key Specs at a Glance

• Capacity: 27,650mAh / 99.54Wh
• Max Output: 250W combined
• USB-C Output: 140W per port (2 ports)
• USB-A Output: 22.5W
• Recharge Speed: 170W input (0-80% in ~30 min)
• Weight: 1.45 lbs

Who Is It For?

Business travelers, digital nomads, and power users who need to charge laptops and phones on the go without hunting for outlets. If you work from coffee shops, airports, or co-working spaces, this is the power bank to own.

250W Output Is No Joke

Each USB-C port delivers up to 140W independently. That’s enough to fast-charge a MacBook Pro 16-inch at full speed — something most power banks can’t do. When using both USB-C ports simultaneously, total output is still a combined 250W.

In practice, this means you can charge a laptop and a phone at full speed at the same time. No other power bank we’ve tested comes close.

The Smart Display

The built-in display shows real-time metrics: current wattage in and out, battery percentage, and estimated time to full or empty. It’s not just a gimmick — it’s genuinely useful for understanding how much charge you have left and how fast your devices are drawing power.

Real-World Charging Tests

• MacBook Pro 14” (M3): 0 to 80% in about 1 hour using one USB-C port
• MacBook Air M2: Full charge with about 30% power bank capacity remaining
• iPhone 15 Pro: 4+ full charges
• iPad Pro M2: 1.5 full charges

How Fast Does It Recharge?

With a 170W USB-C charger (not included), the Prime goes from 0 to 80% in approximately 30 minutes. A full 0-100% takes about 45 minutes. That’s faster than most phones charge themselves.

Flight-Friendly Design

At 99.54Wh, the Anker Prime sits just under the FAA’s 100Wh carry-on limit. This is by design — Anker maximized capacity right up to the regulatory threshold. You can fly with it on any airline without special approval.
