The Anker Prime 27,650mAh power bank (model A1340) promises a lot: high capacity, rapid charging, and a smart app for control. But does it deliver on these promises in the real world? After weeks of testing with various devices, here’s my comprehensive review.

The Anker Prime A1340 boasts impressive features. The most notable is its 250W power delivery, enabling ultra-fast charging for compatible devices. The dual USB-C ports and a USB-A port allow for simultaneous charging of multiple devices. The accompanying app offers features like real-time charging status, device location tracking (using sound alerts), and smart charging optimization. Its compact design, despite the substantial 27,650mAh battery, is a major plus. The gold color adds a touch of style, although this is subjective.

In terms of charging speeds, the Anker Prime A1340 exceeded expectations. My MacBook Air (M2) charged significantly faster than with my previous power bank. Charging my iPhone 14 from 10% to 100% took considerably less time than with the standard wall adapter. The 250W output genuinely made a noticeable difference. However, the advertised recharge time of 39 minutes was only achieved with a compatible 142W charger; using a lower wattage charger obviously took longer. The smart app worked flawlessly; the location tracker was surprisingly useful, and the real-time monitoring was helpful for managing charge levels. The only minor issue I encountered was some slight heat generation during extended high-wattage charging, though it never felt dangerously hot.

Pros:

• Blazing-fast charging speeds thanks to 250W PD 3.1
• Compact size considering the battery capacity
• Three charging ports for multi-device charging
• Useful and well-designed smartphone app
• High-quality build and materials

Cons:

• 39-minute recharge time only achievable with a 142W charger.
• Some heat generation during intensive charging.
• Price point is relatively high compared to some competitors.

The Anker Prime 27,650mAh power bank (A1340) is a premium product that delivers on its promises. While the price might be a deterrent for some, the speed, convenience, and robust features make it a worthwhile investment for power users and frequent travelers who demand fast charging capabilities. The smart app adds considerable value, and the compact form factor is a significant advantage. I highly recommend it for anyone who needs reliable, high-speed power on the go.
