Anker 321 Magnetic Battery (PowerCore 5K, A1616) Review: 5000mAh Wireless Portable Charger

The Anker 321 Magnetic Battery (PowerCore 5K, model A1616, A1616621) promises a convenient and powerful charging solution for iPhone users. This compact power bank boasts a 5000mAh battery and magnetic attachment, making it ideal for on-the-go charging. But does it live up to the hype? After several weeks of extensive testing, I’m ready to share my findings.

The Anker 321’s standout feature is undoubtedly its magnetic attachment. It seamlessly snaps onto the back of my iPhone 14 Pro Max, providing a secure and stable charge. This eliminates the hassle of fiddling with cables, especially in tight spaces or while multitasking. The compact size is another major plus – it easily slips into a pocket or bag without adding significant bulk. The inclusion of safety features, like the NTC temperature sensors, is also reassuring.

Beyond the magnetic charging, the power bank offers pass-through charging, which is quite useful. You can charge your phone while simultaneously topping up the power bank’s battery. This eliminates any downtime, a significant advantage over other portable chargers.

In real-world usage, the Anker 321 consistently delivered on its promise of extended battery life. While the advertised 19 hours of video playback might be a best-case scenario, I consistently achieved around 15-16 hours with regular use, which is still impressive. The charging speed is also quite good; it topped up my iPhone considerably faster than many other portable chargers I’ve used.

The magnetic alignment was unfailingly accurate and strong, even during daily use and movement. The small size and weight never felt cumbersome, making it truly portable.

Pros:

  • Magnetic attachment for seamless charging
  • Compact and lightweight design
  • Fast charging capabilities
  • Pass-through charging functionality
  • Robust safety features

Cons:

  • Slightly higher price compared to some non-magnetic alternatives
  • Only one USB-C port for charging the power bank itself.

The Anker 321 Magnetic Battery (PowerCore 5K) is a fantastic portable charger, particularly for iPhone users. Its magnetic attachment, compact design, and reliable performance make it a top contender in its class. While it comes at a slightly higher price point than some competitors, the convenience and peace of mind offered by its features justify the cost. I highly recommend the Anker 321 to anyone seeking a hassle-free and effective way to extend their iPhone’s battery life on the go.
