For weeks, the Anker Powerbank A1286 (PowerCore 20K II) 20,000mAh power bank has been my constant companion. From long commutes to weekend camping trips, it’s been put through its paces. This review details my in-depth experience with this portable power source, covering its performance, features, and overall value.
The Anker PowerCore 20K II boasts a compelling set of features. Its 20,000mAh capacity is a significant selling point, promising multiple full charges for most smartphones. The dual-port design (one USB-A and one USB-C) allows for simultaneous charging of two devices, a definite time-saver. The advertised 15W fast charging capability is also a key feature, and in my testing, it lived up to its claim.

In real-world usage, the Anker PowerCore 20K II consistently delivered on its promises. Charging my iPhone 13 Pro Max from near-empty to full took approximately 2 hours and 15 minutes, slightly faster than what I had anticipated. Simultaneously charging my AirPods Pro while charging my phone was also successful. There was no noticeable drop in charging speeds. The 15W fast charging performed excellently, a definite improvement over slower charging speeds. The build quality feels solid and robust; it’s clearly designed to withstand the rigors of everyday use and travel.
The compact size and lightweight design made it easy to carry in my bag, without feeling like extra burden. The power bank itself didn’t get excessively hot during extended use, which is a plus. Overall performance was consistently excellent.
Pros
- High capacity (20,000mAh)
- Fast 15W charging
- Dual USB ports for simultaneous charging
- Compact and lightweight design
- Solid build quality
Cons
- Slightly heavier than some competitors in the same capacity range

The Anker PowerCore 20K II (A1286) is a fantastic portable power bank. Its high capacity, fast charging capabilities, and dual-port functionality make it an incredibly practical and convenient device. While it’s slightly heavier than some competitors, the performance and build quality justify the weight. If you’re looking for a reliable and efficient power bank to keep your devices charged on the go, I highly recommend the Anker PowerCore 20K II.
