Anker PowerCore 20100mAh (A1271) Review: Ultra High Capacity Portable Charger
For weeks, the Anker PowerCore 20100mAh (A1271) has been my constant companion. I’ve put it through the paces, from powering my iPhone during long days out to keeping my iPad topped up on trips. This review details my experiences with this ultra high-capacity portable charger, weighing in at a surprisingly light 12.5 ounces (356g).
The Anker PowerCore 20100 boasts several key features. Its dual USB ports allow for simultaneous charging, a significant time saver. The PowerIQ and VoltageBoost technologies promise fast charging, though it’s important to note the absence of Qualcomm Quick Charge support. The inclusion of indicator lights provides a clear visual representation of the remaining battery life, eliminating the guesswork. The build quality feels solid and premium, and the inclusion of a travel pouch is a thoughtful touch.

In real-world testing, the Anker PowerCore 20100mAh consistently lived up to its claims. Charging my iPhone 8 multiple times on a single charge was easily achievable. The charging speed, while not lightning fast, was noticeably quicker than with other comparable power banks I’ve used. The dual-port functionality proved exceptionally useful when charging both my phone and headphones simultaneously. The battery indicator lights were accurate and helpful in gauging remaining power. I did notice a slight warm-up during extended charging sessions, but nothing excessive or concerning.
I also tested the power bank with my iPad Mini 4 and Samsung Galaxy S8 and the charging performance was great across all devices. Anker’s claim of multiple full charges matched my experience. The device is surprisingly light given its capacity, and it’s certainly portable enough for everyday carry. The size is comparable to a larger smartphone, making it unobtrusive in a bag or pocket.
Pros:
- High capacity – charges multiple devices fully.
- Fast charging speeds thanks to PowerIQ and VoltageBoost.
- Dual USB ports for simultaneous charging.
- Lightweight and portable design.
- Accurate battery indicator lights.
- Solid build quality.
Cons:
- Lacks Qualcomm Quick Charge support.
- Can get slightly warm during extended use.
- Micro USB input port is becoming less common.
Overall, the Anker PowerCore 20100mAh (A1271) is a fantastic portable charger. Its high capacity, fast charging capabilities, and dual-port functionality make it ideal for frequent travelers or anyone who needs reliable power on the go. While the lack of Quick Charge support and the slight warmth during extended use are minor drawbacks, they are easily outweighed by its numerous strengths. I highly recommend this power bank to anyone seeking a reliable and efficient solution for their portable charging needs.
