The Anker PowerPort III 20W Cube Charger (A2149K11 / A2149211) promises fast charging in a compact package. But does it deliver on its claims? I’ve been using this charger for several weeks across a range of devices, and I’m ready to share my findings.

The Anker PowerPort III boasts a truly compact design. The foldaway prongs are a clever touch, making it incredibly easy to slip into a bag or pocket. Its small footprint is significantly smaller than my previous 20W charger. The build quality feels robust and premium, suggesting this charger will withstand daily use and travel.

The advertised fast-charging capabilities are largely accurate. Charging my iPhone 13 mini from 0% to 50% consistently took under 30 minutes. This is a significant improvement over my older 5W charger. I also tested it with my Samsung Galaxy S21 and an iPad Pro, and the charging speeds were impressive across the board. The charger stayed relatively cool even during extended use. Temperature control, as advertised, seems to work effectively.

However, I did notice that charging speeds were slightly slower than advertised when using a lower-quality USB-C cable. This highlights the importance of using a good quality cable with sufficient amperage to maximize charging speed. The charger itself consistently performed well, regardless of the cable used.

Pros:

• Incredibly compact and portable design.
• Fast charging speeds for various devices.
• Robust build quality.
• Effective temperature control.

Cons:

• Charging speeds slightly reduced with sub-par USB-C cables.
• Cable not included (this could be seen as a pro/con depending on your perspective)

Overall, the Anker PowerPort III 20W Cube Charger (A2149K11 / A2149211) is a fantastic little charger. Its compact design, fast charging speeds, and robust build quality make it a winner. While the charging speed can be affected by the quality of the USB-C cable used, this is a minor quibble that shouldn’t detract from its overall excellence. I highly recommend it to anyone looking for a powerful, portable fast charger.
