After experiencing disappointment with lesser-known power banks in the past, I decided to give Anker a try. The results left me truly impressed. Here's what I found during my testing:
Real-World Performance: Using an FNB58 USB tester and a constant current load set to 2A at 5V nominal voltage, I measured an actual energy output of 68.67 watt-hours. This measurement was taken from 100% charge down to the unit's shutdown via the USB-A port.
Why Watt-Hours Matter: Manufacturers often advertise mAh capacity, but the real indicator of a power bank's capability is watt-hours (Wh). It's a standard unit of energy that makes it easy to compare across different devices and doesn't depend on the voltage of the cell.
Impressive Efficiency: Anker states the power bank's capacity as 74Wh. My measurements showed an efficiency of over 92%! This means it converts to approximately 18,500mAh (at a nominal cell voltage of 3.7V), which is very close to the advertised 20,000mAh capacity. The power bank even delivers a stable 5V at 3.4A, exceeding the specifications.
Highly Recommended: This Anker power bank delivers precisely as advertised and offers an excellent cost-to-performance ratio. It's not only efficient but also aesthetically pleasing. While it lacks PD and quick charging features, it's essential to manage expectations given its price point.
Pros:
Real-world performance matching specifications
Impressive conversion efficiency
Consistent and stable output
Reliable brand reputation
Competitive pricing
Cons:
Lacks PD and quick charging
In conclusion, if you're looking for a power bank that offers both performance and value, Anker should be at the top of your list. This power bank has certainly won my trust and approval. You can count on it to keep your devices powered, efficiently and reliably.
