The Cuktech 15 Ultra: A Power Bank with Turbo-Charged Performance
The Cuktech 15 Ultra power bank has been turning heads with its remarkable charging speed, offering a quick solution for those in need of rapid charging. When put to the test, the device doesn’t hold back, immediately delivering over 150W of power right out of the box. The results are impressive: within just three minutes, the device charges 10 percent, and in less than 10 minutes, the battery level hits 30 percent. By the 23-minute mark, users can expect to see a 70 percent charge.
Performance and Practicality
Despite its initial turbo boost, the Cuktech 15 Ultra’s charging speed experiences a noticeable decline as it approaches full capacity. At this stage, the rate drops to approximately 80W, which is still quite rapid. The decrease is partly due to the external battery’s own charge dropping to 70 percent when using a single port. Nevertheless, the entire charging process from 0 to 100 percent is completed in just 44 minutes and 30 seconds, a feat that remains impressive by any standard.
Convenience and Considerations
For users seeking a quick boost, the Cuktech 15 Ultra is a convenient choice, capable of transforming an empty battery into a full one in no time. While the charging speed is undoubtedly impressive, it’s important to consider the potential impact on the battery’s lifespan. The device does generate a slight amount of heat, a factor that might affect longevity over extended use. Although our testing period was limited, we would advise against frequent use of the “Beast mode” for this reason.
Normal Mode Efficiency
Interestingly, the power bank’s performance in normal mode is not significantly slower. During tests, when a sufficiently powerful charger was connected via USB-C1, the device still delivered a robust 130W. The 70 percent charge milestone was reached in about 27 minutes, only four minutes behind the Beast mode. The complete charging process from 0 to 100 percent in normal mode took well under an hour, offering a more balanced approach without sacrificing much speed.
