Cuktech 15 Air wins ZDNET award as fastest charging power bank
Charges to 100% in 54 minutes – 26 minutes to 50%.
ZDNET's latest Lab Award goes to the Cuktech 15 Air, which charged from 0% to 100% faster than nine competing power banks from Anker, Baseus, UGREEN, and others. Testing was conducted in ZDNET's Louisville lab using a HOBOware plug load logger to measure energy drawn from the wall at one-minute intervals. All units were charged with a 70W USB-C power adapter. The Cuktech 15 Air reached 50% in just 26 minutes and full charge in 54 minutes, making it the clear winner for users who need a quick recharge before heading out.
The results highlight the importance of real-world energy measurement over manufacturer specs. Product testing manager Gianmarco Chumbe noted that while input energy includes charging overhead, the consistent methodology provides a reliable comparison. The Cuktech 15 Air's performance is particularly notable for travelers and remote workers who rely on power banks for extended device use. ZDNET's data-driven approach ensures that recommendations are based on actual charging times, not just advertised wattage.
- ZDNET tested 10 power banks using a HOBOware plug load logger with a 70W USB-C adapter for consistent measurements.
