Teased in late May 2025, the Cuktech 15 Air has finally arrived in China. This new power bank is designed to be compact, and even though it’s small, it packs a big battery. To be exact, it has a rated capacity of 15,000 mAh, which, as stated by the company, allows it to charge most smartphones nearly two times.
Innovative Battery Technology
The company emphasizes that they have managed to keep the size down by utilizing next-gen SiC battery technology. This is the same kind of battery found in some of the latest Android flagship models, recognized for its high energy density. Cuktech claims that its new budget-friendly power bank achieves an energy density of 737 Wh/L.
Impressive Charging Speeds
Along with its substantial battery capacity, the Cuktech 15 Air supports up to 100 W for fast charging. However, this maximum charging speed applies only when multiple devices are plugged into the power bank. When using a single port, the speed can reach up to 90 W. The company states that this enables the portable charger to recharge the Xiaomi 15 from 0% to 85% in just 30 minutes.
Versatile Port Options
This compact power bank is equipped with one USB Type-A and two USB Type-C ports, allowing it to charge three devices simultaneously. Among these, the C1 can provide a maximum of 90 W (100 W Anker 6-feet Flow Cord currently priced at $12.99 on Amazon), while the other two ports can deliver up to 33 W of power each.
The device supports various charging protocols, such as PD, PPS, and QC, ensuring compatibility with a wide range of gadgets. Other notable features of this fast charging power bank include support for 100 W self-charging, an integrated smart screen, and multiple safety protection mechanisms.
Cuktech has introduced the 15 Air in China with a price of CNY 269, which is approximately $37.54. Although the company has not yet disclosed when this cost-effective power bank will be available globally, Cuktech typically launches most of its products outside the Chinese market.
