Cuktech launches new affordable power bank with large SiC battery and 100 W fast charging

Teased in late May 2025, the Cuktech 15 Air is now available in China. It's a new power bank with a compact form factor, and while it's small in size, it has a large battery capacity. To be precise, the rated capacity is at 15,000 mAh, which, according to the company, makes the portable charger capable of charging most phones nearly two times.

The company highlights that it was able to keep the form factor small by using a new generation of SiC battery. It's the same battery tech that's available in some of the recently launched Android flagships, and it's known to have a high energy density. Specifically, Cuktech claims that the energy density of its new affordable power bank is 737 Wh/L.

Besides having a large battery capacity, the Cuktech 15 Air has support for up to 100 W fast charging. Of course, this max charging speed is only applicable when multiple devices are connected to the power bank. The single port speed is up to 90 W, which, according to the company, allows the portable charger to get the Xiaomi 15 from 0% to 85% in 30 minutes.

On that note, this new compact power bank features one USB Type-A and two USB Type-C ports. This port configuration allows the Cuktech 15 Air to power up three devices at the same time. Among the three, the C1 maxes out at 90 W (100 W Anker 6-feet Flow Cord curr. $12.99 on Amazon), while the other two can offer up to 33 W of power.

There's support for multiple charging protocols, including PD, PPS, and QC. This wide support means that the portable charger is compatible with a broad range of devices. Among the other highlights of this fast charging power bank is 100 W self-charge support, a built-in smart screen, and multiple protection features.

Cuktech launched the 15 Air in China with a price tag of CNY 269, around $37.54. The company has yet to announce when this affordable power bank will make a global debut, but Cuktech is known to bring most of its products outside the Chinese market.
