Cuktech's Latest Power Bank Packs 15,000mAh Into Ultra-Compact Design Using Silicon Carbide Technology
Chinese electronics manufacturer Cuktech has officially launched its 15 Air power bank in the domestic market, introducing what the company claims is a breakthrough in portable charging technology. The device leverages silicon carbide (SiC) battery technology to achieve a 15,000mAh capacity while maintaining an unusually compact form factor.
The standout feature of the Cuktech 15 Air lies in its use of silicon carbide battery cells, the same advanced technology found in recent flagship Android smartphones. This newer battery chemistry offers significantly higher energy density compared to traditional lithium-ion alternatives. According to Cuktech's specifications, the power bank achieves an energy density of 737 Wh/L, allowing the company to pack substantial charging capacity into a device small enough for everyday carry.
The Cuktech 15 Air demonstrates how silicon carbide technology enables high-capacity batteries in compact designs
Beyond its impressive battery capacity, the 15 Air delivers substantial charging speeds through its multi-port configuration. The device features two USB Type-C ports and one USB Type-A port, enabling simultaneous charging of up to three devices. When used individually, the primary USB-C port can deliver up to 90W of power, while the combined output across all ports reaches 100W maximum.
Cuktech demonstrates the practical implications of this charging speed by citing real-world performance with popular devices. The company claims the power bank can charge a Xiaomi 15 smartphone from 0% to 85% in just 30 minutes when connected to the high-power USB-C port. For most smartphones, the 15,000mAh capacity provides nearly two complete charging cycles, according to the manufacturer.
The power bank supports multiple charging protocols including Power Delivery (PD), Programmable Power Supply (PPS), and Quick Charge (QC), ensuring compatibility with a wide range of devices from smartphones to laptops. This broad protocol support addresses one of the common frustrations with portable chargers, where devices may charge slowly or not at all due to incompatible charging standards.
Additional features include 100W self-charging capability, allowing the power bank itself to recharge quickly when connected to an appropriate charger. The device also incorporates a built-in smart screen for monitoring charging status and includes multiple protection features to safeguard connected devices from overcharging, overheating, and power surges.
Market Position and Availability
Cuktech has positioned the 15 Air as an affordable option in the high-capacity power bank market, launching it in China with a price of CNY 269, approximately $37.54. This pricing strategy places the device significantly below many competing products with similar specifications, potentially making advanced silicon carbide battery technology accessible to a broader consumer base.
The company has not yet announced international availability for the 15 Air, though Cuktech historically brings most of its products to global markets following their Chinese debuts. The power bank represents part of a broader industry trend toward adopting silicon carbide technology in consumer electronics, driven by the material's superior energy density and thermal properties compared to traditional battery chemistries.
For consumers seeking portable charging solutions, the Cuktech 15 Air addresses the persistent challenge of balancing capacity, size, and charging speed. While the long-term reliability of silicon carbide batteries in consumer applications remains to be proven at scale, the technology's adoption in flagship smartphones suggests growing confidence in its commercial viability.
