Cuktech has announced the 15 Ultra 20,000 mAh power bank, which is now on sale in the US and UK. The new power bank offers three ports, with a maximum of 140 W or triple port output of 210 W. It also comes with a smart TFT color display and supports a wide range of fast charging protocols. 

China-based charging solutions manufacturer Cuktech has launched its latest 15 Ultra power bank with a large 20,000 mAh capacity. The accessory is designed to power various laptops, smartphones, tablets, and gaming handhelds. The 15 Ultra has three ports, including two USB-C ports and one USB-A, with a total output of 210 W. 

As far as the power allocation is concerned, the USB-C1 port can offer up to 140 W, the USB-C2 up to 65 W (90 W for Xiaomi devices), and up to 33 W via USB-A when used individually. With all three ports in use, the USB-C1 provides 100 W, while the other two outputs offer 45 W and 15 W charging speeds, respectively. It can be fully charged at 165 W via USB-C dual-port self-charging in just 45 minutes.

Dimensionally, the portable powerhouse measures 5.98 x 2.25 x 1.75 inches (151.8 x 57.1 x 44.4 mm) and weighs around 589 grams (~1.3 lbs). According to Cuktech, this would allow you to charge smartphones to 70% in just 20 minutes. It also supports a wide range of fast-charging protocols, including PPS, UFSC, QC, PD 3.1, FCP, SCP, and MiPPS. Unlike other power bank makers such as Ugreen, Cuktech also ships a 3.2 ft (0.97 m) PD 3.1 cable in the box, which is super convenient. 

The 15 Ultra has a 1.3-inch color TFT smart display that showcases various information such as real-time charging data, customizable settings, temperature alerts, connected device interface, and screen always-on control. It also offers controls for dual-port mode. 

In the US and UK, the Cuktech 15 Ultra 20,000 mAh power bank is currently selling via Amazon for $119.99/£89.95, respectively. It comes in a sole gray color option. For more details, head over to the Cuktech 15 Ultra official product page.
