On May 25th, Xiaomi's ecological chain brand CUKTECH Cooltek released the second power bank product in its power bank product line - the power bank with a built-in cable. It is currently available for pre-sale on major e-commerce platforms at an introductory price of $129.
The new product features a built-in bidirectional fast charging cable with a 1A1C interface, supporting up to 55W MAX fast charging and 40W MAX self-charging. It has a battery capacity of 20000mAh. Equipped with self-developed ADC adaptive fast charging, it is compatible with various fast charging protocols such as Huawei SCP, Xiaomi fast charging, UFCS fusion fast charging, and PPS. Compared to the conventional 20000mAh 30W built-in cable power bank priced at around 150 yuan on the market, the Cooltek Power Block with its higher power and richer protocols is priced at only 129 yuan.
In terms of appearance, CoolTech adheres to its consistent family design, featuring highlighted brand color accents. The back is intricately carved with laser texture, offering a choice of four colors: Silver Beach White, Gulf Blue, Sunset Orange, and Nebula Gray. It comes with a bi-directional fast charging data cable that can be securely stored in a lockable manner when not in use. The battery level is displayed using LED digital tubes, accurately showing the remaining power.
In terms of charging capability, the power bank comes with a built-in cable supporting up to 55W MAX fast charging. It can support Xiaomi's full range of phones and tablets with a maximum of 55W fast charging. The Xiaomi 14 can reach 90% charge in just 30 minutes, while the Xiaomi Pad 6 Pro can reach 57% charge in the same time. Additionally, the built-in cable of the power bank features Cooltech ADC adaptive fast charging, compatible with various fast charging protocols including Huawei SCP, UFCS fusion fast charging, and PPS fast charging, providing non-Xiaomi users with a high-speed charging experience. The vivo X100 can reach 73% charge in 30 minutes, the Samsung S24 Ultra can reach 70% charge in 30 minutes, and the Huawei Mate 60 Pro can reach 48% charge in 30 minutes.
The laptop also supports up to 45W fast charging, and the MacBook Air can charge up to 42% in just 30 minutes. For frequent travelers who need to work on the go, this undoubtedly provides excellent support and assistance.
At the same time, with its huge capacity of 20,000mAh, it also provides on-the-go power support for long periods away from home. It can charge an iPhone 15 about 3.9 times, a Xiaomi 14 about 3.2 times, and even a MacBook Air approximately 1.2 times.
On the other hand, this cool-looking Kootech power block comes with a built-in cable that supports 9 layers of safety protection including overvoltage, overcurrent, and overtemperature, providing users with peace of mind at all times. Double-click the power button to enter low-current mode, which can charge low-current devices such as Bluetooth headphones, fitness trackers, and smartwatches. It also offers an extended 18-month warranty, ensuring free replacement in case of any quality issues.
Currently, the Cooltek Power Block with built-in cable is available for pre-sale on e-commerce platforms such as JD.com and Tmall, with a pre-sale price of only 129 yuan. Compared to the usual price of around 150 yuan for a conventional 30W 20000mAh power bank with a built-in cable, this can be considered breaking through the "cost-effectiveness ceiling".
