The launch of the CUKTECH 15 air power bank adds another option to the growing category of slim, high-capacity portable chargers aimed at people who work and travel with multiple devices. Designed around a 15,000mAh battery and a 65W USB-C output, the new model targets users who need enough power for both smartphones and lightweight laptops without carrying a bulky accessory in their bag.
CUKTECH positions the 15 air as a compact alternative to traditional high-capacity power banks. At under one inch thick and weighing 10.8 ounces, the device is closer in size and weight to many 10,000mAh units, despite offering a higher capacity. That balance between size and output is central to its appeal, particularly for commuters and frequent travellers who want something that fits easily into a laptop sleeve or backpack.
With a stated capacity of 15,000mAh, the power bank is positioned to handle a full day away from a wall outlet. CUKTECH estimates it can recharge an iPhone 17 Pro Max roughly 1.6 times or a Samsung Galaxy S25 Ultra around 2.2 times, which places it firmly in the mid-to-high capacity range for portable chargers. This makes it suitable for long travel days, conferences, or extended commutes where access to mains power is limited.
The 65W USB-C output allows the 15 air power bank to support laptops such as the MacBook Air and MacBook Pro, as well as models from Dell and Lenovo. According to the company, a MacBook Air M3 can reach about 48 percent charge in around 30 minutes, while an iPhone 17 Pro Max can reach approximately 67 percent in the same time frame. The unit can charge up to three devices at once, with intelligent power distribution delivering a combined output of up to 100W.
Internally, the power bank uses gallium nitride (GaN) components and silicon-carbon battery cells, technologies that are increasingly common in modern charging hardware. These materials are intended to improve efficiency and thermal performance, helping the device maintain stable temperatures during higher output charging sessions. A built-in thermal management system further supports consistent performance when charging multiple devices simultaneously.
One of the more practical design features is the integrated TFT colour display. This screen shows remaining battery capacity, current input and output power, and estimated recharge time, allowing users to monitor charging status at a glance. When paired with a 100W PD charger, the power bank itself can be recharged quickly, reaching roughly 23 percent capacity in about 10 minutes.
For travel, the 15 air power bank remains under the 100Wh limit required for carry-on luggage, making it airline compliant. It also carries CCC safety certification, which covers basic electrical and battery safety standards.
The CUKTECH 15 air power bank is available now through Amazon, priced at $79.99 in the United States and £69 in the UK.
