Cuktech Launches $79 15 Air Power Bank With 15,000mAh Capacity and 100W Recharge

Q: Can this pocket-sized 65W charger finally make bulky laptop power bricks obsolete for travelers?

Yes—for many travelers, a compact 65W USB-C charger or power bank can replace the bulky laptop brick, but not for everyone. The Cuktech 15 Air makes the strongest case yet on the power-bank side. It delivers up to 65W from USB-C, enough for many ultrabooks and mainstream laptops that charge over USB-C Power Delivery, while also charging a phone and another accessory at the same time. Its 15,000mAh capacity in a 10.8-ounce body is unusually portable, and its 57.75Wh rating is safely within airline carry-on limits. Fast 100W recharging also makes it practical for travel days. That said, “obsolete” is too strong. A 15,000mAh pack will not replace a wall charger for long work sessions or power-hungry machines. Real-world usable capacity is typically closer to 70% to 80% of the stated rating after conversion losses, so travelers should expect roughly one meaningful laptop top-up, not all-day unlimited power. And some larger laptops, workstations, and gaming models need more than 65W to charge at full speed or while under load. Where bulky bricks are truly under pressure is from GaN chargers. Modern 65W GaN wall chargers are far smaller than traditional laptop adapters and can often charge a laptop, phone, and tablet from one compact unit. For travelers with USB-C laptops, the best setup is increasingly a small GaN wall charger plus a compact 65W power bank like the Cuktech 15 Air. So, for most USB-C laptop travelers, bulky bricks are no longer essential—just not entirely gone.

$79 buys Cuktech’s new 15 Air, a 15,000mAh power bank now on sale with 100W input charging that can refill it to 60% in 30 minutes.
10.8-ounce hardware measures 5.2 x 0.8 x 2.8 inches—smaller than many 10,000mAh rivals—using GaN transistors and silicon-carbon cells to cut size and weight.
Three ports—65W USB-C, 27W USB-C and 18W USB-A—let it charge multiple devices at once, with total simultaneous output capped at 65W and pass-through charging supported.
A color TFT display shows battery level plus port current and voltage, while the package adds a 240W USB-C cable, microfiber cloth and airline-safe labeling.
ZDNET called the model a premium but worthwhile travel option, saying its compact design and fast recharge help justify a price above cheaper 15,000mAh alternatives.
