Cuktech is expanding its lineup of high-power GaN chargers with a new release designed for people who charge multiple devices every day. After introducing the 6 Ultra earlier this month, the company has now officially launched the Cuktech 10 Ultra, a compact 100W wall charger made for laptops, tablets, smartphones, and earbuds.
What makes the Cuktech 10 Ultra stand out right away is its four-port design. You get three USB-C ports plus one USB-A port, giving you the flexibility to power a laptop while also topping up a phone, tablet, or wireless earbuds at the same time. Even with the added port, the total output remains at a maximum of 100W, which is ideal for fast charging modern laptops and other USB-C devices.
A headline feature here is the built-in 1.57-inch smart display with touch controls. Instead of guessing whether your device is fast charging or how warm the charger is running, the screen shows key charging details like temperature status, real-time wattage, voltage, and current. Cuktech says the display reaches up to 700 nits of peak brightness and supports a wide 160-degree viewing angle, helping it stay readable in a variety of lighting and desk setups.
Power delivery is handled across four ports with clear single-port and multi-port behavior. In single-port mode, the charger can deliver up to 100W from USB-C1 or USB-C2. USB-C3 can provide up to 45W, while the USB-A port supports up to 18W. If you plug into all ports at once, the allocation shifts to 45W, 45W, 10W, and 10W respectively, helping keep everything charging safely and steadily even when multiple devices are connected.
Under the hood, the 10 Ultra uses GaN (gallium nitride) technology, which is commonly used in newer chargers to improve efficiency and thermal performance. Cuktech also includes intelligent dynamic power allocation, which is designed to distribute power optimally depending on what devices you’ve connected and how they’re charging in real time.
Thermal management is another big focus. The charger includes a temperature monitoring system that, according to Cuktech, can perform up to 36,000 checks per hour. Combined with an 8-layer safety protection system, it’s built to guard against risks like overvoltage and short circuits, aiming to deliver high power without compromising safety.
Compatibility is broad, covering popular devices including MacBooks, iPhone 17 and iPhone 16 models, the Galaxy S26 series, Pixel phones, and more—making it a practical choice if your household or workspace includes a mix of brands.
The Cuktech 10 Ultra 100W wall charger is available on Amazon for $56.99, and it also includes a 240W USB-C cable in the box at no extra cost.
