50% Off on One of the Most Powerful GaN Chargers Available

 

The Cuktech 15 just $50.99 after applying the coupon , down from its original price of $99.99. That’s a deal worth paying attention to, especially if you’re someone who carries multiple devices and needs fast, efficient charging.

In terms of design, the Cuktech 15 builds upon the foundation of its predecessor. It’s slightly larger than the Cuktech 10, but that’s expected given the increase in power and the addition of a fourth port. The overall aesthetic remains true to the brand’s style — sleek, modern, and functional.

It features a light metallic finish, and the front panel includes a black plastic insert with a cyan-colored rim, textured for better grip. While I’m based in Europe, the unit I received came with a retractable US plug — not ideal for everyone, but the foldable design definitely adds to its portability. The package also includes a high-quality 240W, five-foot USB-C cable, which is always a nice touch.

The charger measures 3.11 x 2.56 x 1.26 inches and weighs around 0.737 lbs , making it reasonably compact for such a high-wattage device.

 

⚡️ Port Configuration & Performance

The Cuktech 15 comes with four well-spaced ports:

• Two Type-C ports capable of delivering up to 140W each when used individually (supporting PD 3.1).
• One lower-output Type-C port rated up to 33W .
• One Type-A port offering up to 18W of power.

Here’s how the power delivery works across different modes:

🔌 Single Port Mode:

• Type-C1 / C2 : Up to 140W
• Type-C3 : Up to 33W
• Type-A : Up to 18W

🔌 Multi-Port Mode:

• C1 + C2 : 100W + 33W or 65W + 65W
• C1/C2 + C3 : 100W + 33W
• C1/C2 + A : 100W + 18W
• C1 + C2 + C3 : 65W + 60W + 7.5W or 45W + 45W + 18W
• All Ports : 65W + 60W + 7.5W + 18W

This makes the Cuktech 15 versatile enough to charge two laptops simultaneously while still having enough juice left for your smartphone or other accessories.

 

📈 Power Quality & Efficiency

One important aspect often overlooked is power quality. The Cuktech 15 delivers what can be described as “clean” power, with very low ripple levels (around 25–50 mV). Lower ripple means less stress on your devices’ batteries — a big plus for long-term use.

Thanks to Gallium Nitride (GaN) technology, the charger manages to pack high wattage into a relatively small form factor without compromising efficiency. In real-world testing, I measured an average efficiency of about 80–85% at 120W load , which is excellent for a charger of this class.

While it does get warm under heavy load, it doesn’t overheat dramatically — staying within reasonable limits for a 140W power beast.
