GaN Charger 50% Off: 4-Port Fast Charging Deal
Some time ago, I reviewed the Cuktech 10a powerful 100W GaN charger with three ports. It left positive impressions, and since then, it has served me as my primary charger for my phone, watch, laptop, and tablet. Recently, Cuktech offered me the opportunity to take a look at the model 15, a more powerful 140W GaN charger, this time, with four ports. Right now, this powerful charger is available with a massive discount at just $50.99 (with coupon applied).
The Cuktech 15 is the same as the Cuktech 10, just slightly bigger, more powerful, and with one extra port. It has a light metallic finish, but overall, it retains the brand’s identity and features. The four ports are well spaced out, and the black plastic insert with a cyan rim has a ribbed texture for better grips. Although I live in Europe, Cuktech sent me a US variant with a retractable plug. Okay, I guess. The ability to retract the plug makes it extra portable, which is nice. A high-power 240W five-foot cable is also included. The charger measures 3.11 x 2.56 x 1.26 inches and weighs 0.737 lbs.
The Cuktech 15 has four ports: two high-power Type-C ports, one Type-C port with a lower output, and one Type-A port. The first two Type-C ports can deliver a full 140W in single-port mode (PD 3.1 supported), which is nice—no asterisk or caveats here with combined power or something. If you need the full 140W for one device, you get it.
Ports are capable of working in the following modes:
| Single-port |
Type-C1 / C2: 140W max Type-C3: 33W max Type-A: 18W max |
|---|---|
| Multi-Port |
Type-C1 + C2: 100W + 33W or 65W + 65W Type-C1/C2 + Type-C3: 100W + 33W Type-C1/C2 + Type-A: 100W + 18W Type-C1 + Type-C2 + Type-C3: 65W + 60W + 7.5W or 45W + 45W + 18W Type-C1 + Type-C2 + Type-C3 + Type-A: 65W + 60W + 7.5W |
As you can see, the charger is pretty robust, and it can power two pretty powerful laptops at once and even have enough oomph to charge a smartphone, albeit at a lower power.
Another thing worth mentioning is that the Cuktech 15 delivers “clean” power with pretty low pulsations at about 25-50 mV. The rule of thumb is that the lower the pulsations, the better the charger is for your device’s battery health. In this area, Cuktech’s charger does not disappoint, and they deliver way better results than 100 mV, which is considered a standard for a good charger. Cuktech uses gallium nitride technology, which enables smaller, more powerful and efficient charging.
Speaking of efficiency, the charger is rated for 78% average or 64% at a 10% load. When charging at 120W, I received an average of 80-85%, which is good. Of course, when charging at peak power, it gets hot, but not too much.
The Cuktech 15 140W usually costs $99.99, which is undoubtedly not cheap. However, right now, you can get it for half the price, which is a very good deal, considering you get a high-quality charger with plenty of ports and very high power output. Like with the Cuktech 10, you cannot go wrong with this one.
