With smartphones, laptops, and accessories demanding more power than ever, a high-performance power bank is no longer just a luxury — it’s a necessity. Enter the Cuktech 15 Ultra, a 20,000 mAh powerhouse that promises insanely fast 165W charging, intelligent power management, and a built-in display.
Despite housing a 20,000mAh battery, the Cuktech 15 Ultra remains relatively compact. It’s not the lightest power bank on the market, but given its high power output, many will accept that trade-off. The matte-finish body feels premium and durable, resistant to fingerprints and minor scratches.
I love the 1.3-inch TFT colour display, which shows data like charge rates and battery capacity. Unlike most power banks, which leave you guessing how much charge is left, this one provides real-time power data, input/output monitoring, and temperature alerts — a genuinely useful addition.
The port selection is also impressive. The Type-C1 port delivers up to 140W, which is perfect for charging high-performance laptops. Type-C2 offers 65W output, increasing to 90W for Xiaomi devices, while the USB-A port provides a solid 33W for smaller gadgets. This versatility ensures the power bank can handle everything from smartphones to gaming laptops.
The Cuktech 15 Ultra's biggest selling point is its 165W max dual-port self-charging, which allows the power bank to recharge fully in just 45 minutes. That’s an incredible speed for a battery of this size. For users in a hurry, a quick 10-minute charge provides enough power to recharge an iPhone 15 more than once.
In terms of output, the Cuktech 15 Ultra delivers serious performance. It offers 210W total output for Xiaomi users, with the ability to charge MacBooks at 140W and a variety of other devices through its 33W UFCS support. The power distribution system is intelligently designed, ensuring efficient charging for multiple devices without excessive heat buildup. Thanks to built-in alerts and power regulation, the device manages temperature well, even under heavy loads. I’ve seen other power banks charging at high rates get too hot to handle, but that’s not the case with the 15 Ultra.
During my testing, I charged an iPhone 16 Pro from 15% to full, with 81% battery remaining in the power bank. In just 30 minutes, it took my MacBook Pro 14 M3 from 55% to 82%, leaving 61% charge still available in the power bank.
It supports a wide range of fast-charging protocols, including PPS, UFCS, QC, PD 3.1, FCP, SCP, and MiPPS. The power bank ensures fast and efficient power delivery, whether you’re charging an iPhone, Samsung, Xiaomi, MacBook, or gaming laptop.
The TFT display isn’t just an aesthetic feature — it offers real-time battery percentage, wattage tracking, input and output monitoring, and control over dual-port mode.
What’s pretty cool is that when you plug in a Xiaomi phone, the screen displays "Xiaomi 5A cable," while it shows "Samsung 5A" if charging a Samsung phone or "Apple 5A cable" when connecting an iPhone. Interestingly, when I used the cable that came with the Xiaomi 15, the charging speed was noticeably slower compared to when I used a 6A USB-C cable.
The Cuktech 15 Ultra isn’t just another power bank — it’s a true powerhouse for those who need fast, efficient, and intelligent charging. Its 165W ultra-fast charging, wide compatibility, and smart display make it one of the best high-performance portable power solutions available today.
There are a few trade-offs. The power bank is slightly bulkier than standard models, but given the speed and versatility it offers, that’s an acceptable compromise. While it works well with a wide range of devices, Xiaomi users will get the most out of it due to the 210W total output compatibility.
