Detailed video review of Cuktech 15 Ultra:

Cuktech 15 Ultra has great specs and a useful display

At first glance, the Cuktech 15 Ultra stands out thanks to the presence of a color display that shows basic information about charging and the internal battery status. The TFT screen has a 1.3-inch diagonal and features six practical functions.

In addition to real-time charging statistics, you can also use the display to set the port input/output or change its sleep timer.

In real time, you’ll also see warnings about excessively high or low temperatures, and even the characteristics/compatibility of the connected cable. The power bank has a capacity of 20,000 mAh and offers three USB outputs with a total power of 165 W. The single most powerful PD 3.1 port allows charging of up to 140 W.

Despite the high capacity, the manufacturer states that the Cuktech 15 Ultra meets all standards and requirements so you can take it with you when traveling, including by plane in your carry-on luggage. Not all power banks of this size and power can do that.

The power bank itself can be charged at up to 165 W using two original Cuktech 100 W and 65 W adapters, which were introduced together with this power bank. When both adapters are connected at the same time, the so-called “Beast mode” charging is activated, which reaches a full charge in an incredible 45 minutes!

These are the output power levels on the individual charging ports if you’re charging just one device:

With two devices, the power is distributed as follows:

Of course, it also supports charging three devices at the same time with the shown power levels:

So this is a stylish, powerful, and above all versatile power bank that can charge virtually any device. The ADC 2.0 protocol is supported. It’s a relatively compact accessory that, according to the manufacturer, can be compared in size to a Coca-Cola can.

It measures 44.5 mm wide and 152 mm high. The Cuktech 15 Ultra is a safe travel companion, with protection against short circuit, reset, overcurrent, overvoltage, overcharge, and excessive discharge. It’s also worth noting that the package directly includes a seriously fast 240 W 6A USB-C cable with PD3.1 support and a 1 meter length.
