Cuktech 15 Ultra Design and Build Quality

Large But Thin Form Factor

Cuktech 15 Ultra has a long and thick design making it less compact than some alternatives. While it is admirably thin, its length and depth may make it difficult to fit into some bags. If you need a portable power bank for travel, its size might not be ideal.

Subtle but Basic Aesthetics

Gray and black two-tone color pattern of this power bank is straightforward yet uninspired. While the back panel has a modest roughness for improved grip, the front panel has a glossy finish that gives it a premium appearance. For people who want a more fashionable design, it does not, however offer a wide variety of colors.

Good Build Quality

The materials feel sturdy and premium, with no flex or weak points when pressed. However, the joint between the display and chassis is noticeable, making it slightly less seamless than some premium power banks.

Cuktech 15 Ultra Display and Controls

Detailed Power Readouts

Cuktech 15 Ultra’s digital display which offers full details, is its most important feature. This includes:

Real-time wattage, amperage and voltage
Total input and output readings
Battery level and estimated charging time
Temperature warnings

This level of information is rare in power banks, making it useful for those who like to monitor power usage closely.

Customizable Settings

Using the display you can:

Set the first USB-C port to input only, output only, or both
Keep the screen always on

These features provide added convenience not commonly found in other power banks.

Small Display Size

Although the front panel is large, the actual display screen is small. This means the readouts are crammed into a tiny space which can make them difficult to read at a glance.

Cuktech 15 Ultra Charging Performance

High Power Output

The Cuktech 15 Ultra delivers up to 165W total output, making it one of the most powerful power banks available. The port configuration includes:

USB-C Port 1 – Up to 140W output
USB-C Port 2 – Up to 100W output (when used alone)
USB-A Port – Up to 15W output

With three-way charging, power is split as follows:

USB-C 1: 100W
USB-C 2: 45W
USB-A: 15W

While some customers can prefer a power bank with four connections for greater versatility, this enables you to charge many devices at once.

Fast Laptop Charging

In testing, the Cuktech 15 Ultra charged an HP Chromebook Plus (45W) from 0% to 98% in two hours. This is an impressive speed, showing that it can quickly charge laptops. However, it ran out of battery before reaching 100%, which means it cannot provide a full charge for some large laptops.

Efficient Self-Charging

Recharging the Cuktech 15 Ultra itself is quick. Charging from 25% to full took about an hour using a single USB-C port. You can also use both ports at the same time to increase charging speed, which is a great feature for those in a hurry.
