Cuktech 15 Ultra review
The Cuktech 15 Ultra is a power bank with a large output designed for charging laptops and similar devices on the go. There’s no getting around the fact that it’s a sizable unit. It’s admirably thin across its width, but it’s quite long and has a thick depth. This shape may suit some but disappoint others depending on the dimensions and packing arrangements of their luggage.
Its looks aren’t anything special, adopting a two-tone grey and black color scheme that’s not the most vibrant. The front panel for the screen looks smart with its gloss finish, though, while the back panel has a subtle texture that helps with grip slightly.
The build quality of the Cuktech 15 Ultra is quite good, with materials that feel reasonably premium and there’s no flex at all when pressing any side. However, the join as the chassis meets the display is quite prominent, owing to the inset nature of the display panel, so this isn’t as seamless a design as some of the best power banks out there.
The power button is integrated within the display panel, although again there’s a fairly prominent gap around the edges. Oddly, it’s emblazoned with two vertical lines, rather than the standard power symbol, but it’s at least clear to see. It operates very smoothly, providing plenty of feedback when clicked.
The standout feature of the Cuktech 15 Ultra, though, is the screen. It can display information such as total input and output readings, as well as real-time wattage, amperage and voltage. Battery level, estimated charging times, and temperature warnings are also given.
There are also a few settings that can be adjusted using this screen: you can choose whether the first USB-C port is input only, output only, or both; and you can set the screen to always stay on – two useful features I haven’t seen on other power banks.
However, despite the full-length front panel, the actual display only comprises a small area by comparison, meaning all readouts are crammed into a relatively small space, which does compromise readability somewhat.
The Cuktech 15 Ultra features two USB-C ports and one USB-A port, delivering a total output of 165W, or a maximum of 140W from a single port. Three-way simultaneous charging is also possible, although the maximum outputs drop to 100W for one USB-C port, 45W for the other, and 15W for the USB-A port. Three ports might be plenty for some, but there are similarly sized – and even some smaller – power banks out there that manage to pack in four ports.
When it comes to performance, the Cuktech 15 Ultra managed to charge an HP Chromebook Plus 15.6-inch, which can charge at 45W, from empty to 98% in about two hours, which is an impressive performance – and it stayed cool throughout. However, it ran out of battery before it could charge the Chromebook to 100%, so it just falls short of providing even a single full charge for large devices.
Thankfully, charging the Cuktech 15 Ultra itself is quick, as it took me about an hour to top it up from 25% to full. This was via a single USB-C input, but you can use both ports at the same time for increased charging power.
Given its price, the Cuktech 15 Ultra competes with other large power banks, such as the Anker Laptop Power Bank, which is similarly priced. This bank, though, has a slightly larger capacity, and features two inbuilt USB-C for added convenience. However, its display doesn’t quite offer the same wealth of information as the Cuktech 15 Ultra. The two are closely matched, so if you went for the Cuktech 15 Ultra, you likely won’t be disappointed.
