CUKTECH 30 Ultra Review – 300W 5-Port GaN Multi-Charging Station with DC Power Output

One of the best things to happen to portable electronics has been the adoption of USB-C as a universal charging standard. You no longer need to worry about where a charger is or whether it still works, and in my case, I have USB-C chargers dotted around the house, so I can charge whatever I need in any room without hunting for the right cable.

However, most USB devices are still capped at 100W, with only a handful of laptops and other devices supporting 120W or 140W, even though USB4 and Thunderbolt 5 are capable of up to 240W charging.

For devices with higher power requirements, such as gaming laptops, you generally still need a DC barrel connector if you want to charge at full speed (these usually include a lower-powered USB port too, for topping up on the move).

Cuktech has a solution for this. Its new desktop charger supports 140W USB-C output but also has a DC port capable of 300W output. Included in the box is a DC cable with a selection of adaptors for popular laptop brands, letting you charge a gaming laptop and other devices from the same charger.

Specification

Here is the full specification sheet for the Cuktech 30 Ultra, covering the unit itself, the included cables, and the output profiles for each port.

Port Output

DC Adaptors and Compatible Models

Cuktech includes a braided DC cable along with nine conversion tips in the box, covering most of the popular gaming and creator laptop brands. Rather than one universal barrel size, each tip adapts the DC cable’s 5.5 x 2.5 mm female connector to the specific plug size and pin layout a given manufacturer uses. The table below summarises what is included. If you are relying on this for an expensive gaming laptop, it is worth double-checking the connector against Cuktech’s own compatibility chart first, since manufacturers do change barrel connectors between generations.

Looking online, an official ASUS ROG charger can cost £60-£150, and third-party replacements appear to cost between £35-£45. Third-party 240W Acer Predator chargers cost between £40-55. A single replacement laptop charger can already cost as much as a mid-range phone charger, so having nine tips bundled in as standard is a genuine cost saving if you own, or are likely to own, more than one of these laptop brands over time.

Design

The 30 Ultra is a small, dense brick of a charger. At 108 x 85 x 43.5 mm and 632 g, it is heavier than you would expect for something this size, which is generally a good sign that Cuktech has not skimped on the internal components.

The front houses the USB-A port, three USB-C ports and the display, while the DC output and IEC C5 mains input sit around the back, next to a “300W MAX” label. A single sliding Mode/Display switch runs along the top edge, used for cycling through the different display screens and DC output levels.

Cuktech supplies a magnetic, angled metal stand that tilts the unit by around 10 degrees, which makes the screen easier to read from a normal seated position, and rubberised feet keep it in place on a desk. The stand attaches magnetically rather than clipping in, and while this makes it quick to remove, it also means the unit can shift slightly when plugging and unplugging cables with any force. It is a minor gripe rather than a deal-breaker, and you can always use the charger without the stand if you would rather it sat flatter and more planted on the desk.

Display

The 1.83-inch IPS screen is the feature that sets the 30 Ultra apart from a typical GaN charger. Cuktech rates it at 850 nits peak brightness with a 170-degree viewing angle, and in practice it is bright and legible even in a well-lit room.

The first time you power it on, the charger walks you through a short on-screen tutorial explaining how the two physical buttons work. The left-hand Mode button cycles through the DC port’s output modes (USB, DC300W and DC+USB), while the right-hand Display button cycles through what the screen shows: output power, port information and temperature status. It is a sensible bit of onboarding for a device with no touchscreen, which does need a small learning curve.

Once set up, the default view shows a “TOTAL” wattage reading in the centre of the screen, with each active port highlighted in blue or yellow along the bottom. Switch to port information and you get individual voltage, current and wattage figures per port, along with the charging protocol each device has negotiated. This is more useful than it sounds. During testing, it let me confirm a device was pulling its full rated wattage from a USB-C port rather than quietly falling back to a slower profile, and separately let me see a combined 62W being drawn between two ports at once, matching what I would expect rather than something being unexpectedly throttled.

Cuktech has also included a temperature status screen, which shows how hard the internal electronics are working. This is a genuinely useful inclusion if you intend to run the charger at anything close to its rated output for extended periods, rather than just trusting the built-in protection to quietly step in if things get too hot.

The one thing missing is a touchscreen. Everything is controlled by the two physical buttons, which is fine once you know the layout, but it does mean a small amount of trial and error the first time you want to check a specific reading. A basic capacitive touch panel would make navigating between screens noticeably quicker.

Performance

On paper, the numbers are strong. The two main USB-C ports (C1 and C2) each support up to 140W via PD 3.1, which is enough to fast-charge two high-end laptops at the same time, something very few desktop chargers can manage. USB-C3 tops out at 44W, which is plenty for phones, tablets and earbuds cases, and the USB-A port covers older accessories and camera batteries at up to 22.5W.

The DC port is the headline feature, and it needs a specific mode selected before it will output any power. Pressing the Mode button steps through USB, DC300W and DC+USB, and the display confirms which mode is active. It is a sensible safety measure, since you do not want a DC barrel connector live by default, but it does catch you out the first time, since simply plugging a cable into the DC port and expecting power is not how it works. Once in DC mode, output can be limited to 100W, 140W, 180W or 240W in the settings, alongside the full 300W, which is a genuinely useful option if you are pairing the charger with a lower-powered gaming laptop and would rather not rely on the laptop’s own limiting circuitry to avoid overloading it.

I was not able to push the full 300W through the DC port myself, since I do not own a gaming laptop capable of drawing that much power, so I cannot personally vouch for sustained output at the very top end. What I can say is that the USB-C ports delivered consistent output when tested against my own 125W-capable Anker powerbank and other 100W-rated power banks, with no sign of throttling or instability, and that the unit stayed only warm rather than hot during extended multi-port use.

Multi-port behaviour is well handled too. Whether you have two, three, four or all five ports loaded at once, the printed specification and Cuktech’s own testing both show the combined output still capping out at 300W, with power shared dynamically between whatever is connected. In my own use, running a laptop off USB-C alongside a phone and a set of earbuds on the other ports at the same time did not cause any of them to charge noticeably slower than expected.

Protocol support is broad: PD 3.1 with PPS up to 100W, Xiaomi’s 120W HyperCharge, UFCS up to 44W, and the usual assortment of Quick Charge, Huawei, Samsung and Apple fast-charging standards. That covers almost any device you are likely to own, without needing to hunt down a brand-specific charger for anything short of the very newest ultra-fast phones.

Buy on Amazon

The Cuktech 30 Ultra Power Station is available on Amazon for £139, and it has not been discounted yet. The Ugreen Nexode Pro 300W Desktop Charger has an RRP of £180 but was already discounted to £160.

For comparison, Anker’s 250W Prime Charging Station carries a UK RRP of £169.99, though it is regularly discounted to around £130, and sometimes lower during sales events. It is a genuinely good charger in its own right, with a similar diagnostic display and a manual control dial, but it caps out at 250W total and has no DC output, so it cannot replace a gaming laptop’s original power brick the way the 30 Ultra can.

Ugreen’s 500W Nexode desktop charger is worth a mention too, since it is one of the only USB-C-only options with more raw wattage than the 30 Ultra. However, it spreads that power across its USB-C ports rather than offering a dedicated DC output, so anyone with a high-draw gaming laptop still needs to rely on USB-C PD, capped at 140W per port, rather than the 300W a barrel connector can provide.

I am not aware of any other desktop chargers that have a DC output for high-powered devices.

Overall

Overall, I think the Cuktech 30 Ultra Power Station is a strong desktop charger, with the 300W DC output being the main selling point, letting you charge high-powered gaming laptops without their bulky proprietary bricks.

Cuktech beat Ugreen to market with this combination of high wattage and a DC output, which deserves some credit, and as far as I am aware, there is still nothing quite like it on the market.

There are also very few 300W USB desktop chargers available at all. Ugreen is the only other big brand name at this wattage, and Anker’s 250W Prime Charging Station sits just below it. Ugreen does have the larger 500W Nexode charger, but that costs £165 and drops the DC output entirely.

While not cheap, the pricing is reasonable, undercutting the Ugreen Nexode Pro and costing only a little more than the less powerful Anker Prime Charging Station.

The bundled DC cable and laptop adaptors add real value too, something the Ugreen alternative lacks.

Ugreen’s charger is better in some regards: you get double the USB-C ports and a companion app for customising the charging behaviour, but its display is lower resolution and more basic. It also costs only around £20 more, so the difference is not dramatic.

The main niggles across my testing are the DC port’s activation flow, which is not obvious the first time you use it, and the magnetic stand, which could hold the unit a little more firmly on the desk.

Overall, I think the Cuktech 30 Ultra Power Station is a solid choice for anyone with demanding charging needs, and I am happy to recommend it.
