The Nexode 300W is the charger you buy to stop thinking about chargers: it powers three laptops at once, matches its port ratings within 5% in independent testing, and ships with a 240W cable. It's heavy, its allocation is confusing, and it runs warm under extreme loads — but for a desk running everything at once, few bricks do more.
— THE VERDICT · JUDGEANY EDITORSWhat it is
Ugreen launched the Nexode 300W (model CD333) on September 5, 2023 as, in its own words, the world's first 300W 5-port GaN charger — a desktop charging station with four USB-C ports and one USB-A. This review covers that original model at a $269 launch MSRP — not the newer Nexode Pro 300W, a different 2026 product with a smart display and app that shares only the wattage in its name. The job it was built for: replace a whole power strip of laptop bricks with one brick.
Port power and protocols
The allocation matters because you have to remember it: USB-C1 delivers up to 140W with PD3.1 (28V/5A) and PPS, USB-C2 and C3 each top out at 100W, USB-C4 gives 45W, and the USB-A port manages 22.5W. The protocol list is the wide one — UFCS, PD3.1, PPS, QC5/QC4+, SCP, FCP, AFC on the USB-C side — and launch coverage attributes the GaN stages to Navitas GaNFast parts. The headline use case Ugreen documents: three laptops at once at 140/100/60W, which ZDNET verified in real-world testing.
Measured output: within 5% of the claims
TechPowerUp's hands-on measured maximum total output of 140/240/300/290/290W with one through five devices connected, concluding it always landed within 5% of the claimed figures — close enough to call the ratings honest. ZDNET's Adrian Kingsley-Hughes ran it at the full 300W indefinitely and found it stable and, via thermal camera, cool to the touch under real-device load. Gear Diary's multi-laptop review (4.8/5) verified the three-laptop split and a five-device split of 140/60/45/20W on the USB-C ports plus 22.5W on the A port. In box: a 2-meter AC cable and a 240W-rated USB-C to USB-C cable, which reviewers consistently call out as genuinely premium inclusions.
Thermals and efficiency
Under moderate load the picture is calm: Gadget Explained found temperatures effectively controlled — warm but never concerning — across an 847 g unit. Push harder and the honest notes appear. TechPowerUp found it gets quite toasty past 150W of sustained draw. MakeUseOf measured roughly 7W of conversion loss per port — about 35W total with five ports loaded — and a surface temperature near 50°C. Ugreen's answer is the Thermal Guard system, rated at 6000 temperature readings per minute, which derates output if things get too warm — designed behavior, and Gear Diary documented the intelligent derating explicitly. One protocol gap worth knowing: proprietary phone protocols fall back to slow speeds — MakeUseOf's Vivo X90 Pro drew only 17W against its 120W proprietary spec.
The 300W question, stated fairly
Here's the conflicting evidence, and it deserves space. Engineering channel ScottDotDot ran synthetic loads and found that at 250W across four ports, the unit began thermally throttling after about 45 minutes at 24°C ambient — ports shutting down to protect themselves — concluding it shouldn't be sold with a 300W rating, with about 200W sustainable, and noting the full 300W only materializes when one load uses the 28V rail. That directly conflicts with ZDNET's finding of indefinite full-300W output on real devices and TechPowerUp's within-5% measurement. The reconciliation: ScottDotDot's 45-minute continuous synthetic load is an extreme corner case, while real devices taper their draw as they charge — laptops don't pull 250W flat for an hour. The thermal derating kicking in under that load is arguably the designed safety behavior working. The full 300W is real in device charging; extreme sustained synthetic loads can trigger protective derating, and single-port 300W doesn't exist here.
Living with it
This is a desktop anchor, not a travel charger: multiple outlets measured 847–868 g (Ugreen doesn't publish an official weight), and it stays put on a desk exactly because it's heavy. The daily friction is mental, not physical — you must remember which port gives what, because the allocation is complex and there are no status LEDs, no display, and no power switch. That's the clearest line between this and the newer Nexode Pro line, which added the display and app control. Long-term hands-on from Android Central (six weeks) and iOSHacker (multi-week) both landed on the same conclusion: one of these replaces three bricks without drama.
Who it's for
The Nexode 300W is for the desk that runs everything at once: two or three laptops, a tablet, a phone, the whole stack, from one outlet and one cable run. It is not for travelers, not for anyone who wants per-port telemetry, and not a bargain at full price — but the price has rarely stayed at $269 for long. ZDNET noted roughly $100 street pricing with a $70 discount in late 2024, and deal trackers have shown it well under MSRP since. Check the live Amazon price; at its discounted street price this is the most power per dollar in the desktop class.
