UGREEN Nexode CD333 90903B 300W 5-Port GaN Desktop Charger
Overview
UGREEN 90903B / CD333 is a five-output desktop charger with four USB-C receptacles and one USB-A receptacle. USB-C1 is the premium PD 3.1 path and can negotiate up to 140W alone at 28V/5A. USB-C2 and USB-C3 can each reach 100W alone, USB-C4 up to 45W and USB-A up to 22.5W. The station’s 300W headline is a system ceiling: the clearest documented maximum arrangement is USB-C1 + USB-C2 + USB-C3 at 140W + 100W + 60W. Real draw remains controlled by every connected device and cable.
What it does well.
Key features
Three-computer headroom.
Four distinct USB-C roles.
Complete desk bundle.
Port map and connector roles
USB-C1.
USB-C2 / USB-C3.
USB-C4.
USB-A.
Port labels matter: Only USB-C1 exposes the 28V/5A 140W mode. C2 and C3 stop at 100W, C4 at 45W and USB-A at 22.5W.
Charging protocols and speed logic
Official UGREEN material identifies USB Power Delivery 3.1/3.0 and common PPS/QC/SCP/FCP/AFC-family negotiation across the appropriate ports. A protocol name describes a negotiation capability, not a guaranteed brand charging label. The 140W mode is materially different from ordinary 100W USB-C: it needs 28V PD 3.1 support and a correctly rated 5A EPR cable.
PD 3.1 requirement.
Device-controlled draw.
Renegotiation is normal.
Compatible devices and systems
USB-C laptops.
Phones and tablets.
Accessories.
Not universally compatible.
Compatibility rule: Check the device’s accepted voltage/power, then the selected port and cable. Connector shape alone is not a charging specification.
Use scenarios
Three-laptop desk.
Creator workstation.
Shared office hot desk.
Travel between fixed locations.
Setup and usability guidance
Setup principle: Start with one device on the strongest intended output, then add lower-priority devices.
- Place the station on a stable, dry, ventilated surface with the ports and mains lead free of strain.
- Inspect the supplied mains cord and verify that its wall-end plug fits the intended socket securely. Do not promise or assume a regional adapter unless the India bundle lists one.
- Connect the detachable mains cord fully to the charger and wall supply before attaching devices.
- Start with the highest-demand laptop on the strongest documented USB-C port, using a suitable 5A cable where more than 60W is requested.
- Add other devices one at a time and use the allocation information instead of adding all single-port maxima together.
- For 140W, use the included 240W cable or another 5A EPR cable and confirm that the laptop supports 28V USB PD 3.1.
Everyday usability and care
Priority-port planning.
Detachable mains lead.
Cable identification.
Normal charging taper.
Keep the vents, port openings and mains connector dry and clear. Do not stack the station beneath another warm adapter, and avoid bending the AC lead sharply where it enters either connector.
What this product does
- Centralises several negotiated USB charging outputs around one detachable AC mains connection.
- Can power compatible laptops, tablets, phones and accessories when each device fits the relevant port profile.
- Dynamically shares a defined total power budget as connections change.
- Works as a standalone charger without software, drivers or network access.
- Provides a 300W three-USB-C arrangement for C1+C2+C3.
What this product does not do
- It is not a dock, hub, display adapter, data switch, UPS or battery backup.
- The USB ports do not carry files, video, Ethernet or peripheral data.
- It does not guarantee that every port keeps its individual maximum during multi-device use.
- It cannot exceed the charging ceiling built into the device or cable.
- It does not make every five-port combination equal to the documented C1+C2+C3 arrangement.
What to do
- Use the labelled high-power USB-C ports for computers and reserve lower-power ports for phones or accessories.
- Use 5A e-marked USB-C cables for power above 60W and an EPR-rated cable when 28V PD 3.1 is required.
- Keep the station upright or flat as intended with clear ventilation around the housing.
- Allow the charger to renegotiate after adding or removing a device.
- Disconnect the mains cord before cleaning or rearranging the station.
- Use the included 240W USB-C cable for the strongest compatible C1 session.
What not to do
- Do not put the station under papers, fabric or other heat-trapping material.
- Do not use a damaged mains lead, loose wall socket or improvised plug connection.
- Do not treat a headline total as a single-port rating or add isolated maxima together.
- Do not place liquids, conductive objects or metal debris near the ports.
- Do not disassemble or continue operation after odour, arcing, repeated shutdown or visible damage.
- Do not advertise the product-specific 30-minute test graphic as a universal charge-time guarantee.
Warnings and limitations
Stop-use trigger: Disconnect immediately for arcing, smoke, burning smell, melted material, visible deformation or repeated unexplained power loss.
- The supplied mains-cord wall plug can vary by region; confirm the India pack physically when the live listing does not specify its wall end.
- High total output produces heat. Normal warmth should remain stable; abnormal heat or cycling is a stop-use condition.
- Adding or removing a device can briefly interrupt another output while the station assigns a new power budget.
- The strongest charging mode requires compatible device electronics and the correct cable, not merely a USB-C connector.
- The station is for dry indoor environments and does not provide battery backup during an outage.
- The India page does not confirm the mains-cord wall-end shape or a plug adapter. Verify physical India stock before promising either.
Troubleshooting
C1 does not reach 140W.
One device slows after another is connected.
No power.
Repeated restarts.
Useful diagnostic: If a high-power laptop is slow, test it alone on C1 with the included 240W cable. That isolates port sharing and cable capability before treating the station as faulty.
At a glance.
- System ceiling
- 300W shared across the active outputs; it is not available from a single port.
- USB-C1 alone
- Up to 140W with PD 3.1, a compatible 28V device and suitable 5A EPR cable.
- USB-C2 or C3 alone
- Up to 100W each with a compatible device and 5A cable.
- USB-C4 alone
- Up to 45W.
- USB-A alone
- Up to 22.5W on a compatible fast-charge profile.
- C1 + C2 + C3 mode
- Up to 140W + 100W + 60W = 300W total.
- Other multi-port combinations
- Dynamically allocated within 300W. Do not assume every isolated ceiling remains available; follow the charger label/manual for the occupied-port combination.
- In the box
- Match SKU 90903B or base model 90903/CD333.
Confirm the mains-cord wall plug in the physical India package.
Reserve C1 and a 5A EPR cable for any intended 140W session.
Plan multi-device use from the allocation table, not the sum of isolated port maxima.
Official model materials list 1 × UGREEN CD333 charger, 1 × 1.5m 240W USB-C to USB-C cable, 1 × 2m detachable AC power cord and user documentation. An India plug adapter is not confirmed.
