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.
Best-fit summary: A fixed workstation with two or three USB-C computers plus phones or accessories, where explicit port choice matters more than pocket portability.
Key features
Three-computer headroom
The documented C1+C2+C3 combination can reserve 140W, 100W and 60W respectively, subject to device and cable negotiation.
Four distinct USB-C roles
C1 is 140W; C2/C3 are 100W; C4 is 45W. The labels prevent a lower-power accessory from occupying the strongest path by accident.
Complete desk bundle
Official materials list the station, a 2m AC lead and a 1.5m 240W USB-C to USB-C cable.
Port map and connector roles
USB-C1
5V/3A, 9V/3A, 12V/3A, 15V/3A, 20V/5A or 28V/5A; up to 140W alone. Use a compatible PD 3.1 device and EPR-rated 5A cable for 28V.
USB-C2 / USB-C3
Each supports 5V/3A, 9V/3A, 12V/3A, 15V/3A or 20V/5A; up to 100W alone.
USB-C4
5V/3A, 9V/3A, 12V/3A, 15V/3A or 20V/2.25A; up to 45W alone.
USB-A
5V/3A, 9V/2A, 10V/2.25A or 12V/1.5A; up to 22.5W alone on a compatible profile.
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.
Exact power allocation
| 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. |
| Verified 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 exact occupied-port combination. |
Read this before connecting several devices: 140W is a single-port ceiling only on USB-C1; 300W is a shared system ceiling. The documented 140W + 100W + 60W result applies specifically to C1 + C2 + C3.
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
A 100W cable or a device limited to 20V cannot unlock 28V/5A 140W, even though the connectors fit.
Device-controlled draw
A phone may request 20W, 25W or 45W from a higher-rated port; unused capacity is not forced into it.
Renegotiation is normal
Adding or removing a cable can momentarily interrupt charging while the station assigns a new budget.
Compatible devices and systems
USB-C laptops
Compatible MacBook, Dell, HP, Lenovo, Surface and gaming handheld models can charge when they accept a listed USB PD profile. Use C1 for devices capable of more than 100W.
Phones and tablets
Compatible iPhone, iPad, Galaxy, Pixel and other USB-charged devices can use the lower-power ports without being forced to take the port maximum.
Accessories
USB-charged power banks, cameras, headphones, controllers and handheld consoles are suitable when their input matches a listed output.
Not universally compatible
A laptop that requires a proprietary barrel connector or unsupported voltage may not charge, even with a USB-C-shaped port elsewhere on the device.
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
Place the highest-demand PD 3.1 computer on C1, a second laptop on C2 and a 60W-class computer on C3 in the verified 300W arrangement.
Creator workstation
Charge a laptop, tablet, camera battery bank and phone from one organised desktop point.
Shared office hot desk
Label the cables by port so C1 is not accidentally consumed by a low-power accessory.
Travel between fixed locations
The detachable AC lead packs more cleanly than several wall bricks, but the station still needs a compatible mains socket and is not a battery.
Setup and usability guidance
- 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 exact 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 verified allocation information instead of adding all single-port maxima together.
- For 140W, use the included 240W cable or another verified 5A EPR cable and confirm that the laptop supports 28V USB PD 3.1.
Setup principle: Start with one device on the strongest intended output, then add lower-priority devices.
Everyday usability and care
Priority-port planning
C1 should normally serve the device with the highest verified input; C4 and USB-A are better reserved for lower-power gear.
Detachable mains lead
The 2m cord helps locate the charger on a desk, but the wall-end plug still needs to fit the intended India socket securely.
Cable identification
Use short labels or consistent cable routing so users do not confuse C1 with C4.
Normal charging taper
A battery near full charge can fall far below the advertised port ceiling without indicating a fault.
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 verified 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
- 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 exact India page does not confirm the mains-cord wall-end shape or a plug adapter. Verify physical India stock before promising either.
Stop-use trigger: Disconnect immediately for arcing, smoke, burning smell, melted material, visible deformation or repeated unexplained power loss.
Troubleshooting
C1 does not reach 140W
Test C1 alone, use a 5A EPR cable and confirm that the device accepts 28V PD 3.1. Many 100W-class laptops do not.
One device slows after another is connected
The station has changed its allocation. Confirm the occupied ports and compare them with the verified sharing information.
No power
Reseat both ends of the detachable AC lead, test a secure wall socket and inspect any separately used plug adapter.
Repeated restarts
Remove all devices, reconnect one known-good cable and device at a time, and stop use if cycling continues with stable connections.
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.

Product-specific FAQ
What is the maximum charging output?
The station can provide up to 300W total. The strongest single output is USB-C1 at up to 140W with a compatible PD 3.1 device and 5A EPR cable.
How does power change with multiple devices?
The clearest documented full-output arrangement is C1+C2+C3 at 140W+100W+60W. Other combinations remain within the 300W total and should be checked against the label/manual.
Can it charge a laptop?
Yes, if the laptop accepts a listed USB PD profile. A 140W session additionally requires 28V PD 3.1 and the correct cable; many laptops top out at 60W, 65W or 100W.
Which output or charging area should I use first?
Use USB-C1 for the highest-demand compatible computer, C2/C3 for up to 100W devices, C4 for up to 45W gear and USB-A for a compatible legacy cable.
Which fast-charging standards does it support?
Yes. Official materials list PD 3.1/3.0 plus common PPS and quick-charge families. Actual mode depends on the port, device and cable.
Can this regional product be used in India?
The electrical input supports India mains voltage, but the exact listing does not identify the supplied cord’s wall plug or an India adapter. Verify the physical bundle and use only a secure rated connection.
Why can charging pause or restart?
A short pause can occur when a cable is added or removed because the station must negotiate a new shared-power arrangement.
Why can real charging speed be lower than the printed wattage?
The device may be limited by its own input, cable, battery level, temperature or an active sharing mode. Printed wattage is a ceiling.
Do any of these connectors transfer data?
No. All five USB connectors are charging outputs; they do not provide files, video, docking or network data.
What is included in the package?
The verified bundle lists the station, a 1.5m 240W USB-C cable, a 2m AC lead and documentation. No India adapter is confirmed.
How do I confirm this exact model?
Match India SKU 90903B and base hardware 90903 / CD333 before using these exact port and allocation figures.
