UGREEN 100W USB-C to USB-C Cable, 3m (90120)
Overview
UGREEN 90120 is a long 3 m USB-C to USB-C cable designed primarily for high-power charging. It supports up to 100 W Power Delivery at 20 V/5 A with a compatible charger and device, uses an E-marker chip for 5 A operation, and provides USB 2.0 data up to 480 Mbps. The nylon-braided jacket and aluminium connector housings suit desk, sofa and travel charging where extra reach matters. It is not a display cable.

What it does well.
High-power charging; no display video
UGREEN 90120 is a 3m charging and USB 2.0 sync cable. It does not carry DisplayPort Alt Mode video, USB 3.x, USB4 or Thunderbolt data. Reaching 100W requires a compatible PD charger, a 100W-capable receiving device and the charger's correct high-power port.
Key features
- Up to 100 W / 20 V 5 A USB Power Delivery when every connected component supports that profile.
- E-marker chip identifies the cable for compliant 5 A charging.
- 3 m reach for a laptop, tablet or phone used away from the charger.
- USB 2.0 data synchronization up to 480 Mbps.
- Nylon braid, aluminium housings and a 250D fibre core; model testing cites 10,000+ 90° bends.
- Backward-compatible with lower USB-C charging levels including 65 W, 45 W, 30 W and 20 W.
Use scenarios
Power a USB-C laptop from a charger behind a desk or beside a sofa.
Charge a tablet or phone while continuing to use it at a comfortable distance.
Carry one long cable for USB-C PD chargers and multiple compatible devices.
Sync documents or photos when USB 2.0 speed is sufficient.
Replace a short 60 W lead when a laptop and charger both support a higher 5 A profile.
Setup and usability guidance
Confirm that the USB-C charger can supply the wattage required by the device and that its chosen port supports that output.
Connect either USB-C end to the charger and the other to the device; the connector is reversible.
Check the device’s charging status. Some computers show negotiated wattage in system information or a battery utility.
For data, connect directly to a USB-C computer port and the target device; expect USB 2.0 performance.
Route the 3 m cable without tight coils, pinch points or trip hazards.
Compatible devices and systems
Works with USB-C charging devices including compatible MacBook, Dell XPS and other USB-C laptops, iPad models with USB-C, USB-C iPhone models, Samsung Galaxy, Google Pixel and other USB-C phones/tablets.
The connected device must accept USB-C charging, and the charger must supply its requested PD profile.
Data requires USB data support on both ports.
Real-world performance and planning
USB-C power is negotiated across the charger, this 5A E-marked cable and the receiving device. The lowest supported limit controls the result, so a 65W charger or 45W laptop will not become a 100W setup. Multi-port chargers can also reduce output when another device is connected and may briefly pause while redistributing power.
The three-metre length is intended for reach, but it must be routed safely. Avoid doorways, chair wheels, sharp furniture edges and tight coils under load. USB 2.0 data up to 480Mbps is suitable for normal sync tasks; choose a certified video/high-speed cable when a monitor or faster storage workflow is required.
Check before buying
Measure the full 3m route and leave slack at both USB-C connectors.
Use a USB-C PD charger and device that explicitly support the desired power profile.
Choose a 5A E-marked path for operation above 60W; this cable contains the required E-marker.
Buy a different cable for monitors, high-speed storage, USB4 or Thunderbolt.
Warnings and limitations
- 100 W is the cable capability, not guaranteed device input. Charger rating, port allocation, device profile, temperature and battery state control actual power.
- At 3 m, sensible cable routing matters; avoid tightly wound coils and mechanical strain.
- USB 2.0’s 480 Mbps theoretical ceiling is far below USB 3.x, and real transfers are slower.
- The model is specified as a USB-C 2.0 cable; video is not supported.

Questions buyers ask.
Will it really charge at 100 W?
It can carry up to 100 W when the charger port, device and charging protocol all support 20 V/5 A. Otherwise the system negotiates a lower level.
Can I connect a monitor with it?
No. This USB 2.0 charging/data cable does not support video output.
How fast is data transfer?
The listed ceiling is 480 Mbps under USB 2.0; real file transfers will be lower.
Does it include a 100 W charger?
No. A compatible USB-C PD charger is required separately.
Can it charge a phone safely?
Yes, with compliant USB-C equipment. The phone requests only the power profile it supports rather than receiving 100 W continuously.
Why is my laptop charging slowly?
Check charger wattage, the specific charger port, other occupied ports, laptop power demand, connector seating and battery temperature.
Does orientation matter?
No. Both USB-C plugs are reversible and either cable end can normally face the charger.
Is it Thunderbolt compatible for data?
It may physically connect, but it operates at USB 2.0 data speed and does not provide Thunderbolt functions.
What is the E-marker for?
It electronically identifies the cable’s supported high-current capability to compliant USB-C charging equipment.
Is 3 m suitable for travel?
Yes if the extra reach is useful, but coil it loosely and protect the connectors; it is bulkier than a short cable.
Will a 100W cable overcharge a phone?
No. Compliant USB-C devices request only supported voltage and current. The 100W figure is the cable's ceiling; actual output is the lowest compatible level shared by the charger, cable and phone.
Can the cable be left tightly coiled while charging?
Avoid tight coils, crushed loops and trapped cable during high-power use. Route the three-metre lead loosely with ventilation, keep it clear of walkways, and stop use if a connector, braid or strain relief becomes damaged or unusually hot.
This description applies to UGREEN 3m cable 90120. Match the SKU, length and 100W / USB 2.0 markings before use. The model is charging-focused and has no display capability; UGREEN India after-sales eligibility follows the listing terms.
