What it does well.

High-power charging with USB 2.0 data
This cable is designed for power and standard data synchronisation. It does not support monitor video, USB 3.x high-speed data or Thunderbolt functions, even when both connected USB-C devices support those features.

Key features
- Supports USB-C Power Delivery charging up to 100W with a 100W-capable source and compatible receiving device.
- An E-marker identifies the 5A-rated cable to compatible USB-C power equipment.
- USB 2.0 data support provides transfers up to 480Mbps for files, syncing and routine device connections.
- Braided nylon exterior and aluminium connector shells improve everyday abrasion resistance and handling.
- The 1-metre / 3.3-foot length balances desk reach with easy storage.

Use scenarios
Power a USB-C laptop from a compatible 65W, 90W or 100W PD charger without carrying an unnecessarily long lead.
Charge a phone, tablet, handheld console or power bank from a USB-C wall charger or USB-C PD battery.
Connect a USB-C device to a computer for USB 2.0 file transfer, backup or firmware tasks.
Use at a shared desk where one 5A-rated cable needs to serve both high-power laptops and lower-power USB-C accessories.

Setup and usability guidance
Connect one end to a USB-C charger, power bank or data-capable computer port and the other to the USB-C device.
For output above 60W, confirm the charger and device support that power level; this 5A E-marked cable then allows compatible negotiation.
Use a data-capable USB-C host port for file transfer. Some charger ports and power-bank ports provide power only.
Allow the device to negotiate power automatically; no driver or cable setting is required.
Disconnect by the aluminium housing and store in a loose coil to protect the connector strain relief.
Compatible devices and systems
- Suitable for USB-C PD laptops including compatible MacBook, Chromebook and Windows notebook models, within their accepted power profile.
- Works with USB-C tablets, phones, handheld consoles, power banks, earbuds cases and other USB-C devices; each device draws only its negotiated requirement.
- Compatible with USB-C chargers up to 100W when the charger offers the required PD profile.
- Not a Lightning cable, USB-A cable, display cable or Thunderbolt cable.
How real-world performance is decided
Advertised maximums describe what the product can support under a compatible setup; they are not a promise of constant power or speed. The connected source, cable or adapter, receiving device, active ports, software, battery state and temperature can each set a lower operating limit.
For this exact model, the practical starting point is: 100W / 20V 5A • E-marker cable • 480Mbps data • Braided 1m build. Confirm the required connector and use the verified specifications below when planning the complete signal or charging path.

Check before buying

Warnings and limitations
- One hundred watts is the cable's supported maximum; actual power is negotiated among the charger, cable and device.
- A multi-port charger may reduce output when other devices are connected.
- USB 2.0 throughput is lower than USB 3.x and real transfer speeds may be below 480Mbps.
- This model cannot carry USB-C display video, regardless of the computer's display capability.
- Stop use if a connector becomes loose, discoloured, physically damaged or abnormally hot.

Questions buyers ask.
Can this cable charge a laptop at 100W?
Yes, when the USB-C charger and laptop both support a compatible 100W PD profile. The cable supports 20V/5A and includes an E-marker; the connected equipment determines actual power.
Is it a 1-metre cable?
Yes. Exact SKU 70427 is the black 1m / 3.3ft variant in UGREEN's 100W cable family.
Does it support video to a monitor?
No. It is explicitly a charging and USB 2.0 data cable, not a DisplayPort Alt Mode or video cable.
What data speed does it support?
Up to 480Mbps under USB 2.0. Real performance depends on both USB-C ports, the device storage and the transferred files.
What does the E-marker do?
It identifies the cable's electrical capability to compatible USB-C power equipment, enabling safe negotiation of supported 5A charging profiles.
Can I use it with a 65W charger?
Yes. A 65W USB-C PD charger can use this cable; the setup will operate at the lowest compatible limit among charger, device and cable.
Will it fast-charge a phone?
It can carry compatible USB-C fast-charging power, but the phone and charger must share a supported charging protocol. The phone will not draw 100W unless designed to do so.
Is this a Thunderbolt cable?
No. It does not provide Thunderbolt, USB4 or USB 3.x performance. Choose a certified high-speed video/data cable for those tasks.
Is a wall charger included?
No. The product record is for the cable. A compatible USB-C charger is required separately for charging.
Why did charging slow when another charger port was used?
Multi-port chargers often redistribute a shared power budget when another device is connected. That behaviour comes from the charger, not a defect in this cable.
