Overview
UGREEN 65383 is a USB4 Gen4 cable for 80Gbps data, ultra-high-resolution display and 240W charging in the 1m configuration. Its ceiling is Up to 240W USB PD 3.1 (48V/5A) for charging and Up to 80Gbps bidirectional data for data; the listed display limit is Up to single 16K@60Hz or dual 8K@60Hz; official sources also list triple 4K arrangements on suitably capable systems.
Charging ceiling
Up to 240W USB PD 3.1 (48V/5A). The charger, cable and device negotiate the final output; the lowest supported limit wins.
Data path
Up to 80Gbps bidirectional data. A USB-C connector shape does not by itself reveal the data standard.
Display path
Up to single 16K@60Hz or dual 8K@60Hz; official sources also list triple 4K arrangements on suitably capable systems. Every source, dock/adapter and display must support the requested mode.
Length and handling
1m for USB4 Gen4 cable for 80Gbps data, ultra-high-resolution display and 240W charging. Leave connector slack and avoid tight bends at the housings.
Charging explained without the guesswork
Maximum: Up to 240W USB PD 3.1 (48V/5A).
Negotiation: USB4 Gen4 and USB PD 3.1 with E-Marker; backward-compatible operation negotiates to the common capability of both endpoints.
The cable does not push maximum power into a device. USB Power Delivery negotiation lets the charger and device select a supported voltage/current combination. Battery state, temperature and system load can change the observed rate during a session.
For full rated power: use a charger port rated for at least the required wattage, avoid multi-port power sharing during the test, and confirm the device accepts that input level.
Reaching 240W requires compatible USB PD 3.1 EPR equipment across the charger, cable and receiving device.
Key features
Data ceiling
Up to 80Gbps bidirectional data. Marketing file-transfer examples are laboratory illustrations; storage and host speeds determine real results.
Video capability
Up to single 16K@60Hz or dual 8K@60Hz; official sources also list triple 4K arrangements on suitably capable systems. This requires a compatible video-capable USB-C/USB4/Thunderbolt path.
Backward compatibility
When a faster host meets a slower cable or peripheral, the link normally falls back to the common supported mode; it does not upgrade the slower device.
The USB-C shape trap
USB-C describes the connector, not a single feature set. Charging power, USB speed, DisplayPort Alt Mode and Thunderbolt certification must be checked separately.
The E-Marker identifies supported cable characteristics during USB-C power negotiation and does not override device limits.
Use scenarios
Desk charging
Use the 1m reach between a suitable USB-C charger and compatible laptop, tablet or phone.
Power-bank kit
Connect compatible USB-C power banks in the supported direction; check which power-bank port is input/output and its wattage.
File sync
Move ordinary files at up to Up to 80Gbps bidirectional data when both connected devices expose a compatible USB data mode.
Displays and docks
Use compatible USB-C/USB4/Thunderbolt hosts, docks and monitors within the Up to single 16K@60Hz or dual 8K@60Hz; official sources also list triple 4K arrangements on suitably capable systems ceiling.
Ultra-high-resolution display modes depend on host graphics, operating system, docks or adapters and display support.
Setup and usability guidance
Step 1: Check the required job before connecting: charging only, ordinary USB 2.0 sync, high-speed storage, display, dock or eGPU.
Step 2: Confirm both endpoints are USB-C and that 1m is the intended length. Similar family products can have different capabilities.
Step 3: For charging, use a suitable USB-C power adapter and a device that supports the required USB Power Delivery profile. Maximum for this cable is Up to 240W USB PD 3.1 (48V/5A).
Step 4: For data, connect directly and verify the host reports the expected class. This model is rated Up to 80Gbps bidirectional data.
Step 5: If using a display, connect directly first, select a supported resolution/refresh rate, then add any dock only after the direct path works.
Step 6: Insert straight and fully. Route a relaxed loop, keep plugs dry and disconnect by the housing rather than the cable.
Compatible devices and systems
Compatibility class: USB4 Gen4 equipment plus backward-compatible USB4, Thunderbolt 4/3 and lower USB-C modes; suited to fast SSDs, docks, high-resolution monitors, laptops, tablets and phones where their ports support the required function.
Phones and tablets
USB-C iPhone models, compatible Galaxy/Pixel phones, iPad USB-C models and Android tablets can use the functions their ports support. Lightning models need another cable.
Laptops
MacBook, Windows, Chromebook and other USB-C laptops can charge only up to the charger/device/cable common limit; data/display capability varies by port.
Handhelds and accessories
Steam Deck, Switch, power banks, cameras and controllers may charge or sync when their manuals permit USB-C-to-USB-C operation.
Docks, displays and storage
Use within the interface, speed and display limits. High-performance SSDs and monitors require matching host support.
The USB-C connector fits many device classes, but each exposes only the power, data and video functions it supports.

What this product does not do
80Gbps, 240W and 16K are independent ceilings, not simultaneous guarantees on every device; most phones and many USB-C laptops expose lower data, charging or display capability.
It does not include a charger or raise a charger/device above its own designed limit.
It does not guarantee a named charge time, file-copy time or display mode under every battery, thermal, storage and operating-system condition.
It does not repair a damaged device port, worn battery or unstable charger.
It does not prove compatibility from connector shape alone; the device and source must support the intended function.
What to do
Match SKU and length
Order SKU 65383, 1m. Similar UGREEN variants may differ in power, speed, display and LED features.
Check the full chain
Verify charger port, host port, dock/adapter, peripheral and display specifications—not just the cable headline.
Leave connector slack
Use a gentle service loop so device sockets do not carry the cable weight or repeated side force.
Test directly first
Remove hubs and adapters when diagnosing. Confirm basic charging/data/display directly, then rebuild the system one component at a time.
What not to do
Do not force a plug
Stop if a case, debris or misalignment prevents full insertion. Clean only with devices powered down.
Do not knot or crush
Do not trap the lead under chair wheels, doors or furniture, and do not wind it tightly around a charger.
Do not use when wet
Keep ports and connectors dry. Disconnect damaged, hot, corroded or discoloured equipment and have it checked.
Do not rely on a headline alone
A maximum wattage or resolution is conditional. Confirm the profile, interface and complete route.
Warnings and limitations
Heat: mild warmth can occur during high-power charging; stop use if a plug or cable becomes abnormally hot, smells burnt, arcs or shows damage.
Charging: Up to 240W USB PD 3.1 (48V/5A) is a maximum rating, not a promise that a device will request it. Multi-port chargers can lower output when other ports are used.
Data/display: Up to 80Gbps bidirectional data and Up to single 16K@60Hz or dual 8K@60Hz; official sources also list triple 4K arrangements on suitably capable systems. Real performance depends on every component.
Official regional test figures differ; regardless of the number, avoid knots, crushing and repeated sharp bending.

How to choose the right UGREEN USB-C cable
Charging only / basic sync
Choose a 480Mbps model whose wattage meets the device. 65383 is Up to 240W USB PD 3.1 (48V/5A) and Up to 80Gbps bidirectional data.
Fast SSD or dock
Choose 5Gbps, 10Gbps, 20Gbps, 40Gbps or 80Gbps only when both host and peripheral can use it.
External monitor
Choose a cable that explicitly supports video and the required resolution/refresh; many charging cables do not.
High-power laptop
Match the laptop’s requested wattage. 5A cables need compliant E-Marker electronics; 240W requires USB PD 3.1 equipment.
Up to 80Gbps requires matching USB4 Gen4 equipment; slower hosts or peripherals negotiate a lower common mode.
Troubleshooting
No charging
Check charger power, correct port, device USB-C charging support, connector seating and debris. Test without a dock or adapter.
Charging is slow
Use one charger port, verify the PD profile and watch for device heat, high workload or battery-health settings that reduce charge rate.
No data
Some charger ports are power-only. Try a known data-capable host port, confirm device mode/unlock state and test a different peripheral.
No display
Confirm the host USB-C port supports video, then test directly at a lower resolution/refresh before adding a dock.
Connection drops
Remove strain, hubs and adapters; reseat straight; update host/dock firmware; and test each component separately to find the failing link.
Unexpected warmth
Stop high-power use, inspect for damage and retry with certified compatible charger/device equipment in a ventilated area.
