Pros & Cons
Pros
- ✓ 6.6ft reach extends docks, MagSafe chargers, and PSVR2 gear to couch or desk-back placement
- ✓ 20Gbps data rate handles a 10GB file transfer in seconds, not minutes
- ✓ 240W (48V/5A) PD headroom covers full-speed MacBook and iPad charging
- ✓ 4K@60Hz DP Alt Mode passthrough drives a monitor or TV over the same cable
- ✓ Triple-layer shielding (foil + copper + braid) on OFC conductors for cleaner signal
Cons
- ✗ Not compatible with Thunderbolt 3 or active Thunderbolt docks
- ✗ 20Gbps and 4K@60Hz only hit spec if every device and cable in the chain supports it
- ✗ Total chain length affects speed, so stacking it with long cables degrades throughput
- ✗ Support window is 12 months, shorter than many premium cable warranties
Manufacturer description
The AINOPE USB C extension cable solves a problem you have probably worked around with a stack of adapters: your dock, MagSafe charger, or PSVR2 accessory sits three feet short of where you actually use it. At 6.6 feet, this USB-C male-to-female extension puts the port where you need it, whether that is the couch, the back of a desk, or a monitor arm. Specs are unusually strong for an extension. It carries data at up to 20Gbps, delivers 4K@60Hz video over DP Alt Mode, and passes up to 240W (48V/5A) Power Delivery, so a MacBook or iPad keeps charging at full speed instead of trickling…

Frequently Asked Questions
Will this work with a Thunderbolt 3 dock?
No. AINOPE states this extension is not compatible with Thunderbolt 3 or active Thunderbolt docks. It is built for USB-C to USB-C connections, including passive hubs, docking stations, and chargers.
Can it really charge a MacBook at full speed?
It supports up to 240W (48V/5A) USB Power Delivery, which is above what any MacBook draws. Actual charging speed still depends on your charger, the device, and any other cables in the chain.
Does it pass 4K video to a monitor?
Yes, up to 4K at 60Hz, as long as your source device, display, and the other cables all support DP Alt Mode with enough bandwidth. Triple-layer shielding is included to keep the display signal flicker-free.
How fast is data transfer?
Up to 20Gbps, which moves a 10GB file in seconds. Speed varies by device port and the other cables connected, so use USB-C to USB-C ports and keep total chain length within the recommended range.
How durable is it for daily plugging and unplugging?
AINOPE tests it to 40,000+ bends. It uses a nylon braided jacket, reinforced aluminum alloy connectors, and extended strain relief at the cable-connector joint.
