Cable purpose and audience
This BUCIER USB Type C cable delivers 40Gbps data transfer and 240W power delivery through a 90-degree male to straight female connector. It suits users who need high-speed charging, video output and fast file transfers between compatible laptops, tablets, phones, game consoles and external drives. The 0.39ft length keeps clutter minimal on crowded desks or in tight bags.
Build integration and freedoms
The angled male plug reduces strain on ports in confined spaces while the straight female end accepts standard USB-C cables or devices directly. Backward compatibility with Thunderbolt 4, Thunderbolt 3, USB 4.0, 3.2, 3.1, 3.0 and 2.0 means one cable works across generations of gear. An E-Mark chip negotiates 48V 5A safely so the cable handles demanding power profiles without extra adapters.
Sustained-load behaviour
Rated 40Gbps throughput supports measured read and write speeds up to 2500MB/s during extended large-file moves to external SSDs. The copper construction and 24-pin design maintain signal integrity for 8K@60Hz video streams at 7680x4320 resolution over long sessions. PD3.1, QC, PPS and DP protocol support keeps charging stable even when the host and peripheral negotiate maximum power continuously.

Questions about this item
Does the 40Gbps rating hold steady during long transfers or does it throttle?
The cable is rated for 40Gbps with an E-Marker chip and copper construction; sustained throughput will depend on the host, device and thermal limits of the connected hardware.
How warm does the 90° connector get when delivering 240W continuously?
The 48V 5A design with an E-Marker chip manages power delivery safely, but connector temperature will vary with ambient conditions and the charger's own thermal behaviour.
Which port on my laptop must support 8K@60Hz for the video feature to work?
The host needs a USB-C port with DisplayPort Alt Mode capable of 7680×4320 at 60Hz; the cable itself is backward compatible with Thunderbolt 4/3 and USB 4.0/3.2/3.1/3.0/2.0.
