USB-C extension cable with on/off switch

The AJMRTC cable extends a USB-C connection by 3.3ft and adds a built-in toggle that powers peripherals on or off without unplugging them. It is aimed at users who want to keep a dock, drive, webcam or lamp permanently cabled but cut power for privacy or energy saving. The male-to-female design works with any Type-C host and device combination. Plug-and-play operation requires no driver installation.

Sustained 10Gbps data and 4K60 video

The cable complies with the USB 3.1 Gen1 standard and maintains up to 10Gbps throughput during long transfers to external SSDs or flash drives. Double-layer shielding limits signal loss so 4K video at 60Hz remains stable across the full length. PD charging up to 20V/5A is supported continuously, though the supplier notes the cable cannot handle high-power electrical devices. Total connected male-to-male length must not exceed 1.5m for reliable operation.

Low heat, silent, minimal draw

Passive construction means no fan noise and negligible heat during normal data, video or charging use. The reinforced strain-relief connectors reduce wear from repeated insertion cycles. When the switch is off, downstream devices draw no power, eliminating standby consumption. If a connected cable or device only supports USB 2.0 or 3.0, the link falls back to 2.0 speeds without generating extra heat.

Questions about this item

Does the built-in ON/OFF switch on this 3.3ft cable generate any heat or consume power during all-day use?

The mechanical switch only opens or closes the circuit; it draws no power and adds no measurable heat while the cable runs continuously.

What host port and device cable must I already own for this USB 3.1 Gen1 male-to-female extender to function?

You need a USB-C host port and a separate USB-C male-to-male cable no longer than 1.5m to complete the connection.

Will this extender still deliver 10Gbps data and 4K@60Hz video if I keep my older USB 3.0 or 2.0 peripherals?

The cable remains fully compatible, but speed and video fall back to the lowest standard present — 3.0 or 2.0 rates instead of 10Gbps.
