USB-C Extension Cable 3 ft

The Tripp Lite U421-003 is a male-to-female USB-C extension cable measuring 3 ft. It connects host devices to peripherals, docks or smartphones for charging and data transfer. The PVC jacket carries a VW-1 rating and uses nickel-plated connectors for durability.

Suits users needing extra reach for USB-C

This cable works with laptops, tablets and phones that have a USB-C or Thunderbolt 3 port. It does not suit buyers who require a longer cable run, a right-angle connector, or a cable rated for higher power delivery than 60 W.

5 Gbps data rate and 60 W power delivery decide fit

The cable supports USB 3.2 Gen 1 speeds up to 5 Gbps and delivers 20 V at 3 A for 60 W charging. If your device needs faster data throughput or more charging power, this cable will not meet that requirement.

Questions about this item

How much clearance does the 5.2 mm diameter cable need behind a desk or rack?

The jacket is 5.2 mm thick so allow at least that much space plus a gentle bend radius; the PVC sheath is VW-1 rated for in-wall routing.

Which end plugs into the host and which end receives the device?

Side A is a USB-C male that goes into the computer or dock; Side B is a USB-C female that accepts your existing cable or peripheral.

Will the nickel-plated contacts need cleaning or replacement over time?

Nickel resists corrosion; wipe with a dry cloth if dust builds up, otherwise no scheduled maintenance is required.
