USB-C to 4.0 x 1.35mm Adapter

This cable converts a USB-C source to a 4.0 x 1.35mm barrel connector for powering compatible devices. It suits users who need to run or charge equipment with that specific jack from a modern USB-C port. The compact form factor makes it practical for travel or permanent desk use. Buyers whose hardware requires a different barrel size or a proprietary tip cannot use this adapter.

Behaviour under sustained load

The adapter passes power from the USB-C host to the barrel output without active electronics or voltage conversion. Its current handling is limited by the USB-C source and the cable's internal conductors, so sustained delivery matches the host's rated output. No thermal throttling or negotiation logic is present in the cable itself. Users should verify that their USB-C supply can meet the connected device's continuous draw.

Thermals noise and power

Passive construction means the cable generates no audible noise and adds negligible heat during normal operation. Power draw is determined entirely by the attached load and the USB-C supply, with no overhead from the adapter. The 16.5 cm length and 11 g weight keep voltage drop minimal for typical low-power applications. Excessive bending near the moulded ends should be avoided to maintain long-term reliability.

Questions about this item

Does the 16.5 cm cable get warm or draw noticeable power when a laptop runs all day?

The adapter is a passive cable with no active electronics, so it adds no measurable heat or power draw during continuous use.

What must the buyer already own — a USB-C power source and a device with a 4.0 x 1.35 mm barrel jack — for this cable to work?

You need a USB-C charger or port that supplies the voltage your device expects, plus a laptop or peripheral that accepts a 4.0 mm outer / 1.35 mm inner barrel connector.

Will the 15 cm length reach from a desk-mounted USB-C hub to a legacy ultrabook power port without strain?

At roughly 15 cm end-to-end, the cable suits side-by-side connections; if the hub and power port are farther apart you will need a longer lead or an extension.
