SMUGDESK USB C Female to 3.5x1.35mm Male DC Power Adapter Cable

What this cable does

This USB-C female to DC 3.5x1.35mm male adapter cable carries negotiated USB Power Delivery power from a PD charger to devices that use a 3.5x1.35mm barrel jack. It replaces a dedicated DC power brick with a single universal USB-C PD source. The built-in trigger chip handles the PD handshake so the connected equipment receives a stable DC voltage. It is suited for users who want to power mini laptops, surveillance cameras, routers or LED strips from one compact charger.

When the swap makes sense

The cable only works with USB-C chargers that support Power Delivery negotiation; standard USB chargers without PD will not supply power. It cannot transmit data, so it does not replace a full-featured USB-C dock or hub. Buyers whose devices need a different barrel size, a higher voltage than their PD charger provides, or a power rating above the charger's capability should not use this adapter. Confirm the device voltage and wattage match the PD source before connecting.

Behaviour under continuous load

High-conductivity wire core keeps voltage drop low during extended operation, so cameras, routers or lights run steadily without the dips seen on thinner cables. The PD trigger maintains the negotiated profile as long as the charger can sustain it, preventing unexpected shutdowns during long recording or monitoring sessions. Compact construction adds no bulk to permanent installations or portable kits. No active cooling is required because the cable simply passes the negotiated DC current.
