SMUGDESK USB-C Female to DC 3.5×1.3mm PD 100W Adapter with Wattage Display

USB-C PD to 3.5×1.3 mm barrel adapter

This compact converter accepts USB-C Power Delivery input up to 100W and outputs through a centre-positive 3.5×1.3 mm DC barrel jack. It is designed for laptops and Windows tablets that charge via a 3513 port, letting users replace a bulky proprietary brick with a standard PD charger or power bank. The built-in screen cycles through real-time voltage, current and wattage readings so the charging load can be monitored at a glance.

Sustained 100W delivery

An integrated PD trigger chip automatically handshakes with PD 3.0 and QC 2.0 or 3.0 sources, negotiating the matched output voltage including 19V and 19.5V common laptop profiles. The adapter maintains the negotiated level continuously up to the 20V/5A limit rather than only in short bursts. Multi-protection circuits guard against over-voltage, over-current, short-circuit and over-temperature events during extended charging sessions.

Low-resistance contacts in a solid alloy shell

Nickel-plated USB-C female and DC barrel terminals minimise contact resistance, reducing heat build-up under continuous load. The compact alloy casing acts as a passive heatsink without any moving parts, so operation remains silent. Plug-and-play portability makes it practical for business travel or outdoor mobile power setups where a conventional laptop brick would be inconvenient.
