2.1mm DC Barrel Plugs, Jacks, Panel Mount Connectors, Adapters, and Power Cables

Shop 2.1mm DC barrel connectors for low-voltage power wiring, repairs, custom cables, and device hookups. This collection includes 2.1mm DC barrel plugs, 2.1mm DC barrel jacks, panel mount jacks, inline connectors, right-angle plugs, solder-type connectors, solderless screw terminal versions, barrel adapters, extension cables, and prewired power leads. These parts are commonly used anywhere a 5.5mm x 2.1mm DC power connector is needed for dependable DC power connections.

5.5mm x 2.1mm DC Power Connectors for Repairs, Power Distribution, and Custom Wiring

5.5 x 2.1mm DC barrel plugs and jacks are widely used for low-voltage electronics, CCTV equipment, LED lighting, small devices, bench power setups, and general DC power distribution. Inline plugs and jacks are useful for replacing damaged ends or building custom leads, while panel mount DC jacks are a better fit for enclosures, projects, and permanent installations. This category also includes prewired cable options and extension leads for faster, cleaner power connections.

Inline, Panel Mount, Right-Angle, Solder-Type, and Screw Terminal Options

This collection is not limited to one connector style. You will find inline DC plugs and jacks for cable assembly, panel mount jacks for chassis installation, right-angle DC barrel plugs for tighter spaces, traditional solder-type connectors for secure permanent wiring, and solderless screw terminal DC connectors for quick field connections without soldering. That variety makes it easier to match the connector style to the actual job instead of forcing a workaround.

How to Choose the Right 2.1mm DC Barrel Connector

Start by confirming whether you need a plug, a jack, an adapter, or a complete cable. Then look at the connector style that best fits the installation. A straight inline plug may be fine for open access, while a right-angle plug helps where space is limited. Panel mount jacks work better when you want a clean, fixed connection point on a box or device. If you are repairing or extending an existing power lead, a 2.1mm DC extension cable or barrel adapter may be the simplest solution.

Adapters and Power Cables for 2.1mm DC Connections

Along with loose connectors, this category includes practical cable and adapter options such as 2.1mm DC extension cables, 2.1mm to 2.5mm barrel adapters, micro-USB to 2.1mm adapter cables, and USB to 2.1mm DC barrel plug power leads. These are useful when you need to adapt between connector types, extend a power run, or feed low-voltage equipment from an existing USB source.
