The Hollyland 12V/2A DC2.1 Power Adapter (EU Type) is an official OEM wall-power supply assembly engineered to provide continuous, high-stability AC-to-DC current for Mars series wireless video systems and professional Wireless Intercom base stations.
While battery power is excellent for field setups, studio environments, long multi-camera broadcasts, and localized control rooms require a permanent, reliable power grid. This factory replacement adapter delivers a continuous $12\text{V}$ stream while physically locking to your hardware, protecting your multi-user communication or remote monitoring lines from accidental power cutouts.
Core Electrical & Mechanical Features
-
Threaded Mechanical Locking Collar: The 2.1mm DC barrel plug features an integrated, knurled metal screw-locking ring. This threads securely onto the outer casing of compatible Hollyland units, keeping the power plug firmly seated even if someone accidentally snags or trips over the cable on a busy set.
-
Stable 24W Power Delivery Node: Standardized to convert alternating current down to a clean, regulated $12\text{V}$ direct current output at up to $2\text{A}$. This provides plenty of overhead for complex high-frequency wireless arrays, preventing overheating or voltage dropouts during multi-hour transmission sessions.
-
Native European Type-C/E/F Compatibility: The transformer chassis houses standard round two-pin European structural prongs. It connects cleanly to universal EU wall outlets, power strips, and standard stage distribution boxes without requiring loose, dangerous travel plug adapters.
-
Integrated Inline Ferrite Core: Built with a molded ferrite choke block positioned right before the terminal plug. This core filters out high-frequency electromagnetic noise (EMI) and radio-frequency interference (RFI), preventing electrical hum from leaking into your intercom audio lines or disrupting wireless video decoding.
System Interoperability
This universal continuous mains supply interfaces directly with any center-positive $2.1\text{mm}$ threaded device requiring a 12V rail, and is explicitly matched with:

On-Set Power Sequence Best Practice: When setting up your workstation or intercom command desk, always plug the locking DC barrel connector into the back of your Hollyland base station and spin the metal locking collar until it is hand-snug before plugging the main transformer block into the live EU wall outlet. This sequence prevents small electrical arcs or power spikes from jumping across the live pins as you insert the connector, protecting the sensitive internal digital chips inside your gear.
