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:

  • Hollyland Mars Video Infrastructure: Mars 300, Mars 300 Pro, Mars 400, Mars 400S, Mars 400S Pro, Mars 400S Pro II, Mars 4K, and Mars M1 / M1 Enhanced wireless monitors.

  • Hollyland Wireless Intercom Series: Mars T1000 Base Station and Solidcom M1 Base Station control hubs.

  • Hollyland Cosmo Series: Cosmo C1 SDI/HDMI wireless transceiver hardware.

Technical Specifications Matrix

  • Official Component Family: OEM Production Infrastructure Mains Power Spares

  • Input Power Specification: AC 100V–240V ~ 50/60Hz (Universal Global Grid Voltage Adaptation)

  • Output Power Specification: DC 12V ⎓ 2A (24 Watts Total Continuous Capacity)

  • DC Terminal Configuration: 2.1mm Inner Diameter / Center-Positive (+) with Outer Locking Thread

  • Wall Socket Plug Adapter Geometry: European Standard 2-Pin Type Configuration

  • Color Configuration Profile: Production Matte Black with Silver Metallic Lock Accent

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.

Not suitable if you have a silicone case.
I'm waiting for delivery of new phone case, as the silicone one I have on my phone will not hold onto the magnet provided for this holder. Installation was a snap and I love how it looks in my car. Cost seems fair for the product. Fingers crossed that it will work fine once I get a new case.

Charger portion stopped working twice now
Works well until it doesn't. Was excited to get the phone mount off the car vent but I have gone through one replacement already and now I'm past the point to completely return it. Twice now the charging portion has failed. The first one stopped lighting up completely with in about a week and now this one just constantly flashes and no longer charges after another few weeks. I have tried different cords and outlets in my car with no success. The magnet portion however is strong and does hold the phone well.

Perfect for every day use
The Wincar Magnetic Wireless Phone Mount and Charger is a thoughtfully designed accessory tailored for Toyota 4Runner models from 2010 to the present, and it also fits well with other vehicles using a 17mm ball mount base. The package includes a sturdy mount, a 15W magnetic wireless charger, a charging cable, and two steel rings. These steel rings are particularly useful for those who do not own a MagSafe-compatible phone or case, ensuring broader compatibility.  I specifically purchased this charger and holder to use with my existing 17mm ball mount base, which I found challenging to match with most other products—especially for my Lexus GX460. While there are many phone holders on the market, very few offer the dual functionality of both MagSafe mounting and wireless charging in one unit. This all-in-one solution eliminates the need for multiple accessories, but it’s important to note that the charger /mount  require a power connection to operate.  In terms of performance, the Wincar mount and charger deliver impressively. When connected to a reliable USB-C charging source or a USB-C cigarette lighter adapter, the magnetic grip is strong, keeping the phone securely in place even during bumpy rides. The wireless charging is efficient, providing a reasonably fast charge without overheating or lag. The magnetic force is particularly robust, ensuring that the phone remains stable and aligned for optimal charging.  Overall, this mount and charger combination offers a seamless, convenient experience for anyone seeking a reliable phone holder and charger for their vehicle. For my needs, it has proven to be both practical and effective.

A Solid Mount with Minor Imperfections
This MagSafe mount is a fantastic addition to my 2024 4Runner, offering a nearly factory-fit look. Installation was straightforward, though it required a bit of nerve. I was worried the clips attaching to the AC vent would snap, but with firm, steady pressure, they clicked securely into place without any issue. The result is a very stable platform for my phone. Functionally, it performs exactly as hoped. It supports fast charging when paired with a capable cigarette port adapter, and the magnetic connection is surprisingly strong. It holds my heavy S25 Ultra securely during daily commutes, and the inclusion of two metal rings for non-MagSafe cases is a thoughtful touch. I haven't tested its limits on a bumpy off-road trail, but for normal driving, it’s perfect. My only two critiques are minor but worth noting. With the phone in place, it completely blocks the hazard light button. A slight inconvenience. Additionally, I wish the mount's color matched the silver trim around the infotainment system for a more seamless look. Despite these small flaws, it's an excellent, clean mounting solution that I would recommend to other 4Runner owners.
