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.

Good for medium and large dogs not good for small dogs
Too big for dogs under 15 pounds. Treats are hard to get out of the four corners. My dog can barely pick this up. She weighs 12 pounds. She still found it interesting though trying to dig the treats out that she was unsuccessful. Even after I cut all the little triangle prongs off the four corners the treats are still stuck in there. There is a slot on the side that I can put half of a dental refill in the side and she can eventually get it out so there’s still somewhat of play and challenge received, but not that satisfied to me.

Great for aggressive chewers!
Size: Jumbo, Style: Peanut Butter
I have a very very aggressive chewer. She is a Rottweiler/Pitbull mix. Most toys she completely destroys within 2 days, sometimes 2 hours. I must praise this toy as she has had it for over 5 months and has not destroyed it! She loves chewing the ends and carries in her mouth squeaking it as she goes. I have 4 pups and they all take turns chewing when they can. I will be buying more Playology dog toys in the future. Thank you for making such a great toy!!

They are her favorites
Size: Medium (VALUE 2-Pack), Style: Beef, Size: Medium (VALUE 2-Pack), Style: Beef
We’ve had many dogs, many very destructive ones and wish I had these years ago. The hard toys get sharp edges, this toy is the best and yes is far better than the other red ones. My bulldog wants tug of war for 30 min to an hour every night. We’ve gotten tennis elbow, tendinitis, and pulled muscles holding onto this thing. She has tons of toys but 9pm and this is only option for her. We don’t get a choice. Easy to hold, well for a few min until your hand gets tired. First you one was about 3 years ago and she’s only on her third one. They last forever, easy to clean, and aren’t sharp edges. Seriously, better than any toy sold anywhere. My phone has hundred of pictures of Pickle holding this. She’s doing it right now. If you have a strong destructive dog that takes pride in destroying toys, ruin their confidence and get them this one.

Perfect Toy for Large Dogs
Size: Medium, Style: Cheddar Cheese
I don’t normally leave reviews, but this toy is stellar and is a new favorite for my dog! She is a large dog (70lbs cattle dog lab mix) and I accidentally bought a medium, but it actually is a great size for her! So far this stands up to her chewing, but I may need to update in a few weeks to speak for durability but it really does feel solid. Most toys don’t last an afternoon once she starts chewing, so this has already won in that regard. The shape is perfect as well. She can gnaw at it, squeak, play fetch, play tug. It bounces when she throws it around herself. The fact it smells like stinky cheese is just an added bonus for her. All around, a very well designed dog toy!
