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.

My raptor GSP destroyed this dino toy
Color: Medium - Dilophosaurus, Color: Medium - Dilophosaurus
My dog ripped this toy apart faster than the trex did the lawyer in Jurassic Park. 2 hours! Arm was ripped off, stuffing pulled out methodically over the next to days. Now it is a gutless husk. The metor was kinder to the og dinos than my gsp was to this. Sorry Bite Force. Open to product sampling tho!

My Hero pup is super happy with it
Color: Large - Billy the Beast Monster
I was super excited to order this and had waited some time to do so. I wanted Big Billy The Beast Monster in large Green, he’s an awesome looking guy. My Golden Retriever was all over me while I was up packaging Him and his tail was in helicopter mode. He was so excited to have it and carried it around the house everywhere we went, he’s laying on me with his head in my lap and Billy’s right next to him. Reason for buying it? Well he loves plushies but there are not many available out there that can stand up to this 80 pound chew monster so I have to keep him on harder stuff, 2 of which are the cheapest toy skull and crosses in orange and blue from a cheap outlet site but he loves them. Orange was first then when we pulled out the blue one he had a aha moment. Now with Billy he was on a whole new level of excitement, I’ve never seen him this excited over a toy, he can’t stop carrying it with him everywhere and showing it off to the other pups I have, there’s no growling or resource guarding but he definitely won’t want to share and that’s of because I always take away any plushies that he gets to because he is serious about chewing. This being made with Kevlar gave me hopes of longevity but he had the ears and the end of 1 hand chewed off in under 2 hours, am I disappointed…yea a little but he has gotten so much joy out of it that it’s made me really happy to have bought it anyway, see he’s my Service Dog so he spends a lot of time being so serious and working that he needs any outlet for spending energy possible and he’s so happy with it that it makes me happy. As I’m writing this he’s asleep with his head in my lap and Billy right next to him looking very tired and happy and that my friends is worth all the beans in the world.

Great except for one small flaw
Color: Regular - Beak, Color: Regular - Beak
Our dog likes to get at the juicy innards of every toy we buy him. We tried this one as it promised to be "bullet proof". It lasted about a week which in fairness is 6.5 days longer than most of the toys we buy last. He ripped off the wings which was to be expected and not an issue. It took him another 6 days to finally locate a weak point and break in. It appears that the tag is not made of kevlar but merely sewed on. I guess it would be better if they had just sewed it on top but they made it part of the overall structural integrity. This provided a small area of weakness which our dog located and proceeded to exploit. It's like having the death star but installing a small thermal exhaust port that allows for access to the very core of the station. Makes little sense. Overall I am pleased with the overall sturdiness but in the end this toy had a small design flaw that my dog was able to locate and exploit in his neverending quest to gain access to and eat polyester fiber stuffing

STRONG AS A MONSTER (albeit a cute one)
Color: Large - Billy the Beast Monster, Color: Large - Billy the Beast Monster
My aggressive chewer ate the adorable monster's ear off on the first day, but who cares? The body of the monster has been indestructible so far (one week). My 7 month old pup cbews it for a good 10-15 minutes at a time several times per day. Great quality product and outlasting all the other toys I bought (which she destroyed in 10 minutes - even the ones rated "Level 4 toughness" from Walmart. I think it's hilarious in my photo that the monster's expression perfectly shows his disappointment about missing an ear, LOL.
