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.

Sturdy, smaller sized supply caddy-well crafted.
Size: 5 Tiers (5.1"D x 39.2"H), Color: Rustic Brown + Classic Black
Why did you pick this product vs others?: Started out asking friends what they use for a cart - to clear stuff off their drawing boards, desks, etc. I've got an unusual amount of "things" in my workspace, and although I keep paints in a separate caddy to one side on my drafting table, the topside clutter was getting unbearable. Due to people giving me things, my interest in a few crafts, and just junk. Mainly I use the my wonderful, old, 1950s school cast-off - drafting table for painting - as it tilts and I have an edge on it. I've been wanting to also replace the top board, too. The usual caddies didn't appeal to me - the plastic ones annoy me as I can't see in the bins at what I should easily be able to reach and cannot see-though the opaque plastic. As I purged the clutter I realized I needed way less than I had and that's how I determined the size of the rolling cart. I use my spare garage and I have a lot of space, but that's the kicker - the more space you have the more things you could have, too. That's my reasoning for choosing a smaller cart. Narrow, to keep it minimal. Black metal to hide dirt. Wheels? a bonus - I'll just pull it back and forth out of its space--it's not going to be a trolley. I picked this one out of several because of price, and size, but I may come back at another time to purchase a larger one for the coat closet - mittens & hats & ski goggles & stuff.  I am going to look at the same brand, but I'm also going to choose one with sturdier wheels.  THIS CART was easy to put together, no issues at all. I didn't time myself - it took a while - under an hour is my best guess due to all the small pieces. I know it was manufactured this way to be able to fit it in as small a space-box for shipping, as possible. It was tedious, but certainly not an issue. Just lay it out the way the diagrams show you - they are perfectly done. It's sturdy enough as a supply caddy - you can't sit on the thing, or let kids romp on it but it's stiff in all the right places and the handle is perfectly placed. The top of it will hold my tablet or phone - next to my table; it's not a decor piece, but the black finish does look rather nice -with the faux wood/wood laminate top. Basket depth is well thought out, too. Coffee cans with paint brushes, some other tools, but the best part is no more clutter taking up space on top of my drafting table and I can actually use it the way it was intended!

Perfect fit

I was hesitant about ordering after reading some of the reviews, however it was exactly what I was looking for. It turned out to be a good investment, however the reviews were correct about the wobbly wheels. For the $ the wheels should have been made with better quality, which would have given the product more steadiness. Overall, a good product and it was easy to put together.

Great addition to my kitchen
Size: 5 Tiers (8.7"D x 39.2"H), Color: Rustic Brown + Classic Black
This fit my odd space between the wall and stove perfectly in height and width, I just wish it was long enough to go to the back wall. I found a tall shelf to fill the gap. The look of the cart accents my decor and will continue to match after I paint my cabinets. Assembly was straight forward and easy. Took about 10 minutes. The instructions were clear. The wheels don't like my tile for some reason so I'll have to get new ones from the hardware store, something that isn't plastic. This isn't an issue for the cart necessarily, my floor wasn't the best install. This cart works well on my other floors.
