4ms Pod20 (2022–)

A tiny armored tank for your favorite Eurorack module — no soldering, no stress, just plug and play.

Overview

If you’ve ever stared at a half-empty desk, a single Eurorack module gathering dust on a shelf, and thought, “I just need a way to make this *work*,” the 4ms Pod20 (Powered) is your answer. It’s not a synth, not a module, not even a full case in the traditional sense — it’s a 20HP armored lunchbox that turns one or two orphaned modules into a self-contained instrument. Built since at least June 2022 (first spotted at Thomann), this little black slab from 4ms is the minimalist’s gateway to modular: no chassis assembly, no power distribution headaches, just anodized aluminum, threaded rails, and a clean internal supply ready to go.

What it is, fundamentally, is a powered Eurorack enclosure — compact, portable, and dead simple. It’s the kind of thing you can toss in a gig bag, set next to a laptop or drum machine, and use to run a single effects processor, a voice, or a utility module without committing to a full rack. It doesn’t try to be everything; it tries to be *enough*, and it nails it. The Pod20 gives you 20HP of usable space, a depth of 34.2mm (1.34") for modules (which rules out the deepest modules, but fits the vast majority), and a clean, threaded M3 rail system so you can mount modules securely with the included stainless steel screws. It weighs next to nothing — 170 grams — but feels dense, like a chunk of precision-machined unobtanium.

And the power? It’s built in, low-profile, and outputs a solid 700mA on +12V, 280mA on -12V, and 200mA on +5V — more than enough for a couple of modest modules. You feed it with a 15–20VDC barrel jack (2.1mm, positive tip), and it even has two input jacks so you can daisy-chain multiple Pods together. That’s where the 4ms ecosystem starts to shine: you’re not just buying a case, you’re buying into a modular *system* that can scale from a single voice to a desktop constellation. Want to expand? Grab a Pod26 or Pod32. Need more power? The Pod60 bumps up to 1.4A on +12V. But even solo, the Pod20 holds its own.

Owners report it’s “extremely practical and reliable,” “compact and light, making it ideal for mobile setups and smaller studio environments,” and praise the “robust construction from sturdy aluminum.” One reviewer put it plainly: “This product fulfills its function perfectly, well-built, no issues to report, it seems serious!” And while it’s not cheap for what it is — $99 is a premium price for a 20HP case — the build quality justifies it. No sharp edges, no wobble, no flimsy plastic. It’s all black anodized aluminum, with rubber feet to keep it planted, and the kind of fit and finish that says “engineered,” not “assembled.”

But let’s be real: it’s tiny. You’re not building a full synth here. You’re making a statement — or a sound — with minimal real estate. And if you’re running multiple modules, you’ll need a multi-power cable accessory to share the rails, because the internal supply only has two connectors. Also, the power input is on the back, and depending on your cable, it might feel a bit cramped — one reviewer noted the jack placement can get “a bit tight.” And yes, the power brick? Not included. You’ll need the 4ms Power Brick 45W (art. 544815) or a compatible 15–20VDC supply, plus a barrel cable. That’s an extra cost, but it’s standard for the format.

Still, for what it does, the Pod20 is a quiet triumph of focused design. It’s not trying to impress with flash or features. It’s just there, doing its job, looking good, and letting your modules shine.

Key Features

Built-In, Daisy-Chainable Power Supply

The Pod20’s biggest trick is having a power supply already installed — no DIY soldering, no external distribution board. It delivers 700mA on +12V, which is generous for a case this size, and splits the power across two connectors so you can run two modules without issue. But the real magic is in the daisy-chaining: with two barrel jacks on the back, you can link multiple Pods together and power them all from a single brick. That means you can stack a Pod20 for a filter, a Pod26 for a sequencer, and a Pod32 for a VCO, all running off one supply. And if you’re already using 4ms Row Power, good news — the Pod20 plays nice with that system too. It’s a small detail, but it turns a standalone case into part of a scalable ecosystem.

Threaded Rails & Secure Mounting

No rails to install, no nuts to lose — the Pod20 comes with M3 threaded holes built right into the aluminum frame. That means you can mount modules directly with the included stainless steel pan-head screws (10 of them, 8mm long), and they won’t budge. It’s compatible with M3 Knurlies too, if you’re into that clean, tool-free look. The rails are precision-cut, the threading is clean, and there are no sharp edges to snag cables or fingers. It’s the kind of detail that makes setup feel satisfying, not fiddly.

Compact, Rugged Aluminum Enclosure

At just over 4 inches wide and under 1.5 inches deep, the Pod20 disappears on a desk — but it doesn’t feel cheap. The entire chassis is machined from 100% anodized aluminum, finished in a sleek black that resists scratches and fingerprints. It’s lightweight (only 170g), but the density of the metal gives it a reassuring heft. Four adhesive rubber feet keep it from sliding, and the overall construction is tight — no creaks, no flex, no wobble. One reviewer put it best: “cleanly processed and robust,” with “no wobbling.” It’s not just a case — it’s a little fortress for your module.

Scalable, Modular Design Philosophy

The Pod20 isn’t meant to stand alone forever. It’s part of a family: 20HP, 26HP, 32HP, and 60HP variants, all sharing the same design language and power system. You can mix and match them with desktop synths, pedals, or other gear to build a custom setup that grows with you. Need more space? Add a Pod. Need more power? Upgrade to the Pod60 or bring in Row Power. It’s a refreshingly modular approach to modular — instead of committing to a 84HP case on day one, you start small and expand only what you need.

Collectibility & Value

The 4ms Pod20 (Powered) carries a current market price of $99.00 — a premium for a 20HP case, but one that reflects its build quality and integrated power. It’s not a vintage item yet (production began in 2022), so collectibility is more about utility than rarity. There’s no data on common failures or long-term reliability issues, but early reviews suggest it’s solidly built and problem-free. The main cost consideration isn’t the Pod itself, but the required power brick and cable — both sold separately. But for musicians who want a no-fuss, portable way to integrate Eurorack into their workflow, that price buys peace of mind: a ready-to-go, reliable enclosure from a respected brand.
