GekkoScience KBOX
22 TH/s that heats the room

A whole Bitcoin miner in one steel box — power supply, Linux controller, WiFi and fans already inside. About 330W at the wall, 38-47 dB, and the waste heat is the point: it warms the room it sits in.

WHAT ARRIVES

One box. Nothing else to buy.

Most home miners are a board that needs a power supply, a controller, a fan and a case before they are a machine. The KBOX arrives as the machine.

1

Plug it into a wall socket

The 93% Meanwell supply is already inside, on 120 or 240VAC with its own on/off switch. No brick, no proprietary lead, no separate PSU to size.

Minute one
2

Open it in a browser

An integrated Linux controller runs the web interface over Ethernet or 2.4/5 GHz WiFi. Pick High, Medium or Low, or edit the presets yourself.

Minute two
3

Point it at your own address

Solo against your own node, an open solo pool, or a regular pool for steadier payouts. The payout address is yours either way.

Minute three
This is not a pre-order. The KBOX is a finished product that GekkoScience has been shipping and reviewers have already taken apart on camera. Batch 1 is allocated inventory going out end of August, not a concept, and every photo on this page is a real unit rather than a render.

End of August
Batch 1 opened on Aug 3, 2026 and is allocated. These are production units from a finished design, not a first run — GekkoScience have been shipping the KBOX and four independent channels have already reviewed it on camera. Units go out at the end of August.
WHAT YOU GET

One machine, one price, nothing to configure.

Every KBOX is the same 22 TH/s machine with the same internals, the same built-in power supply and the same case. There is no edition to pick and no options to price up.

A 93% efficient Meanwell supply, 120 or 240VAC, with its own on/off switch on the back. Nothing to size, nothing to source, nothing dangling off the side.
KBOX web interface
A real controller, not a dongle
An integrated Linux controller runs the web config and a live stats display, over Ethernet or 2.4/5 GHz WiFi. No host PC, no USB hub, no Raspberry Pi to babysit.
KBOX steel and aluminium case
Safe enough for a living room
Fully enclosed steel and aluminium with a 7 mm hex-grid faceplate small fingers cannot get through. Independent fuses on the mains supply and the hashboard DC bus, and hashing stops if either fan fails.
KBOX RGB modes
It looks like a stove, on purpose
RGB modes include Embers and Woodstove, plus weather-matched colour, Rainbow and Breathe, all on a remote. The heat is real; the fire is the joke.
15.0 J/TH
And that is the whole machine.

Efficiency is watts divided by terahash, and it is what decides your power bill. At 330W for 22 TH/s the KBOX runs at about 15.0 J/TH, near the front of everything we sell — and it gets there with the power supply, controller, WiFi and case already counted in. GekkoScience quote down to 13 J/TH once you tune it yourself.

WHO BUILDS IT
GekkoScience is an electronics hardware manufacturer and engineering design consultancy in north-central Missouri, in business since 2012 and run by the bitcointalk engineer known as Sidehack. He started it out of Missouri University of Science & Technology in Rolla, building one and two chip USB stick miners from salvaged ASICs, and it grew into a fourteen-year line of home mining hardware — the Compac sticks, the Terminus pods, the GekkoAxe, and now the KBOX. It is a small shop that designs, builds and supports its own boards in America, which is why the KBOX is a finished appliance rather than a bare board with an accessory list.

STRAIGHT ANSWERS

What you're actually buying

It is not the cheapest hashrate we sell
At $800 for 22 TH/s the KBOX is about $36 per terahash. The Magic Miner 40T is $16. What you pay the difference for is a finished, quiet, safe appliance with the power supply and controller already in it, made in America. If raw terahash per dollar is the only thing you care about, buy the 40T instead and we will still be happy.
It is a heater as much as a miner
Roughly 330W of electricity goes in and roughly 330W of heat comes out, into whatever room it is in. That is a real space heater. In winter it is the best argument for the machine. In August, in a small room, it is something to plan around.
Mining is a lottery in solo mode
Point it at a pool and it pays steadily and small. Run it solo and it pays in whole blocks or not at all. 22 TH/s gives you a real, recurring shot. It does not guarantee one.
Difficulty and price move
Bitcoin difficulty and price both affect what this earns. We publish honest expectations and never quote you an ROI.

Questions people ask

How loud is it, really?

Altair put a meter on one on camera and got 38 to 47 dB depending on the preset, which is somewhere between a quiet room and a fridge. It is speed controlled fans in a fully enclosed case, not a datacentre blade. The Low preset is the quiet one; High is the loud one, and loud here still means you can hold a conversation next to it.

How much power does it pull, and do I need a special outlet?

About 330W at the wall on the High preset, less on Medium and Low. That is an ordinary wall socket on a normal cord. It takes 120 or 240VAC, so it runs anywhere in the world without a converter. No dedicated circuit, no proprietary brick.

Do I have to buy a power supply or a controller?

No. A 93% efficient Meanwell power supply and an integrated Linux controller are already inside the case, along with WiFi, Ethernet, the fans and the display. The box on your doorstep is the whole machine plus a power cord.

Will it actually heat a room?

Yes, and that is deliberate. Essentially all 330W ends up as heat in the room, the same as any electric heater of that size. GekkoScience call it a hash heater for a reason, and the RGB has an Embers and a Woodstove mode to lean into it.

Do I need my own Bitcoin node?

No. Point it at your own node, at an open solo pool, or at a regular pool for steadier payouts. Either way the payout address is yours.

What if I change my mind?

Refunds are allowed, always. You get a full refund any time before your unit ships, no questions asked, and exchanges are allowed too. Once it has shipped, the standard 30 day warranty and returns policy applies.

Where does it ship, and when?

Worldwide, at the end of August. It runs on 120 or 240VAC so there is no region-locked variant to get wrong, and we ship with the cord matched to your address. If that date moves we post it here and email you.
