Loki Kit - Run a Bitmain X19 Antminer From a 120 V Outlet

Description

The Loki Kit is a power conversion kit that lets you run a Bitmain X19-series Antminer from a 120 V outlet instead of the 200–240 V supply the machine is built for. It is an installation and siting tool: it solves the problem of having the miner but not the circuit.

What the Loki Kit does — and what it does not

We are going to be direct about this, because an earlier version of this page said the kit “boosts hash rate performance and mining efficiency” and that is not true.

It does not increase your hashrate. A converter moves energy from one form to another. It does not create energy, and hashrate comes from power and silicon, not from wiring.
It does not make the machine more efficient. Every conversion stage loses a little to heat, so a converted setup draws marginally more at the wall for the same work, not less.
In practice you will run the machine derated. A standard 120 V household circuit cannot deliver the roughly 3,250 W an X19 wants at full tilt. You turn the machine down in firmware to fit the circuit, and you get proportionally less hashrate for it. That is the trade, and it is a perfectly reasonable one — it is just not a performance upgrade.

So when is it the right buy?

When the alternative is not running the machine at all. If you have an X19 and a 120 V garage outlet, this gets you mining this week instead of after an electrician’s visit. It is also genuinely useful for bench testing and diagnostics, for temporary siting, and for anyone relocating gear who needs it powered somewhere without three-phase or a 240 V drop. What it is not is a substitute for a proper circuit if you intend to run the machine at its rated output long term — for that, get the 240 V supply installed.

Safety, because this is the part that hurts

Do not exceed the rating of the circuit you are plugging into. A 15 A 120 V circuit is about 1,800 W, and continuous loads should sit well under that. Anyone telling you that you can pull a full X19’s worth of power through a domestic 120 V socket is describing a fire, not a setup. Derate the miner, use properly rated cordage, and do not daisy-chain it. If you are unsure what your circuit can carry, ask us before you order — and if we think you need an electrician rather than a converter, we will say so.

Nothing that is not listed above. Cords, controllers, brackets and spares are only included when this listing names them — if you need to know before you pay, ask on +1 (781) 577-0377 or ns@ingmining.com and we will confirm in writing what is physically in the crate

Questions buyers ask about this part

Is this a complete, working machine?

No. This listing is on the parts and repair shelf, which holds both brand-new spares and bench tools and as-is units sold for repair. Which of those this one is, is stated in the description above — read it before you order, and ask us on +1 (781) 577-0377 or ns@ingmining.com if anything about compatibility with your fleet is unclear. We would rather answer the question than take a return.

What should I check the day it arrives?

Photograph the pallet or box before you open it, keep the packaging, and run the 48-hour acceptance test straight away. Freight claim windows are short, and a fault found on day two is a conversation while a fault found on day thirty is an argument. Our own six-step bench procedure is published in full, so you can repeat exactly what we did.

Shipping cost for this exact item, and how warranty and returns work here, are answered in the Shipping & buying tab on this page. Anything else, ask a person on +1 (781) 577-0377 or ns@ingmining.com — we would rather talk before you buy.

Add this to the machine’s price before you compare anything

The number that decides a used purchase is landed cost per terahash, and a conversion kit is part of the landed cost. On our $159.99 used S19 this $99.99 kit is 62% of the machine, taking a $1.68-per-terahash purchase to about $2.74 before freight. That is still far below the $17.14 per terahash of a new S21 Pro 245T at $4,200, so the used case survives it easily — but it survives it as a worse number, and buyers who compare a bare miner price against a new machine’s are not comparing the same thing.

Then apply the derate. A 120 V circuit cannot deliver what an X19 wants, so the machine runs turned down: less hashrate for the same capital, which pushes cost per terahash up a second time. Two adjustments, both in the same direction. If the honest answer is that your site cannot carry the machine, the cheaper fix is usually a 240 V circuit or a miner built for 110 V — the Avalon Q is the sensible example. how to buy a used ASIC miner works landed cost per terahash through end to end.

Where this listing sits

This one is on the parts and repair shelf. That shelf holds two different things: brand-new spares and bench tools, and as-is units sold for repair. Which of the two this listing is, is stated in its own description — read it before you order.

What our grades mean

These are the only words we use, and each one means a specific thing. They are not interchangeable and we do not soften them to move stock.

New	Unused stock. Factory sealed unless the listing says otherwise — “new, open box” means exactly that, and the listing will say it.
Tested working	Second-hand, and it ran on our bench at the hashrate the listing states. We measured it; we are not repeating what the last owner told us. Expect cosmetic wear.
Refurbished	Tested working, plus work done: cleaned, thermal paste and fans dealt with, failed components replaced. The listing says what was actually done to that unit rather than using the word as decoration.
As-is / for parts	Sold with no working claim at all, at a price that reflects it. Buy these to repair or to harvest. If a listing says as-is, assume it does not hash until you have proved otherwise.
Untested	We have it, we have not powered it, and we are not going to pretend we did. Rarer than as-is and always stated explicitly.

What a grade here does not mean

Cosmetic wear is not a fault. Dust, scratches, scuffed labels and discoloured plastics are normal on hardware that has been earning. We photograph what we have; if the pictures matter to you, ask for more and we will take them.
A grade is not a warranty. Warranty terms are stated per listing, never per store — see the Shipping & buying tab. A tested-working grade describes what the machine did on our bench, not what we owe you in six months.
A boosted hashrate is not a spec. Where a unit ships on tuned firmware we say so and we give the factory figures too, because overclocking raises power faster than it raises hashrate — a tuned machine is less efficient per terahash than stock, not more.
We will not invent a grade to fill a field. If a unit came in without history and has not been through the bench, its listing says that.

How the grade gets decided

A used-hardware seller who will not tell you how they test is asking you to take the grade on trust. Ours is published: the six-step bench procedure every machine goes through, and the five measurements that get recorded — per-board hashrate, chip count, measured wall power rather than the nameplate figure, hardware error rate, and temperature under sustained load. When it reaches you, run the 48-hour acceptance test straight away, while the freight claim window is still open.

Buying second-hand for the first time? How to buy a used ASIC miner without getting burned is the long version, written from the repair bench rather than from a spec sheet.

Shipping

Shipping this item inside the United States costs $49.99 by UPS Ground — that is the rate the checkout will charge, read from the store’s own shipping settings, not an estimate. Orders ship within 7 business days.

Outside the United States the checkout quotes a flat international rate. On multi-unit or pallet orders, contact us before ordering so freight to your destination can be confirmed properly. What to check when the pallet arrives, and how a freight claim works, is covered in the mining hardware shipping guide.

What to do the day it arrives

Photograph the pallet or the box before you open it, and keep the packaging until you are satisfied. Freight claim windows are short, and damage found on day two is a conversation while damage found on day thirty is an argument.

Then run the 48-hour acceptance test straight away, while that window is still open. It is the same ground our own bench covers, so you can compare like for like: how the grade on this listing was arrived at, and the five measurements we record, are set out in the Condition & grading tab on this page.

Condition, warranty and returns

Condition: Repair part or bench tool — this shelf holds both new spares and as-is units, so read the condition stated in the description.

Warranty is stated per listing, not across the catalogue. Some units carry a manufacturer term and say so above, naming the term and the date it runs from. Many units, particularly used and AS-IS stock, carry none, and those listings do not claim one. There is no blanket warranty covering a catalogue that runs from sealed factory stock to a hashboard sold for parts. For what a mining warranty normally covers, see ASIC miner warranty explained.

Returns: ask for the terms on this unit before you pay. No single returns window is published for the whole store, because the sensible terms on a tested working machine and on a board sold AS-IS for parts are not the same terms. Email or call and ask what applies to this exact item — it is a two-minute conversation and a great deal cheaper than a dispute.
