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.

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.
