ASIC Miner Support: What We Test, What Ships, and What to Do When Something Is Wrong
Call +1 (781) 577-0377 or email ns@ingmining.com. A person who has had these machines apart answers — before the sale as well as after it.
This page answers what people actually write in about: what a machine goes through before it gets listed, what the checkout charges to ship it, what to do in the first 48 hours after it arrives, what happens when something is wrong, and how to check out who you are sending money to. Every figure below is read from the store’s own settings or from a public record, and each one says where it came from.
Before you buy: ask what the terms are on that exact unit
Warranty and return terms here are stated per listing, not per store, and that is deliberate. Some units carry a manufacturer term, and where they do the listing names the term and the date it runs from. Used and AS-IS units generally carry none, and those listings do not claim one. There is no single store-wide returns window published, because the sensible terms on a tested working machine and on a hashboard sold for parts are not the same terms, and one blanket policy would be untrue at one end or the other.
So ask before you pay. Call or email with the listing in front of you and we will tell you what applies to that unit — what was measured on the bench, what the condition grade means, and what happens if it turns up dead. It is a two-minute conversation and a great deal cheaper than a dispute. For the background on what a mining warranty normally covers and where the fine print sits, see ASIC miner warranty explained.
What “per listing” actually looks like, on listings you can go and read
Told that terms are set per unit, a reasonable buyer wonders whether that is a policy or an excuse. It is checkable. Much of this stock is also listed on our eBay storefront, where the return terms have to be published on the listing itself. Across 24 of the 48 listings live on it, read on 14 August 2026:
- 17 of 24 — 30-day returns, buyer pays return shipping. Tested working S19s and S19k Pros, a KS5 Pro, two tested-working S19 Pro hashboards, hashboard test fixtures, 110V power kits, a lot of 20 machines, an industrial drive — and one S19 XP Pro hashboard listed explicitly AS-IS for parts.
- 7 of 24 — no returns accepted. A NerdQaxe++ solo miner, two Fanuc teach pendants (one of them new, open box), a hashboard tester, a hashboard EEPROM editor, a new printer toner cartridge and a 12 kW water-cooling radiator.
Read those two lists again and the useful thing is what they are not: the split does not follow condition. On eBay an AS-IS hashboard came with 30-day returns and a boxed new item came with none, because the terms follow the individual unit and what it cost to acquire, not the shelf it sits on. A single store-wide window would have to be wrong at one end of that range or the other. So the answer here is the same answer, and now you can audit it: ask what applies to your unit before you pay, and we will put it in writing.
What that evidence is not. Those are eBay’s terms on eBay’s listings and they do not transfer automatically to an order placed on this site — the two channels are priced, shipped and protected differently. Treat it as evidence of how this seller handles returns, not as a policy this website has published. If a marketplace’s own protection is what you want, both have one and neither is ours to grant: eBay’s Money Back Guarantee covers eBay orders including the no-return listings, and Amazon’s A-to-z Guarantee covers orders through our Amazon seller account. Buying here means dealing with us directly instead, which is why the phone number is at the top of this page.
What the condition categories mean here
- New — factory stock. Where a unit is still inside a manufacturer warranty term, the listing says so and dates it.
- Used — a machine somebody else ran hot for two or three years, bench-tested here and described by what it measured, not by what it should measure.
- Need Parts — repair and harvest stock, described by what is wrong with it. A board that only partly hashes is described as a board that only partly hashes.
They are separate categories on this store precisely so a parts unit cannot be mistaken for a working one. Where a figure genuinely is not known for a particular unit, the listing says it is unknown rather than picking the flattering option.
What a machine goes through before it gets listed
A used-hardware seller who will not tell you how they test is asking you to take the grade on trust, so the procedure is published in full: the six-step bench procedure, step by step, with what each result rules in or out. Five things get recorded, and these are the five that matter:
- per-board hashrate
- chip count found per board
- power measured at the wall, not the nameplate figure
- hardware error rate
- intake and board temperature under sustained load
Two of those are the whole game. Real hashrate and real watts are exactly the numbers a seller has an incentive to quote optimistically, which is why they are measured at the wall instead of copied off a spec sheet.
What shipping costs
These are the rates configured in the store’s own checkout, read from the settings rather than estimated. Everything ships from the United States by UPS Ground, and orders ship within 7 business days.
| What you are ordering | Shipping within the United States |
|---|---|
| A single machine, hashboard, power supply or part | $49.99 per unit |
| A lot of 5 machines | $299.99 |
| A lot of 10 machines | $549.99 |
| A lot of 100 machines | $3,449.99 |
The per-unit rate covers single machines, hashboards, power supplies, testers and parts, and on a listing that carries a price and an add-to-cart button it is the number you will be billed.
The three lot rows are configured rates that no order can currently trigger. Since 11 August 2026 every multi-machine lot on this store is quoted rather than sold through the cart, so freight on a lot comes back on the same quote as the machines. They stay in the table because they are what the settings hold and because they show why a lot of 100 is not a hundred times the single-unit rate — lots move as freight rather than as parcels — not because a checkout will charge one today.
The same is true of the price. 70 of the 145 listings on this store carry a price and an add-to-cart button; the other 75 are quoted — the eleven multi-machine lots and most of the current-generation new stock (read from our own catalogue on 14 August 2026). A listing with no price is not a listing with a problem: it means the number comes back against your quantity, the condition you can accept and where it is going. Call or email with the listing in front of you and you will get one.
Outside the United States the checkout quotes $250.00 per unit — the rate is multiplied by quantity, not a flat charge for the whole order. On anything larger than a single machine, contact us before you order. A pallet of miners crossing a border is a freight job with customs paperwork, and it needs quoting properly rather than taking a flat rate off a web form.
Sales tax is charged at 6.25% on orders shipping to MA, which is where the business is based. Orders to other states are not charged sales tax at checkout.
If you are working out landed cost, crating, insurance, customs paperwork or what to do when a pallet arrives damaged, the mining hardware shipping guide covers all of it. For fleet quantities, freight and delivery scheduling are part of the quote — see bulk mining hardware.
The first 48 hours after it arrives
Do this before anything else, because the window in which a fault is somebody else’s problem is short:
- Photograph the pallet or box before you cut the wrap. A damage claim without a photograph of the packaging as delivered is a much weaker claim.
- Keep the packaging until the machine has run a clean 48 hours.
- Run the acceptance test — the full procedure is written up at acceptance-testing a miner you just received: physical inspection, PSU check, network and firmware, hashrate against the listing, temperatures, then an extended load run.
- Tell us straight away if something is wrong, while the freight claim window is still open.
If something is wrong
Tell us early and tell us specifically. What actually speeds up a fix, roughly in order of usefulness:
- photographs of the packaging as delivered, if there is any chance of transit damage
- the serial number and the listing the unit came from
- a screenshot of the miner’s status page — hashrate per board, chips found per board, hardware error rate and temperatures
- the kernel log, which usually names the failing board before anything else does
- what power supply it is on and at what voltage — a machine specified for 220–240 V will not behave on a 110 V circuit, and that is the single most common “dead on arrival” that turns out not to be
The four things we stock deepest are fans, power supplies, control boards and hashboards, which is a fair proxy for what actually fails on this hardware. The parts, testers and AS-IS category is the same shelf we repair from, and the parts compatibility guide covers what swaps into what.
Whether a repair is worth doing is arithmetic rather than sentiment. A hashboard restores one third of a three-board machine, so the rule we use ourselves is repair the board if a board costs less than a third of what a whole working machine costs. On a cheap lot-bought S19 that maths says harvest it; on a current-generation machine every fault on the ladder is worth fixing.
Running it: power, noise and hosting
The most useful thing we can tell a first-time buyer is that the machine is usually not the problem — the electricity price is. Break-even electricity rate is hashprice divided by (24 × J/TH), and hashrate cancels out of that entirely, which is why a cheap old machine on expensive power loses money faster than an expensive new one does. Work out your own number before you buy anything; the buying guide has the arithmetic.
If your power is not genuinely cheap, hosting is the question to be asking instead. Before signing anything, get written answers on who pays for repairs, what the uptime commitment’s actual remedy is, and how curtailment is handled — a flat per-machine monthly rate is where most of the unpleasant surprises live. Types of mining farm compares the models and cloud mining versus owning the machine covers why owning the hardware is usually the better end of that trade.
Whoever ends up hosting them, the work either side of that contract is ours: deployment, pool and network setup, Braiins OS or VNish tuning, offline alerts, and board-level fault-finding when a machine stops hashing — ASIC mining consulting sets out what it covers. The hosting agreement itself is between you and the facility, and this page is not going to pick one for you. What we can give you going into it is what the machine measured at the wall on our bench, which is the number a hosting dispute turns on.
Checking us out before you send money
ING Mining LLC, Hanson, Massachusetts. ING MINING® is a registered United States trademark — Registration No. 7,989,340, serial 97806036, registered 21 October 2025 and live on the Principal Register. The whole file is public: how to verify it in about thirty seconds.
We also trade on eBay as ingmining, where the trading record is published by somebody other than us: 100% positive feedback and 5,600+ items sold, and over the last 12 months 231 positive, 7 neutral and 0 negative ratings across 1,438 published buyer ratings in total, with detailed seller ratings of 4.8 for accurate description, 4.9 for shipping cost, 5.0 for shipping speed and 5.0 for communication. Those figures were read from eBay on 14 August 2026 and they move; check them yourself rather than taking our word for it. For a used-hardware dealer, “accurate description” is the rating that matters, and it is the one we would want you to look at.
If you would rather buy inside a marketplace with its own buyer protection, the eBay storefront carries much of the same stock. Either way, talk to us first about the specific unit.
The same is true on Amazon, and that record is worth reading precisely because it is not all five stars. Amazon’s own seller profile for this account shows 4.8 out of 5 across 214 lifetime ratings, 96% positive lifetime — 87% five-star, 9% four-star, 1% two-star and 3% one-star — read on 14 August 2026. The one-star and two-star entries are visible on that page along with what happened next, which is more use to you than an average. Amazon publishes it, we do not, and it moves.
Two more records exist and neither of them is ours either. Google publishes a business profile for ING Mining showing 5.0 out of 5 across 12 reviews, filed under “Mining equipment” with the same phone number as the top of this page — read 14 August 2026. Twelve is a small count and they are not recent, but they are signed and several name the machine that was bought: look it up. That link opens the profile itself rather than a search page. Google publishes our Hanson address and phone number on it — the same address that is on our trademark registration and on the Trustpilot profile below.
Trustpilot is the one to read if you want the unflattering version. The profile was claimed in September 2025 and shows 3.8 out of 5 across 4 reviews — three five-star and one one-star — read 14 August 2026. The one-star says only that its author was scammed; the reply under it is public, and it says no order, payment or support request could be found under that name and asks for an order number and a date so it can be looked into. Trustpilot itself records that this account has replied to 100% of its negative reviews. Four reviews is not a trading record, which is why the eBay and Amazon numbers above carry more weight — but it is published, it is one search away, and you should get it from us rather than find it later. Read all four.
