Buy Antminer S19k Pro – 115 TH/s, tested, from €419
Buy Antminer S19k Pro: 115 TH/s tested from €419/unit (1/3/10: €449/€439/€419), 23 J/TH, optional Braiins OS+, German stock, 48 h delivery (Germany).
Buy the Antminer S19k Pro from German stock: the used, load-tested Antminer S19k Pro 115 TH/s costs €449 as a single unit and from €419 per unit from ten – 115 TH/s at 2645W, 23 J/TH. The units are physically in our warehouse in Bavaria, customs-cleared, and ship insured within 48 hours (business days, Germany).
With 23 J/TH the S19k Pro is the most efficient air-cooled S19 and the model we recommend most often to buyers on a paid tariff: it costs a fraction of an Antminer S21 but needs far less energy per terahash than the Antminer S19j Pro. Below you find the price ladder, the specs, electricity cost per day, how buying here compares with a China import, and the FAQ. The Antminer S19 comparison guide covers the whole series; the buy Antminer overview lists every Bitmain model we sell.

Antminer S19k Pro in detail: the value pick of the S19 generation
Bitmain released the S19k Pro as the late, cost-optimised member of the S19 family: fewer chips per hashboard than the S19 XP, but the same efficiency class of about 23 J/TH. In practice that means 115 TH/s for 2645W – less power than an S19j Pro (3068W), which only delivers 104 TH/s. Per terahash you pay about a fifth less electricity than with the S19j Pro, and the difference shows up on every monthly bill.
Only the 115 TH/s version is currently in stock. Every unit runs a full load cycle on our own power supply before it ships; we check that each hashboard delivers, that fans and PSU behave under real load, and that boards, connectors and case show no damage or corrosion. The achieved hashrate is logged. Optional Braiins OS+ (free during the autumn promo, otherwise €20 per unit) adds autotuning and undervolting for quieter, more efficient operation – read our mining software notice before changing firmware.

Antminer S19k Pro electricity cost per day and month
Electricity is the only running cost you can pin down before buying. The Antminer S19k Pro 115 TH/s draws 2645W, i.e. about 63.5 kWh per day in continuous operation. The formula is simple: watts × 24 h ÷ 1,000 × your price per kWh. The table shows the result for three typical tariffs.
Cost only, incl. VAT on the tariff. Mining revenue changes daily with Bitcoin price and network difficulty, so we do not publish fixed profit figures.
Whether the machine pays off is then a question of revenue at current difficulty versus this cost. Run your own scenario with the Bitcoin mining calculator (revenue, break-even, payback at today's difficulty) and the electricity cost calculator (daily cost per model at your tariff) before you order.
| Electricity price | Consumption per day | Cost per day | Cost per month (30 days) |
|---|---|---|---|
| 10 ct/kWh | 63.5 kWh | €6.35 | €190.44 |
| 20 ct/kWh | 63.5 kWh | €12.70 | €380.88 |
| 30 ct/kWh | 63.5 kWh | €19.04 | €571.32 |

Buying an Antminer S19k Pro from us vs. direct import from China vs. private purchase
A Antminer S19k Pro 115 TH/s can be bought three ways: from a dealer in Germany, imported directly from Asia, or second-hand from a private seller on classifieds or eBay. The table shows the differences that matter in practice – customs, delivery time, statutory warranty, invoice and who you can call when something goes wrong. It contains no opinions, only what each route can and cannot provide.
| Criterion | Mining Technologies | Direct import from China | Private purchase (classifieds/eBay) |
|---|---|---|---|
| Customs / import VAT | None on top: stocked units are customs-cleared in Germany, models from our HK warehouse are imported and cleared by us. Prices incl. 19% VAT. | 19% import VAT plus customs duty where applicable, handled and paid by the buyer on arrival. | None (goods already in Germany), but usually no invoice and no VAT to reclaim. |
| Delivery time | Antminer S19k Pro 115 TH/s: in stock in Germany, ships in 48 hours (business days, Germany) after payment. | Several weeks (air or sea freight plus customs clearance). | By arrangement, often collection only. |
| Warranty | Statutory warranty for consumers on this used unit. No additional voluntary guarantee. | Depends on the seller; claims are handled abroad and return shipping is at your cost. | Usually excluded between private parties ("sold as seen"). |
| Invoice with VAT | Yes, proper invoice showing VAT; reverse charge for EU business customers with VAT ID. | Foreign invoice without German VAT; import VAT is charged separately. | Usually none. |
| Testing before shipping | Full load cycle on our own power supply with logged hashrate per hashboard. | No independent check before shipping. | Only if you test the unit yourself on site. |
| Contact in Germany | Yes – phone, WhatsApp and email, before and after the purchase. | Support by the seller abroad, usually in another time zone. | No. |
| Payment | Bank transfer, PayPal, Apple Pay, card or crypto – buyer protection where the method offers it. | Usually bank transfer or crypto in advance, no buyer protection. | Cash or transfer in advance, no buyer protection. |
Who the Antminer S19k Pro is right for
- Buyers on a paid tariff between roughly 10 and 20 ct/kWh: the 23 J/TH recover the higher purchase price over the S19j Pro through the electricity bill. This is the S19k Pro's home turf.
- Heat reuse in a workshop, barn or outbuilding: 2645W of continuous load is about 2.7 kW of heat – enough for a mid-sized room – and the miner pays part of the heating bill.
- Small farms of 3–10 units: the volume tiers bring the per-unit price down to €419, all units are the same generation and can be managed with one firmware image.
- Not the right pick if your power is free or nearly free – then the cheaper Antminer S19j Pro wins. For household electricity without heat reuse, more efficient models such as the Antminer S21/T21 are the better choice (from our HK warehouse). With PV surplus or heat demand in a workshop or hall, the S19k Pro is the low-cost option from our German stock.

S19k Pro vs. S19j Pro vs. T21 vs. S21
The S19k Pro sits between the entry-level S19j Pro and the current S21 generation. Prices and stock status from our catalog:
The step from the S19k Pro to the Antminer T21 (19 J/TH) or the S21 (17.5 J/TH) buys another 17–24% less energy per terahash, but at two to three times the purchase price per unit. At long runtimes and paid power that pays off; for a first machine or surplus solar it usually does not. The used Antminer page explains what to check on any second-hand unit.

S19k Pro or S19j Pro – which one should I buy?
The S19j Pro is cheaper (€329 single, €299 from ten units) but uses 29.5 J/TH; the S19k Pro needs 23 J/TH, about a fifth less energy per terahash, and delivers 115 TH/s instead of 104 TH/s. With free or very cheap power the S19j Pro wins on purchase price; on a paid tariff the S19k Pro recovers its higher price through the electricity bill.
How much electricity does the Antminer S19k Pro use?
2645W depending on the unit's hashrate. At an average of 2,645 W that is about 63.5 kWh per day – €6.35 at 10 ct/kWh, €12.70 at 20 ct/kWh and €19.04 at 30 ct/kWh. Revenue depends on Bitcoin price and difficulty; use our Bitcoin mining calculator for your own scenario.
What warranty applies to the used S19k Pro?
Statutory warranty for consumers on used units. We do not add a voluntary guarantee. Every S19k Pro runs a full load cycle on our own power supply before dispatch; hashboards, fans, PSU and connectors are checked and the achieved hashrate is logged.
Can I get the S19k Pro with Braiins OS+?
Yes. Braiins OS+ can be pre-installed when ordering – free during the autumn promo, otherwise €20 per unit. It enables autotuning and undervolting, which lowers power draw and noise at a slightly reduced hashrate. Please read our mining software notice first – changing firmware is your decision and can affect claims against the manufacturer.
Where can I buy the Antminer S19k Pro in Germany?
From Mining Technologies, a German dealer with its own warehouse in Bavaria. The S19k Pro is customs-cleared stock, comes with an invoice showing VAT (reverse charge for EU businesses with a VAT ID) and you have a contact in Germany by phone, WhatsApp or email.
