What is an Antminer?
An Antminer is an ASIC miner made by Bitmain, a Beijing-based manufacturer that has built application-specific chips for cryptocurrency mining since 2013 and is the largest supplier of mining hardware worldwide. "Antminer" is the brand name of the finished machines; the model families are named by algorithm and generation: the S series (S19, S21) and the cost-optimised T series (T21) mine Bitcoin with SHA-256, the L series (L7, L9) mines Litecoin and Dogecoin with Scrypt, and the KS series (KS7) mines Kaspa. Water-cooled variants carry the suffix "Hydro".
Each Antminer is a complete unit: hashboards with the ASIC chips, a control board with Ethernet port and web interface, fans and Bitmain's own power supply. You connect the mains cable and a network cable, enter your pool and wallet in the browser, and the machine mines around the clock – our Antminer setup guide walks through IP address, default password, pool and firmware step by step. The main alternative brand is MicroBT's WhatsMiner.

Antminer series explained: S19, S21, T21, L series, KS series
Bitmain names its Antminers by algorithm and generation. The S series mines Bitcoin (SHA-256), the T series is the cost-optimised SHA-256 line, the L series mines Litecoin and Dogecoin (Scrypt) and the KS series mines Kaspa (kHeavyHash). A higher number means a newer generation with a lower J/TH figure – the amount of energy needed per terahash, which is the number that decides your running costs.
Antminer S19 – the workhorse generation. We stock the S19j Pro (104 TH/s, 3068W, 29.5 J/TH) as a tested used unit from €299 and the S19k Pro (115-120 TH/s, 23 J/TH) from €449. Both ship from Germany in 2–4 business days. The S19 XP itself is not in our range; the Antminer S19 XP page explains the available alternatives. The water-cooled Antminer Hydro (230-473 TH/s, 12-23 J/TH) starts from €1.369 and is ordered ex works.
Antminer S21 – the current efficiency generation. The S21 delivers 151 TH/s at 2650W (17.5 J/TH) for €1.379; the S21+ raises that to 216 TH/s at 16.5 J/TH for €2.149. Both are new, boxed and sourced ex works with a 10–14 day lead time.
Antminer T21 – 190 TH/s at 19 J/TH, positioned between S19 and S21. We list the T21 as a used unit from €1.049 with bulk tiers; availability is currently on request.
L series (Scrypt) – the Antminer L7 (9,05 Gh/s, 3425W) at €1.419 and the Antminer L9 (16 Gh/s, 210 W/Gh) at €3.999 mine Litecoin and Dogecoin simultaneously. KS series (Kaspa) – the Antminer KS7 (36 TH/s, 3300W) costs €1.999. All three are new units ordered ex works.
New or used?
Used: lowest entry price (S19j Pro from €299, S19k Pro from €449), best price per TH/s, stocked in Germany and shipped in 2–4 business days, statutory warranty of 12 months for consumers. New: current generation (S21 €1.379, S21+ €2.149), best efficiency (16.5 J/TH on the S21+ vs. 29.5 J/TH on the S19j Pro), boxed ex works in 10–14 days, statutory warranty of 24 months for consumers.
Every used Antminer that leaves our warehouse has already run at least one full load cycle on our own power supply before it reaches a customer. We are not a marketplace relisting devices from unknown sellers: the miners are physically in our warehouse in Bavaria, so we open, run and check them ourselves. The load test verifies that the stated hashrate range – for example 115-120 TH/s for the S19k Pro mix – is actually delivered per hashboard; fan and PSU function are checked under real load, and hashboards, connectors and case are inspected for damage or corrosion. If a hashboard fails the check, the unit is repaired or the affected board is removed from the batch before it is offered for sale.
New units come boxed from the factory with the current chip generation and the full 24-month statutory warranty for consumers. They are the better choice if you plan to run for more than two years, operate several units in parallel or pay a hosting tariff where every J/TH counts.
Buying an Antminer in Germany: customs, VAT, warranty, shipping
An Antminer 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. Shipping from our warehouse: Germany €19.90, EU €29.90 – both free from €1,000 order value. EU islands €49.00. Switzerland €40.00 (import duties are paid by the recipient).
| Criterion | Mining Technologies | Direct import from China | Private purchase (classifieds/eBay) |
|---|---|---|---|
| Customs / import VAT | None on top: stocked units are customs-cleared in Germany, ex-works models 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 | Stocked units 2–4 business days; ex-works models 10–14 days. | Several weeks (air or sea freight plus customs clearance). | By arrangement, often collection only. |
| Warranty | Statutory warranty: 24 months new, 12 months used for consumers. 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 | Used units: full load cycle with logged hashrate per hashboard. Stocked units are checked before dispatch. | 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. |
Electricity costs & profitability
Whether an Antminer pays off is decided by two numbers you control: the efficiency of the unit in joules per terahash (J/TH) and your electricity price per kilowatt-hour. The calculation is simple: J/TH × TH/s = watts, and watts × 24 h ÷ 1,000 × price per kWh = electricity cost per day. An S19j Pro at 3068W draws about 73.6 kWh a day – roughly €7.36 at 10 ct/kWh, €14.73 at 20 ct/kWh and €22.09 at 30 ct/kWh. An S21 at 2650W needs about 63.6 kWh a day for 151 TH/s instead of 104 TH/s.
Revenue, on the other hand, changes daily with Bitcoin price and network difficulty, so we do not publish fixed profit figures. As a rule of thumb, a low J/TH value only matters once your electricity price is high; at solar surplus or hosting tariffs the purchase price dominates. Run your own numbers with the Bitcoin mining calculator (revenue, break-even, ROI at current difficulty) and the electricity cost calculator (daily cost per model at your tariff) before you order.
Which Antminer for whom?
Four typical usage profiles, each with the matching models from our range:
- Beginners: a used, tested S19j Pro from €299 – low purchase price, proven firmware, easy pool setup (Buy Antminer S19, Buy used Antminer).
- PV surplus: efficiency matters less than purchase price when the power is free – S19j Pro or S19k Pro (23 J/TH) both fit a surplus-driven setup (Solar mining, Buy Antminer S19k Pro).
- Hosting: at hosting tariffs the newest generation pays – S21 (17.5 J/TH), S21+ (16.5 J/TH) or T21 (19 J/TH) (Mining server hosting, Buy Antminer S21, Buy Antminer T21).
- Farm / commercial: S21+ with 216 TH/s, hydro models up to 473 TH/s per unit, or the KS7 for Kaspa (Buy Antminer S19 XP, Buy Kaspa miner).
Frequently asked questions about buying an Antminer
How much does an Antminer cost?
The cheapest Antminer at Mining Technologies is the used, tested Antminer S19j Pro from €299 (from 10 units; single unit €349). The S19k Pro mix starts from €449, the new Antminer S21 costs €1.379 and the S21+ €2.149. All prices include 19% VAT.
Which Antminer is currently the cheapest way to start?
The Antminer S19j Pro (used, 104 TH/s, 29.5 J/TH) from €299 is the lowest entry price in the Antminer range. If you want better efficiency, take the S19k Pro at 23 J/TH from €449. Both are stocked in our warehouse in Bavaria.
Which Antminers ship immediately from German stock?
Right now 2 Antminer models sit in our warehouse in Bavaria: Antminer S19 J Pro and Antminer S19k Pro 115-120T Mix. They ship within 2–4 business days after payment. S21, S21+, L7, L9, KS7 and the hydro models are sourced directly ex works with a 10–14 day lead time; the T21 is available on request.
Do I pay customs or import VAT when buying an Antminer?
No. Stocked units are already customs-cleared in Germany, and for ex-works models we handle import and customs clearance. You pay the listed price incl. 19% VAT and receive an invoice showing VAT. No further duties apply within the EU; EU business customers with a valid VAT ID are invoiced under the reverse-charge scheme.
What warranty applies to new and used Antminers?
Statutory warranty applies: 24 months on new units and 12 months on used units for consumers. We do not add a voluntary guarantee on top. The exact scope is stated on each product page.
How are used Antminers tested before shipping?
Every used Antminer completes at least one full load cycle on our own power supply before it leaves our warehouse. We check that the stated hashrate is actually delivered per hashboard, verify fan and PSU function under real load and inspect hashboards, connectors and the case for damage or corrosion. If a hashboard fails, the unit is repaired or removed from the batch.
What does shipping an Antminer cost?
Germany €19.90, EU €29.90 – both free from €1,000 order value. EU islands €49.00. Switzerland €40.00 (import duties are paid by the recipient). Stocked units leave within 2–4 business days, insured, by parcel service or freight forwarder.
Is an Antminer worth it at German electricity prices?
That depends on your price per kWh, not on the model alone. An S19j Pro at 3068W uses about 74 kWh per day – at 30 ct/kWh that is roughly €22 a day. With solar surplus, cheap commercial power or as a heating replacement the numbers look different. Run your own scenario in our Bitcoin mining calculator before ordering.
