Buy Antminer S19 from €359 – Tested, German Stock

The S19 series at a glance

Bitmain's S19 series is the best-selling Bitcoin miner generation and today the standard entry point into home mining. Within the series the models differ mainly in efficiency: the S19j Pro delivers about 100 TH/s at 2,900 W (29.5 J/TH), the S19k Pro reaches 115–120 TH/s at roughly 2,645–2,760 W for about 23 J/TH, and the S19 XP goes lower still.

Because the series is so widespread, spare parts, PSUs, fans and firmware support are plentiful — a real advantage over niche models when a hashboard or PSU needs replacing after two years.

• Used Antminer S19j Pro from 319 € — tested, cleaned, logged hashrate
• New Antminer S19j Pro at 539 € — 100 TH/s at 2,900 W
• Antminer S19k Pro 115–120T Mix from 439 € — best price-to-efficiency ratio in the series
• Antminer Hydro water-cooled from 1,369 € — 230–473 TH/s for water-loop setups

S19j Pro or S19k Pro?

The S19j Pro is the cheaper purchase and pays off mainly at very low electricity costs, for example with surplus solar. The S19k Pro delivers more hashrate on less power per terahash, making it the better choice above roughly 15 ct/kWh — the price difference is usually recovered through running costs within months.

If unsure, start with one unit, measure real consumption at your own socket and scale from there. That is what we recommend to most customers.

Operation, firmware and tuning

All S19 models ship with Bitmain firmware and are configured to a pool through the web interface. Braiins OS can noticeably improve efficiency through undervolting because voltage and clock are tuned per chip. Please read our mining software notice first — changing firmware can affect any warranty claims you may have against the manufacturer.

For continuous operation: dust-free intake air, unobstructed exhaust, fan-speed monitoring and cleaning every six months. Units then easily outlast their payback period.

Models, prices and efficiency at a glance

Shipping, warehouse and delivery time

Stocked units ship within 2–4 business days from our warehouse in Bavaria, Germany. Because the hardware is already imported and cleared inside the EU, there is no import VAT, no customs paperwork and no waiting for air freight from Asia. Models sourced directly from the factory show their own delivery time on the product page.

We ship insured to Germany, Austria, Switzerland and the rest of the EU. Orders above 1,000 € ship free within Germany, and express shipping is available for stocked units.

Payment, invoice and warranty

You can pay by bank transfer, credit card, PayPal, Apple Pay or cryptocurrency. Every order comes with a proper invoice showing VAT. EU business customers with a valid VAT ID are invoiced at 0 % under the reverse-charge scheme, and we can switch your session to B2B mode with net prices.

New and used miners are covered by statutory warranty under EU law. Used units are tested, cleaned and shipped with a logged hashrate; the exact scope is stated on each product page.

Advice before you buy

We help you check electricity tariff, power connection, cooling, noise and realistic payback before you order — including when the honest answer is that a machine will not pay off at your kWh price. Send us your electricity cost and the planned location and we will run the numbers with you.
