Electricity cost in continuous operation
At 3068W of continuous draw this unit uses about 74 kWh per day and roughly 2209 kWh per month. That is about 221 € per month at 10 ct/kWh, 442 € at 20 ct/kWh and 663 € at 30 ct/kWh. Compare that figure with the daily revenue at current difficulty before ordering — your tariff, not the hashrate, decides profitability.

Setup and operation
Plan a dedicated, properly fused circuit, dust-free intake air and an unobstructed exhaust path. Air-cooled miners run at 70–75 dB and belong in a basement, garage, workshop or server room rather than a living space. Setup takes a few minutes: connect the network cable and enter pool and wallet in the web interface — on request we configure the unit before shipping.

How we check every used miner
- Origin: The units come from farm operation, where they ran under controlled conditions, and sit customs-cleared in our warehouse in Bavaria.
- Cleaning: Heat sinks and air paths are cleaned – dust is the most common cause of overheating.
- Load test: A full test run on our own power supply: hashrate of every hashboard, fans, temperatures, PSU and pool connection are checked and logged.
- Test video: On request we send a test video with the visible serial number and live hashrate before shipping.
- Firmware: Shipped with original Bitmain firmware or, on request, with Braiins OS+ pre-installed.
- Warranty: The statutory warranty applies; consumers also have a 14-day right of withdrawal.
Frequently asked questions about the Antminer S19 J Pro (Used)
Do I need a computer?
No. The miner connects to your router via LAN cable and is set up in a web browser – a smartphone, tablet or PC on the same network is enough. Open the IP address, enter your pool details, done. No computer needs to run permanently.
Will I get an invoice?
Yes, every order comes with an invoice showing VAT. Businesses in other EU countries with a valid VAT ID are invoiced under the reverse-charge procedure.
Can I pick it up?
Yes, pickup in Neustadt an der Aisch (Bavaria, Germany) by appointment – via "Book pickup" or WhatsApp.
What warranty applies?
Used devices come with the statutory warranty. Consumers also have a 14-day right of withdrawal. Details in our terms and withdrawal policy.

Shipping inside Germany is free for this unit; we also deliver to Austria, the rest of the EU and Switzerland.
What condition is the Antminer S19 J Pro (Used) in?
The Antminer S19 J Pro (Used) is a used unit. Before shipping it runs a full load cycle on our own power supply: we check the hashrate per hashboard, fan and PSU function under real load and inspect boards, connectors and case for damage or corrosion. Used miners show normal signs of use such as dust or light scratches on the case.
How much power does the Antminer S19 J Pro (Used) use and what does that cost at 0.30 €/kWh?
The Antminer S19 J Pro (Used) draws about 3,068 W in continuous operation, i.e. roughly 73.6 kWh per day or 2,209 kWh per month. At 0.30 €/kWh that is about €22.09 per day and €663 per month. Whether that pays off depends on your tariff, not on the hashrate: at solar surplus the picture looks completely different, so run your own numbers in our mining calculator before ordering.
