Electricity cost in continuous operation

At 3610W of continuous draw this unit uses about 87 kWh per day and roughly 2599 kWh per month. That is about 260 € per month at 10 ct/kWh, 520 € at 20 ct/kWh and 780 € 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.

Frequently asked questions about the Antminer T21

How fast is the Antminer T21 delivered?

The Antminer T21 is currently not in stock; availability and lead time are on request — contact us by phone, WhatsApp or email and we will tell you the next delivery date.

What condition is the Antminer T21 in?

The Antminer T21 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 T21 use and what does that cost at 0.30 €/kWh?

The Antminer T21 draws about 3,610 W in continuous operation, i.e. roughly 86.6 kWh per day or 2,599 kWh per month. At 0.30 €/kWh that is about €25.99 per day and €780 per month. Whether that pays off depends on your tariff, not on the hashrate: at solar surplus or hosting rates the picture looks completely different, so run your own numbers in our mining calculator before ordering.
