Antminer S21 Pro: price, profit per day & hosting
The S21 Pro is the best-value efficient Bitcoin miner right now: 220–245 TH/s at about 14.5 J/TH, for much less than an S21 XP. It's one of our best sellers, including bulk orders.
We carry it used from California, new from our USA stock, and as the newer S21 Pro+ batch. Pick the hashrate you want; power scales with it.

7.75¢/kWh is our metered air hosting rate (7.5¢ for 20+ machines). Revenue is what the hashrate earns per day at current difficulty and coin price; it changes daily. Payback is price divided by today’s profit and ignores future difficulty changes.
Good fit if…
- You want strong efficiency at the lowest price per TH
- You're buying several machines (ask about 20+ unit pricing)
- You want a used unit with a 7-day DOA that ships from the USA
Worth knowing
- Needs 200–240 V power and a hosting site or a well-ventilated space; it's loud.
- Used units are tested twice and carry a 7-day DOA. New units carry the manufacturer's warranty.
Antminer S21 Pro questions
What's the difference between 220T, 234T and 245T?
Same machine, different hashboards binned at different speeds. Power scales with hashrate, so efficiency stays about 14.5 J/TH. Higher hashrate earns more per day and costs more upfront.
Is a used S21 Pro a good buy?
Used units are tested before storage and again before they ship, and carry a 7-day DOA that starts the day the unit arrives. They're the cheapest way into a 14.5 J/TH machine.
Do you offer bulk pricing?
Yes, from about 20 units. Message us on Telegram or WhatsApp at +1 (951) 598-1515 or email sales@805mining.com.
