Product and specifications
The Bitmain Antminer S21 XP is the most energy-efficient air-cooled Bitcoin miner currently on the market. With a hashrate of 270 TH/s on the SHA-256 algorithm and a power efficiency of just 13.5 J/TH, the S21 XP sets a new industry benchmark for ASIC mining. It runs at 3,645W from the wall and ships with the PSU (power supply) included.
USP’s
At Antminer Distribution Europe we ship the S21 XP directly from the Netherlands, so EU customers pay no import duties, no customs fees and avoid border delays. Every unit includes the PSU and comes with up to 2 years of warranty instead of the standard 180 days. Orders are shipped within 7 business days across the EU and worldwide.
Use case
The S21 XP is built for serious Bitcoin miners: professional mining farms scaling multi-unit deployments, as well as individual miners with access to dedicated power infrastructure and low-cost electricity. Thanks to its 13.5 J/TH efficiency, the S21 XP offers one of the shortest paybacks per watt among air-cooled miners available in 2026.
Why choose the Antminer S21 XP?
Comparison to previous generation
The S21 XP improves energy efficiency by 10 percent over the Antminer S21 Pro (15 J/TH) and by 37 percent over the older S19 XP (21.5 J/TH). For the same 270 TH/s hashrate, you spend less on electricity every single day. In a 24/7 mining setup, that difference compounds fast and directly increases ROI.
Electricity cost calculation
At an electricity rate of 0.10 EUR per kWh, the S21 XP costs approximately 8.75 EUR per day or 262 EUR per month in power. At 0.15 EUR per kWh, that rises to 13.12 EUR per day or 393 EUR per month. Your local rate is the single most important variable for your net return, so always run the numbers for your own setup before purchasing.
Who is the S21 XP for?
Professional mining farms benefit from the 13.5 J/TH efficiency at scale, where every joule saved translates into meaningful operational savings. Serious individual miners with a dedicated circuit (220V, minimum 20A), proper ventilation and access to sub-0.12 EUR/kWh electricity also get strong returns. Home miners without these conditions should consider smaller, quieter models first.
