The A1246 is a 2021-generation miner at 38 J/TH efficiency. For comparison, the current Antminer S21 Pro runs at 15 J/TH — more than twice as efficient per terahash. At standard Australian electricity rates (~$0.30/kWh), the A1246 is not currently profitable. This unit is best suited to buyers with access to very low-cost electricity (under ~$0.08/kWh), bulk farm operators seeking lower-cost hardware per terahash, or buyers purchasing at a price that reflects its generation. Please assess your electricity cost before purchasing.
The A1246 remains relevant for specific use cases. Operators with sub-$0.08/kWh electricity — solar farms, hydro power, cheap industrial tariffs — can still extract value from the A1246's 90 TH/s. At a lower per-unit entry price than current-gen S21 hardware, it also suits bulk farm deployments where cost per terahash installed is the primary metric rather than efficiency. The integrated PSU, horizontal/vertical flexibility, and plug-and-play Ethernet setup make it practical to deploy at scale.
If you are a home miner or operate at standard AU electricity rates, the Canaan Avalon Q (18.6 J/TH, 1674W, AU-household compatible) or the Antminer S21 series (17.5 J/TH) are significantly better choices for your situation.

Bitcoin mining profitability depends on network difficulty, BTC price, electricity costs, and other market variables. MinerHub does not guarantee mining returns. The Canaan Avalon A1246 is a 2021-generation miner with 38 J/TH efficiency — significantly less efficient than current-generation hardware. At standard Australian electricity rates, this miner is currently operating at a loss based on publicly available profitability data. Buyers should carefully calculate their electricity cost and expected returns before purchasing. This unit is most suited to operations with sub-$0.08/kWh electricity access. Requires a dedicated 220–240V AC circuit — consult a licensed electrician if needed.
