Product Overview

The Bitmain Antminer AL1 15.6T is a commercial-grade Alephium (ALPH) ASIC miner from Bitmain, running the Blake3 algorithm at 15.6 terahashes per second. As Bitmain’s dedicated entry into the Alephium mining segment, the AL1 brings the same manufacturer’s engineering and support infrastructure familiar to Bitcoin miners into the growing Alephium ASIC category.

Alephium (ALPH) is a layer-1 blockchain combining UTXO-based smart contracts with a Proof of Less Work consensus mechanism using the Blake3 hashing algorithm. Since its mainnet launch in November 2021, Alephium has attracted significant miner interest, and the transition from GPU to dedicated ASIC hardware has accelerated as the network’s hash difficulty has grown. The AL1 15.6T is among the higher-hashrate air-cooled Alephium ASICs available, competing in the same segment as the IceRiver AL3 15T.

For South African operators, the Antminer AL1 15.6T offers commercial-scale Alephium mining from a proven manufacturer with an established firmware and support ecosystem. Its 1350W power draw is moderate for a commercial ASIC, making it accessible in terms of electrical infrastructure compared to larger SHA-256 miners.

Key Features

• 15.6 TH/s hashrate: High-output Alephium mining from Bitmain’s AL1 flagship, delivering strong ALPH pool contribution per deployed unit.
• ~1350W power consumption: At approximately 1350W, the AL1 15.6T is more power-efficient to run than most commercial Bitcoin ASICs, making it accessible for operators who want commercial-scale Alephium mining without requiring the highest-amperage electrical infrastructure.
• Blake3 algorithm: Dedicated to Alephium (ALPH) mining. Blake3 is distinct from SHA-256 (Bitcoin), kHeavyHash (Kaspa), and Blake2S/2B (Kadena/Handshake). The AL1 cannot be used for other algorithm networks.
• Air-cooled dual fan design: Industrial ASIC enclosure with dual high-speed fans. Standard rack deployment in a ventilated mining room — no specialist cooling required.
• Bitmain ecosystem: Standard Antminer firmware and management interface, familiar to operators running other Bitmain products. Pool configuration, monitoring, and firmware updates follow the standard Antminer workflow.
• Ethernet (RJ-45) connectivity: Wired network connection for pool communication. Web interface for setup and monitoring.
• Commercial-scale Alephium mining: While the Goldshell AL Box (360 GH/s) targets home miners, the AL1 15.6T’s 15.6 TH/s output is designed for operators wanting meaningful ALPH output at a commercial farming scale.

Power & Installation Notes

South Africa’s 230V/50Hz supply is within the Antminer AL1 15.6T’s 200–240V input range. No voltage converter is required.

At approximately 1350W, the AL1 15.6T is one of the lower-wattage commercial ASIC miners available. A single unit can be comfortably operated on a dedicated 16A circuit (safely loaded to ~2944W), with plenty of headroom. However, a dedicated circuit with a registered electrician installation is still recommended to ensure clean, uninterrupted power and to prevent circuit breaker issues from other loads on the same circuit.

Load shedding at 1.35 kW is relatively easy to manage. A standard 5kWh home battery can run the AL1 for over 3.7 hours, and a 10kWh battery would support over 7 hours of operation. This makes the AL1 one of the more load-shedding-friendly commercial ASIC miners for South African operators.

Ventilation: despite the lower power draw, the AL1’s dual fans still require clear airflow at both inlet and exhaust faces. Keep the mining environment below 40°C. Standard mining room ventilation (forced air extraction) is sufficient.

Electricity Cost Context — South Africa

Running the Antminer AL1 15.6T at 1350W continuously consumes approximately 32.4 kWh per day, or roughly 972 kWh per month. At R2.80/kWh (reference residential tariff — municipal rates vary), the estimated monthly electricity cost is approximately R2 722 per month.

Calculation: (1350 ÷ 1000) × 24 × 30 × R2.80 = ~R2 722/month.

At approximately R2 722 per month, the AL1 15.6T has a meaningfully lower electricity cost than commercial Bitcoin miners. This makes it one of the more accessible commercial ASIC options for South African operators at standard residential tariffs — though profitability depends entirely on ALPH price and network difficulty. This is an operating cost estimate only.

Ideal Use Cases

• Commercial Alephium mining farms: Operators wanting high per-unit ALPH output in a commercial form factor, using Bitmain’s established hardware and firmware ecosystem.
• Operators transitioning from GPU Alephium mining: The AL1 15.6T delivers far more ALPH per watt than equivalent GPU rigs, making it a compelling hardware upgrade for established Alephium miners.
• Lower-power-budget commercial operations: At 1350W, the AL1 requires less electrical infrastructure than Bitcoin or ETC commercial miners, opening it up to operators with more modest power budgets.
• Bitmain ecosystem operators: For operators who already run Bitmain hardware and want to add Alephium exposure using the same management tools and firmware processes they know.
• Comparison with IceRiver AL3: Operators comparing Bitmain and IceRiver Alephium hardware — the AL1 15.6T competes directly with the IceRiver AL3 15T in terms of hashrate and performance class.

Frequently Asked Questions

Does the Antminer AL1 15.6T work on South African power?
Yes. SA’s 230V/50Hz supply is within the AL1’s input range. A dedicated 16A circuit from a registered electrician is recommended for single-unit operation.

What is Alephium (ALPH) and why mine it?
Alephium is a proof-of-work blockchain using the Blake3 algorithm with UTXO-based smart contracts. ALPH is the native token. The network’s active development team, growing DeFi ecosystem, and PoW consensus have made it one of the more attractive newer mining targets. Profitability should be evaluated using current ALPH price and network difficulty data.

What mining pools work with the AL1 15.6T?
All standard Alephium Stratum-protocol pools are compatible. Popular options include Herominers, K1Pool, and Woolypooly. Configure via the Antminer web interface.

How does the AL1 15.6T compare to the IceRiver AL3 15T?
Both deliver approximately 15 TH/s on Blake3 at broadly similar efficiency. The AL1 is from Bitmain; the AL3 is from IceRiver. Choice depends on firmware preference, unit availability, and price. See: IceRiver AL3 15T Alephium.

Can I mine Bitcoin with the Antminer AL1?
No. The AL1 is a Blake3 ASIC and mines Alephium (ALPH) exclusively. For Bitcoin mining, see our Bitcoin ASIC miner range.
