Product Overview

The IceRiver AL2 Lite is a dedicated Blake3 algorithm ASIC miner designed for Alephium (ALPH) mining. Delivering 2 TH/s at a relatively modest power draw, the AL2 Lite is positioned as an accessible entry point into dedicated Alephium ASIC mining — suitable for home miners and small-scale operations who want purpose-built ALPH hardware without the infrastructure demands of larger units.

Alephium uses the Blake3 algorithm and its blockDAG architecture to deliver a unique combination of proof-of-work security and smart contract functionality. Dedicated ASIC hardware like the AL2 Lite significantly outperforms GPU mining for ALPH in terms of both hashrate and energy efficiency, making it the practical choice for serious Alephium miners. IceRiver is one of the primary manufacturers offering purpose-built Alephium ASIC miners.

For South African ALPH miners, the AL2 Lite’s compact form factor and modest power draw make it particularly attractive. Its wattage falls within a range where it can potentially be sustained through load shedding on a home inverter system — a meaningful advantage given South Africa’s ongoing power supply challenges. It can also function as part of a diversified mining portfolio alongside Kaspa (KAS) miners or other algorithm-specific hardware.

Key Features

• 2 TH/s Blake3 Hashrate (±5%): Dedicated Alephium mining at a practical entry-level hashrate. Suitable for solo contributions to ALPH mining pools without requiring industrial-scale infrastructure.
• Low Power Consumption: The AL2 Lite’s modest power draw makes it one of the more energy-accessible Alephium ASIC options, manageable on residential electrical circuits with appropriate planning.
• Dedicated Blake3 ASIC: Purpose-built for the Blake3 algorithm used by Alephium. Far more efficient than GPU-based ALPH mining, making it the preferred choice for dedicated ALPH operations in 2024 and beyond.
• Compact Form Factor: The AL2 Lite’s smaller chassis is suitable for home mining room shelves, compact rack setups, or dedicated mining spaces where physical footprint is a consideration.
• Air-Cooled Design: High-speed fans manage thermal output. Requires adequate ventilation in its operating environment but does not need specialised cooling infrastructure.
• Standard Ethernet Interface: RJ45 connectivity with a web-based management interface for pool configuration, monitoring, and firmware management.
• Load-Shedding Friendly: At its modest power draw, the AL2 Lite is potentially supportable on a well-sized home inverter and battery bank — a key advantage for South African home miners.

Power & Installation Notes

The IceRiver AL2 Lite has a modest power draw relative to larger ASIC miners. In South Africa, the specific circuit requirements will depend on the confirmed wattage — contact us at time of purchase for exact electrical specifications.

As a general guideline for smaller Blake3 ALPH miners: a dedicated 16A circuit with appropriate wiring is typically sufficient. South Africa’s 230V / 50Hz grid supply is within the AL2 Lite’s 200–240V input specification — no transformer is required. Ensure wiring complies with SANS 10142; engage a registered electrician if you are installing a new dedicated circuit.

Load shedding manageability is one of the AL2 Lite’s key strengths for South African miners. At a lower wattage than many competing ASIC miners, the AL2 Lite can potentially be sustained through load shedding on a standard home inverter and battery system. A 2–3 kVA inverter with a 5 kWh battery should provide several hours of runtime at full load. Always verify your inverter’s continuous output rating (not just peak) before using it to power mining equipment.

Ensure adequate airflow around the unit. Position in a space where fan exhaust is directed away from the intake and ambient temperatures remain below 40°C for stable operation.

Electricity Cost Context — South Africa

The exact monthly electricity operating cost for the AL2 Lite depends on its confirmed wattage. Using Eskom’s approximate residential reference tariff of R2.80/kWh, the formula is:

(Watts ÷ 1,000) × 24 × 30 × 2.80 = Monthly cost (ZAR)

As an example, a miner drawing 600W would cost approximately (600 ÷ 1,000) × 24 × 30 × 2.80 = R1,209.60 per month to run continuously. Confirm the actual wattage with us at time of purchase for an accurate cost estimate. This is an operating cost estimate only — not a profitability projection. Actual electricity tariffs vary by municipality and supply category.

The AL2 Lite’s lower wattage relative to larger ASIC miners makes it one of the more affordable Alephium mining options from an electricity cost perspective, supporting its viability for small-scale and home operations.

Ideal Use Cases

• Home Alephium mining: The AL2 Lite’s compact form factor and low power draw make it well-suited for South African home miners who want dedicated ALPH hardware without industrial-grade electrical infrastructure or significant noise impact on living spaces.
• Entry point into dedicated Blake3 ASIC mining: For miners transitioning from GPU-based ALPH mining, the AL2 Lite offers an accessible pathway to more efficient, purpose-built ASIC performance without a large capital outlay.
• Diversified mining portfolios: Operators who already run Kaspa (KAS) miners or other algorithm-specific ASICs can add the AL2 Lite to their setup for ALPH exposure with minimal additional infrastructure requirements.
• Load-shedding-resilient operations: At its modest power level, the AL2 Lite is potentially supportable on a home inverter — making it a practical choice for South African miners who want continued uptime through power outages.

Frequently Asked Questions

Does the IceRiver AL2 Lite work on South African power?
Yes. South Africa’s 230V / 50Hz supply is within the unit’s 200–240V / 50–60Hz input range. No transformer is required. A dedicated circuit is recommended — contact us to confirm exact electrical requirements at time of purchase.

What coins does the AL2 Lite mine?
The AL2 Lite mines Alephium (ALPH) using the Blake3 algorithm. Alephium is the primary Blake3 proof-of-work coin, combining a blockDAG structure with EVM-compatible smart contracts for a unique layer-1 blockchain.

Which pool should I use for ALPH mining?
Major Alephium pools include Herominers, 2Miners, and K1Pool. Configure the pool’s Blake3/ALPH stratum URL in the AL2 Lite’s web interface and enter your ALPH wallet address as the worker ID. Most pools use PPLNS reward distribution.

Can the AL2 Lite run during load shedding?
Potentially yes — with appropriate inverter and battery sizing. At its modest wattage, the AL2 Lite is one of the more inverter-friendly ASIC miners available. A 2–3 kVA inverter with a 5 kWh battery bank should sustain it through a standard 2-hour Stage 2 outage. Confirm your inverter’s continuous output capacity before relying on it for mining equipment.

How does the AL2 Lite compare to the IceRiver AL3 15T?
The IceRiver AL3 15T (15 TH/s) delivers significantly more hashrate than the AL2 Lite (2 TH/s), at correspondingly higher power consumption and cost. The AL2 Lite is the accessible entry point; the AL3 is for operators who want maximum ALPH output from a single unit and have the infrastructure to support it.
