Product Overview

The Canaan Avalon Mini 3 is a compact, home-optimised Bitcoin (BTC) SHA-256 ASIC miner from Canaan — one of the original ASIC mining hardware manufacturers and creators of the Avalon miner brand. With a hashrate of 37.5 TH/s and a self-contained design that includes an integrated cooling system, the Avalon Mini 3 is designed specifically for home miners who want to mine Bitcoin in a quieter, more convenient form factor than traditional industrial ASIC units.

The Avalon Mini 3 is part of Canaan’s Mini series — compact, all-in-one Bitcoin miners built around the principle that home mining should be accessible and low-hassle. Unlike industrial miners that ship as bare boards requiring external PSUs and rack mounting, the Avalon Mini 3 is a self-contained unit with an integrated power supply, built-in controller, and a cooling system designed to be quieter than large-format industrial ASICs.

For South African home miners, the Avalon Mini 3 represents an attractive entry point into Bitcoin mining without the electrical infrastructure, noise management, and technical complexity associated with commercial-grade units. At 800W, it can run from a standard household socket, making it genuinely practical for home deployment.

Key Features

• 37.5 TH/s hashrate: Competitive SHA-256 output for a home-scale Bitcoin miner. Provides meaningful pool contribution from a single compact unit.
• ~800W integrated power consumption: Self-contained with an integrated PSU. At 800W, it can be run from a standard South African 16A household socket without dedicated electrical infrastructure.
• Integrated all-in-one design: The Avalon Mini 3 includes the miner, PSU, and built-in controller in a single compact enclosure — no separate power supply or rack mounting required.
• SHA-256d algorithm: Mines Bitcoin (BTC) as the primary target. Also compatible with Bitcoin Cash (BCH) and Bitcoin SV (BSV) on SHA-256d networks.
• Quieter operation for home use: Canaan’s Mini series is engineered for lower noise levels than industrial ASIC miners, making it more practical for use in home garages, studies, or dedicated mining rooms where noise management is a concern.
• Canaan’s established mining hardware ecosystem: Canaan is one of the three major global ASIC manufacturers alongside Bitmain and MicroBT. The Avalon platform has an established community, firmware support base, and clear product roadmap.
• Wi-Fi or Ethernet connectivity: Some Avalon Mini configurations support both Wi-Fi and wired Ethernet connection — confirm at time of purchase. Web interface for pool configuration and monitoring.

Power & Installation Notes

South Africa’s 230V/50Hz supply is within the Avalon Mini 3’s universal input range. No voltage adaptor is required. The integrated PSU handles SA’s voltage natively.

At approximately 800W, the Avalon Mini 3 can safely operate from a standard South African 16A household socket (rated 3680W, safely loaded to ~2944W). A single unit places minimal strain on standard home circuits and requires no dedicated electrical work. For multiple units on the same circuit, total load should remain below the circuit’s safe continuous rating.

Load shedding at 800W is manageable with standard home battery systems. A 5kWh home battery can support the Avalon Mini 3 for approximately 6.25 hours, and a 10kWh battery for over 12 hours — sufficient to cover extended load shedding periods on any schedule. This is one of the more load-shedding-resilient Bitcoin ASIC miners available for home use in South Africa.

The Avalon Mini 3’s integrated cooling system is designed for quieter operation than industrial ASICs. Ensure the unit has clear air circulation around it and is not placed in an enclosed space. Normal room ventilation is typically sufficient for single-unit home operation below 35°C ambient.

Electricity Cost Context — South Africa

Running the Avalon Mini 3 at 800W continuously consumes approximately 19.2 kWh per day, or roughly 576 kWh per month. At R2.80/kWh (reference residential tariff — municipal rates vary), the estimated monthly electricity cost is approximately R1 613 per month.

Calculation: (800 ÷ 1000) × 24 × 30 × R2.80 = ~R1 613/month.

At approximately R1 613 per month, the Avalon Mini 3 has a very accessible electricity cost profile for a Bitcoin ASIC miner. This makes it one of the more cost-effective options for South African home Bitcoin miners who want to mine BTC without significant ongoing electricity expense. Profitability depends on current BTC price and network difficulty — evaluate using a mining calculator before purchase. This is a cost estimate only.

Ideal Use Cases

• Home Bitcoin miners: The Avalon Mini 3’s compact all-in-one design, manageable power draw, and reduced noise make it ideal for South African home miners who want to mine BTC from a spare room, garage, or home office.
• First-time Bitcoin ASIC miners: An accessible entry point into Bitcoin mining without the complexity of separate PSU, rack mounting, and high-amperage electrical work associated with industrial ASICs.
• Load-shedding-conscious miners: At 800W, standard home battery backup is practical. One of the few Bitcoin ASICs where you can realistically run through South African load shedding without a generator.
• Canaan/Avalon ecosystem participants: For miners who prefer Canaan’s Avalon platform over Bitmain or MicroBT, the Mini 3 offers an entry into the Avalon ecosystem with a clear upgrade path to the larger Avalon Q and Avalon Nano series.
• Small-scale parallel deployments: Multiple Avalon Mini 3 units can be run from standard household circuits — making it feasible to run 2–3 units in a home without dedicated electrical infrastructure, for those who want to scale modestly.

Frequently Asked Questions

Does the Avalon Mini 3 work on South African power?
Yes. The universal input handles SA’s 230V/50Hz natively with no adaptor needed. At 800W, it runs from a standard 16A household socket.

How does the Avalon Mini 3 compare to other home Bitcoin miners?
The Mini 3 sits between small low-power home devices (like the Avalon Nano 3S at 6 TH/s) and commercial ASICs. At 37.5 TH/s and 800W, it offers more meaningful Bitcoin pool contribution than nano-scale devices while remaining home-friendly. See also the Avalon Nano 3S for an ultra-compact comparison.

What Bitcoin pools are compatible with the Avalon Mini 3?
All major SHA-256 Bitcoin pools: Foundry USA Pool, AntPool, F2Pool, ViaBTC, Braiins Pool. The Avalon Mini 3 uses standard Stratum protocol for pool connection.

How loud is the Avalon Mini 3 compared to commercial ASICs?
The Mini 3 is engineered for quieter operation than industrial Antminer or Whatsminer units. Exact noise levels should be confirmed at purchase, but it is designed to be home-friendly rather than data-centre class in terms of noise output.

Does the Avalon Mini 3 include a power supply?
Yes — the Avalon Mini 3 is an all-in-one design with an integrated PSU. No separate power supply is required, which simplifies setup compared to many commercial ASICs.
