Canaan Avalon Mini 3 37.5TH Bitcoin Home Miner

Description

The Canaan Avalon Mini 3 is a 37.5 TH/s SHA-256 Bitcoin miner with an integrated power supply, baseboard heater form factor, and app-controlled performance modes. It draws up to 800W, operates between 33 and 55 dB, and ships from Solo Satoshi in Houston, Texas with same-day fulfillment and a 1-year Canaan manufacturer warranty.

Solo Satoshi is an authorized Canaan distributor. Price includes the miner, power cable, USB Wi-Fi dongle, and region-specific power adaptor.

Canaan Avalon Mini 3 Specs

Customer reviews confirm the Mini 3 consistently exceeds its rated hashrate. One verified buyer reported sustained output above 40 TH/s at stock settings.

Five Operating Modes

The Avalon Mini 3 includes five selectable modes controlled through the Avalon Family App (iOS and Android). Each mode adjusts hashrate, power draw, fan speed, and noise to match your situation.

The thermostat-controlled Heater Mode is what separates the Avalon Mini 3 from traditional ASIC miners. Set your target temperature in the app, and the miner manages itself. No manual adjustments, no external smart plugs required.

Electricity Cost and Mining Revenue

Understanding cost before you buy is critical. Here are the monthly numbers at common US electricity rates.

At current network difficulty, pool mining revenue for 37.5 TH/s fluctuates with Bitcoin’s price and hashprice. The honest trade-off: at typical US electricity rates, pool mining alone may not cover the power bill in all market conditions.

The economics shift when you account for hashrate heating. If you already run an electric space heater during colder months, your electricity cost is a heating expense you were going to pay anyway. The Bitcoin you earn becomes a bonus on top of heat you needed. Over a 5-month heating season at $0.12/kWh, you would spend approximately $345 running the Mini 3 at full power. A standard 800W electric space heater would cost the same $345 and produce zero Bitcoin. Plug your specific rate into the Bitcoin mining profitability calculator to model your setup.

How the Avalon Mini 3 Compares

The Mini 3 sits between the entry-level Avalon Nano 3S and the full-power Avalon Q in Canaan’s home mining lineup.

The Nano 3S is ideal for desk-side warmth and Bitcoin education under $300. The Avalon Q is for customers who want the most hashrate and heat output from a single unit and have a dedicated 20A circuit. The Mini 3 hits the sweet spot: enough hashrate to produce meaningful Bitcoin, enough heat to replace a standard room heater, and it runs on a normal household outlet without special wiring.

For a full breakdown of all three models including setup instructions, pool configuration, and mode-by-mode testing data, read the Canaan Avalon Home Series Complete Mining Guide.

Setup in Under 10 Minutes

The Avalon Mini 3 ships fully assembled with an integrated power supply. No external PSU, no wiring, no soldering.

1. Insert the included USB Wi-Fi dongle into the rear USB port.
2. Plug the power cable into the bottom power port. Lock the safety buckle into place.
3. Flip the rear power switch to ON. The screen displays “Hi” and a Bluetooth icon.
4. Download the Avalon Family App. Create an Avalon account if you don’t have one.
5. Pair the miner via Bluetooth in the app. Select your home Wi-Fi network.
6. Enter your mining pool URL, worker name, and wallet address. Or configure for solo mining with Public Pool or your own Bitcoin full node.
7. Select your preferred operating mode. The miner starts hashing immediately.

For hardwired Ethernet, connect a USB-to-Ethernet adapter (TP-Link UE306 is a commonly compatible option, sold separately) instead of the Wi-Fi dongle. Both connection types support the “set it and forget it” philosophy: once configured, the Mini 3 runs unattended.

Built for Residential Environments

Noise Levels in Context

At 33 dB in lower modes, the Avalon Mini 3 is quieter than a whisper. At 55 dB on full power, it is roughly the volume of a normal conversation. Night Mode specifically reduces fan speed for bedroom use. For comparison, industrial ASIC miners typically operate at 75 dB and above, which is unsuitable for any living space.

Safety Features

Tip-over protection automatically cuts power if the unit is knocked over. Heater Mode includes thermostat cycling to prevent overheating. The 6063T5 aluminum alloy enclosure manages heat dissipation across the full baseboard surface area. Place the Mini 3 on a flat, hard surface with clearance around the air intake and exhaust, away from curtains, bedding, or anything flammable.

Room Coverage

At 800W (~2,730 BTU/h), the Mini 3 serves as primary heat for a room of approximately 80 square feet using the standard 10 watts per square foot guideline. In Eco Mode at ~500W, it works as supplemental heat for larger spaces. According to Canaan’s specifications, the unit can raise a 10 cubic meter room from 15°C (59°F) to 21°C (70°F) in about 10 minutes at full power.

Solo Mining and Pool Mining

The Avalon Mini 3 is compatible with any standard Stratum mining pool. Popular options include Braiins Pool, Ocean, ViaBTC, F2Pool, and Antpool. For solo mining, it works with Solo CKPool and Public Pool.

At 37.5 TH/s, the Mini 3 offers a meaningfully better chance at finding a solo block compared to smaller home miners. The potential reward is the full 3.125 BTC block subsidy plus all transaction fees.

What are the full specs of the Canaan Avalon Mini 3?+

The Avalon Mini 3 delivers 37.5 TH/s of SHA-256 hashrate using 66 advanced 4nm ASIC chips at 800W of power consumption. Efficiency sits at 21.3 J/TH. Dimensions are 760 x 104 x 214 mm, and the unit weighs 8.35 kg. Noise levels range from 33 to 55 dB depending on the selected power mode. It operates on universal input voltage from 110V to 240V AC at 50/60 Hz, includes both Wi-Fi and Ethernet connectivity, and runs safely in ambient temperatures between -5°C and 40°C with humidity under 90%. It ships with an integrated power supply and is ready to plug in out of the box.

Does the Avalon Mini 3 really work as a space heater?+

Yes. Every watt the Avalon Mini 3 consumes is converted into heat, which makes it functionally identical to an 800W electric space heater. The difference is that this device also produces Bitcoin hashrate while it heats your room. A traditional space heater converts electricity into heat and nothing else. The Avalon Mini 3 converts electricity into heat plus Bitcoin earnings. Same watts, more value. At full power the unit can warm a small to medium room in about 10 minutes. This concept is known as hashrate heating, and it is one of the fastest growing trends in the Bitcoin home mining space.

What power modes does the Avalon Mini 3 offer?+

The Mini 3 has multiple operating modes designed for different scenarios. Mining Mode pushes full hashrate at 800W for maximum Bitcoin output. Eco Mode runs around 500W for daytime warmth in smaller rooms with lower power draw. Super Mode delivers the full 800W heater experience with peak performance. Night Mode reduces noise and prioritizes a calmer sound profile for bedrooms. Heater Mode allows you to set a target room temperature through the app, and the miner cycles on and off to maintain that temperature automatically. This flexibility makes the Avalon Mini 3 a true dual-purpose appliance that adapts to your daily schedule.

How do I set up the Canaan Avalon Mini 3?+

Setup takes about 10 minutes. Insert the included Wi-Fi receiver into the USB port before powering on the device. Plug the power cable into the power port on the bottom of the unit, make sure the safety buckle locks in place, and flip the main switch to ON. The screen will display "Hi" and show a Bluetooth symbol. Download the Avalon Family App, register for an Avalon account, and pair the device via Bluetooth. From there, select your Wi-Fi network, enter your pool credentials or solo mining details, and the miner begins hashing. For a full walkthrough of the Canaan Avalon home lineup, read the Canaan Avalon Home Series complete mining guide.

Can I use the Avalon Mini 3 for solo mining?+

Yes. The Avalon Mini 3 supports both pool mining and solo mining configurations. You can point it to your own Bitcoin full node or connect it to a solo mining pool like Public Pool. At 37.5 TH/s, your odds of hitting a full block reward are much stronger than smaller home miners, though still rare compared to industrial hardware. The potential payoff is the full 3.125 BTC block reward plus transaction fees. For a deeper breakdown of how solo mining works and what to expect, read the complete guide on what a solo miner is and how solo Bitcoin mining works.

How loud is the Avalon Mini 3 and can I run it in a bedroom?+

The Avalon Mini 3 operates between 33 and 55 dB depending on the power mode. At the lower modes, 33 dB is comparable to a whisper or quiet library. Even at full power, 55 dB is roughly the volume of a normal conversation. Night Mode specifically reduces noise output for bedroom use while still providing warmth and mining. Compared to industrial ASIC miners that hit 75 dB and above, the Mini 3 is designed from the ground up for residential environments, apartments, bedrooms, offices, and living rooms.

Does the Avalon Mini 3 come with a power supply?+

Yes. The Avalon Mini 3 ships with an integrated power supply and a power cable suited for Northe America. The universal 110V to 240V input means the Mini 3 works with standard household outlets worldwide without the need for special wiring or a separate PSU purchase.

What is the difference between the Avalon Mini 3 and the Avalon Nano 3S?+

The Avalon Nano 3S is the entry-level home miner in the Canaan Avalon lineup. It delivers 6 TH/s at 140W in a compact desktop form factor, ideal for gentle warmth and an introduction to Bitcoin mining. The Avalon Mini 3 is a significant step up with 37.5 TH/s at 800W in a baseboard heater form factor, providing over six times the hashrate and substantially more heat output. The Mini 3 also includes Ethernet support, more power modes, thermostat-controlled heating, and a larger 4nm chip array. For buyers who want serious hashrate without the headache of industrial gear, the Mini 3 fills the gap perfectly. Compare all three models in the Bitcoin home miners category.

How much heat does the Avalon Mini 3 produce?+

At full power the Mini 3 draws 800W, and since virtually all of that energy converts to thermal output, it produces approximately 2,730 BTU/h of heat using the standard 1W = 3.412 BTU/h conversion. That is enough to comfortably warm a small to medium-sized room. A common rule of thumb is 10 watts per square foot, so on Super Mode the Mini 3 can serve as primary heat for roughly 80 square feet. In Eco Mode at around 500W, it works well as supplemental warmth for larger spaces or as background heating during milder conditions.

What does the Avalon Mini 3 warranty cover?+

The Canaan Avalon Mini 3 includes a 360-day manufacturer warranty counted from the factory shipping date. If an eligible hardware defect occurs during that period, it qualifies for Canaan's standard warranty service process.

Can I connect multiple Avalon Mini 3 units together?+

Yes. You can run multiple Avalon Mini 3 units in the same home by pointing them all to the same Bitcoin wallet address and mining pool. Each unit operates independently with its own power connection and network setup through the Avalon Family App, but your hashrate and earnings stack across all devices. For example, running three units gives you 112.5 TH/s of combined hashrate while heating multiple rooms simultaneously. This approach lets you scale your Bitcoin home mining setup room by room without any special hardware or wiring between the units.

Does the Avalon Mini 3 support Wi-Fi and Ethernet?+

The Avalon Mini 3 supports both Wi-Fi and Ethernet connectivity. Wi-Fi is the default connection method, set up through the included USB Wi-Fi receiver and the Avalon Family App. For users who prefer a more stable, hardwired connection, Ethernet is possible through a USB to Ethernet adapter sold separately. A common compatible option is the TP-Link UE306, though compatibility can vary by adapter. Either way, the device is designed to be "set it and forget it" once configured. Choose based on your home network setup and how close the miner sits to your router.

Is the Avalon Mini 3 safe to run unattended in my home?+

The Avalon Mini 3 is engineered for residential environments and includes a tip-over protection feature that automatically shuts the unit down if it is knocked over. The thermostat-controlled Heater Mode cycles the miner on and off to maintain a target temperature, preventing overheating. Operating temperature range is rated between -5°C and 40°C. As with any appliance that produces heat, place the Mini 3 on a flat surface with adequate clearance around the air intake and exhaust, away from curtains, bedding, or flammable materials.

How much electricity does the Avalon Mini 3 use per month?+

At full 800W draw running 24 hours a day, the Avalon Mini 3 consumes approximately 576 kWh per month. At a US average electricity rate of $0.12/kWh, that comes to about $69 per month. In Eco Mode at roughly 500W, monthly consumption drops to around 360 kWh, or about $43 per month at the same rate. If you are already running a space heater during the colder months, the Avalon Mini 3 replaces that cost while also earning Bitcoin. Use the Bitcoin mining power consumption calculator to plug in your specific electricity rate and see your projected costs and earnings.

What mining pools work with the Avalon Mini 3?+

The Avalon Mini 3 is compatible with any standard Stratum mining pool. Popular choices include F2Pool, ViaBTC, Braiins Pool, Ocean, and Antpool. For solo mining, it works with Solo CKPool and Public Pool. You enter your pool URL, worker name, and optional password directly through the Avalon Family App or the web management interface. For an in-depth comparison of pool types and how they distribute rewards, check out the guide on understanding mining pools.

What coins can I mine with the Avalon Mini 3?+

The Avalon Mini 3 runs the SHA-256 hashing algorithm, which means it can mine Bitcoin (BTC) as its primary coin. It is also compatible with other SHA-256 based cryptocurrencies including Bitcoin Cash (BCH) and Bitcoin SV (BSV). Pool configuration determines which coin you mine. Most home miners use it for Bitcoin given the asset's value, network security contribution, and long-term potential.

Is the Avalon Mini 3 profitable?+

Profitability depends on your electricity cost, the current Bitcoin price, and network difficulty. At standard US electricity rates, the Mini 3's daily mining revenue may be close to or slightly below the daily electricity cost during certain market conditions. However, the real value calculation changes when you factor in hashrate heating. If you were already going to pay for an electric space heater during winter months, that electricity cost is not a mining expense. It is a heating expense you were already going to incur, and the Bitcoin earned becomes a bonus. Over time, with Bitcoin's historical appreciation, sats stacked today may be worth significantly more in the future. To model your specific scenario, run the numbers in the Bitcoin mining profitability calculator.

Can I control the Avalon Mini 3 from my phone?+

Yes. The Avalon Family App gives you full control of the Avalon Mini 3 from your smartphone. Through the app you can switch between Mining Mode, Eco Mode, Super Mode, and Night Mode. You can configure your mining pool, set the thermostat for Heater Mode, adjust display settings, toggle the night light, turn the screen on or off, and monitor real-time hashrate, power consumption, and IP address. The app connects to the miner over your local Wi-Fi network using Bluetooth for initial pairing.

Why should I buy the Avalon Mini 3 from Solo Satoshi?+

Solo Satoshi is an authorized Canaan distributor based in Houston, Texas, with over 40,000 devices shipped worldwide. When you buy from Solo Satoshi, you receive authentic hardware direct from Canaan, same-day shipping from a US warehouse, and access to a dedicated support team that actually runs these miners at home.

You are not just buying a miner. You are joining a home mining community.

How does the Avalon Mini 3 support Bitcoin decentralization?+

Every Avalon Mini 3 running in a home represents independent hashrate that no corporation controls. As Bitcoin mining has become increasingly concentrated among large industrial operations, home miners play a critical role in distributing hashpower across thousands of locations and jurisdictions worldwide. The Mini 3 makes this practical by being quiet enough for living spaces, efficient enough for residential power, and simple enough for anyone to operate. When you run a home miner, you are actively contributing to Bitcoin's security model and supporting the decentralized network that makes Bitcoin valuable. The Heat Punks movement is built on exactly this idea, turning home heating into a tool for network security and individual sovereignty.

Can I solo mine Bitcoin with the Avalon Mini 3?+

Yes. The Avalon Mini 3 supports solo mining right out of the box. You can point it to a solo mining pool like Public Pool, or connect it directly to your own Bitcoin full node for the most sovereign setup possible. At 37.5 TH/s, the Mini 3 gives you a significantly better chance at finding a block compared to smaller home miners like the Avalon Nano 3S or a Bitaxe. The reward for hitting a block solo is the full 3.125 BTC plus all transaction fees, with nothing split among pool participants. The odds are still long against the total network hashrate, but every valid hash is a real chance, and home miners have hit solo blocks before. Use the Bitcoin solo odds calculator to check your estimated time to find a block at 37.5 TH/s, and read the full breakdown on what a solo miner is to understand the strategy and expectations before you start.
