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.

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.
