Description
The Canaan Avalon Nano 3S is a compact desktop Bitcoin miner built by Canaan Inc., a NASDAQ-listed company with over a decade of ASIC mining hardware experience. It produces up to 6 TH/s of SHA-256 hashrate at a maximum of 140 watts, making it one of the most efficient and affordable desktop miners available in 2026. The Avalon Nano 3S runs quietly between 29 and 36 dB depending on mode, which is comparable to a library or a quiet home office. Solo Satoshi is an authorized Canaan distributor and ships every order same-day from Houston, Texas with a 1-year Canaan manufacturer’s warranty.
The Nano 3S is an upgrade over the original Avalon Nano 3, delivering 50% more hashrate at the same 140-watt power draw thanks to a new generation of 4-nanometer ASIC chips across 12 dies. It connects via Wi-Fi or Ethernet, includes the power supply in the box, and can be configured through the Avalon Family app or a browser-based interface. The device also generates warmth from its 140-watt power draw, so it can act as a supplemental desk or room heater if placed close to you.
Avalon Nano 3S vs Nano 3: What Changed
The Avalon Nano 3S replaced the original Nano 3 in March 2025 with a significant performance upgrade. Both models share the same 140-watt power envelope, but the Nano 3S uses next-generation 4-nanometer chips that push hashrate from 4 TH/s to 6 TH/s. That is a 50% increase in mining performance with no increase in electricity cost.

If you are considering a Nano 3 from a reseller, be aware that the Nano 3S delivers 50% more hashrate for the same electricity cost. Solo Satoshi carries only the current Nano 3S model. Learn more about the complete Canaan Avalon home series in our full guide.
Avalon Nano 3S Performance Specifications
The Avalon Nano 3S operates in three selectable power modes. Independent testing and community reports confirm the following real-world performance across Low, Medium, and High settings. You can estimate how each mode affects your daily mining returns with the Solo Satoshi Bitcoin Mining Profitability Calculator.
| Mode | Hashrate | Power | Efficiency | Noise | Heat Output | Est. Monthly Electricity* |
|---|---|---|---|---|---|---|
| Low | ~3.1 TH/s | ~66W | ~21.2 J/TH | ~29 dB | ~225 BTU/h | ~$7.60 |
| Medium | ~4.8 TH/s | ~104W | ~21.6 J/TH | ~32 dB | ~355 BTU/h | ~$12.00 |
| High | ~6.0 TH/s | ~140W | ~23.3 J/TH | ~36 dB | ~478 BTU/h | ~$16.13 |
*Electricity estimates based on $0.16/kWh, the U.S. national average. Heat output calculated from electrical load at 1W = 3.412 BTU/h. Results vary with ambient temperature and firmware version.
Low mode is ideal for nighttime or quiet environments. High mode maximizes hashrate during the day. The three-mode system gives you flexibility to run the Nano 3S around the clock without disrupting your household.
At current network difficulty and a hashprice of approximately $0.034/TH/day per our calculator, the Nano 3S on High mode earns roughly 200 to 300 satoshis per day through pool mining, or approximately $0.20 worth of BTC daily before electricity. Solo mining offers the chance at the full 3.125 BTC block reward instead. Run the numbers for your electricity rate with the Solo Satoshi Bitcoin Mining Profitability Calculator.

How the Avalon Nano 3S Compares to Other Home Miners
The Avalon Nano 3S sits between ultra-low-power open-source miners and higher-output desktop ASIC units. The comparison below shows how it stacks up against the most popular home Bitcoin miners available at Solo Satoshi in 2026.
| Miner | Hashrate | Power | Efficiency | Noise | Open Source | Price |
|---|---|---|---|---|---|---|
| Bitaxe Gamma 602 | 1.2 TH/s | ~17W | ~15 J/TH | ~35 dB | Yes | ~$130 |
| Bitaxe Duo 650 | 1.63 TH/s | ~25W | ~15 J/TH | ~35 dB | Yes | ~$130 |
| Bitaxe GT 801 | 2.15 TH/s | ~39W | ~18 J/TH | ~40 dB | Yes | ~$200 |
| Avalon Nano 3S | 6 TH/s | ~140W | ~23.3 J/TH | 29–36 dB | No | $299 |
| NerdQaxe++ | 6+ TH/s | ~100W | ~15.65 J/TH | ~45 dB | Yes | ~$382 |
| Avalon Mini 3 | 37.5 TH/s | ~1,100W | ~21.3 J/TH | 33–55 dB | No | $1,129 |
| Avalon Q | 90 TH/s | ~1,674W | ~18.6 J/TH | 45–65 dB | No | $1,799 |
The Nano 3S delivers the highest hashrate of any miner under $300 in this lineup while maintaining noise levels suitable for a living room or bedroom. The NerdQaxe++ matches its hashrate with better efficiency but costs more at ~$382. The Bitaxe Gamma 602 and Bitaxe Duo 650 are more efficient per terahash but produce far less total hashrate. For buyers who want maximum home mining power, the Avalon Q delivers 90 TH/s with three tunable power modes and doubles as a space heater producing over 5,700 BTU/h. The right choice depends on whether you want maximum hashrate per dollar or maximum efficiency per watt. Read our 2026 mini Bitcoin miner guide for a deeper comparison.
“The Nano 3S is the strongest value under $300 in our entire lineup. At 6 terahashes, it sits in the same hashrate tier where we have seen customers win full Bitcoin blocks, including a $347,000 payout from a Solo Satoshi customer running similar hashrate on Public Pool in October 2025.” — Matt, Founder and CEO, Solo Satoshi
Compatible Mining Pools and Solo Mining
The Avalon Nano 3S works with any Stratum-compatible Bitcoin mining pool. You are not locked into a single pool. Popular options include Solo CKPool for true solo mining, Public Pool for self-hosted solo setups, Ocean Mining for transparent pool mining, and F2Pool which comes pre-configured on the QR card included in the box. You can also point the Nano 3S at your own Bitcoin node running on a Start9 Server One or an Umbrel node for maximum sovereignty.
Solo mining with the Nano 3S means you compete for the full 3.125 BTC block reward rather than splitting it with a pool. The odds are long for any single desktop miner, but the home mining community has proven it is possible. Since July 2024, Solo Satoshi customers and the broader open-source mining community have confirmed five solo block wins using compact home miners, with total payouts exceeding $1 million in BTC. Learn more about how solo mining works and the documented wins in our block finds article and our Bitcoin pool mining guide.
What Is in the Avalon Nano 3S Box

Firmware Updates and Troubleshooting Tips
The Avalon Nano 3S ships with stable factory firmware, but Canaan periodically releases updates that improve Wi-Fi stability, hashrate consistency, and overall performance. Updating firmware is recommended shortly after unboxing and can be done through the Avalon Family app (iOS and Android) or the built-in web interface on your local network.
To update via the app, open the Avalon Family app, select your miner from the device list, and tap the firmware update option if one is available. The process takes approximately two minutes. To update via the web interface, navigate to your miner’s IP address in a browser, locate the firmware section, and upload the latest file from Canaan’s official GitHub repository.
If your Nano 3S loses Wi-Fi after a restart, make sure your network name (SSID) and password do not contain special characters such as quotes, ampersands, or angle brackets. The Nano 3S connects on 2.4 GHz Wi-Fi only, so confirm your router is broadcasting on that band. If the connection still fails, hold the function button on the back of the unit for 10 seconds to factory reset and re-enter your network credentials through the Avalon Family app.
For persistent issues, the included power adapter should remain cool during normal operation. If the adapter feels excessively warm, ensure it has adequate ventilation and is not covered or enclosed. Canaan’s after-sale support team can be reached through canaan.io/support, and Solo Satoshi’s customer support team is available for setup assistance via our contact page.

Ideal Use Cases
The Avalon Nano 3S is built for everyday spaces and everyday users. It is quiet enough for apartments, condos, bedrooms, and home offices where noise matters. The three power modes let you run it at 29 dB overnight and increase hashrate during the day. At 140 watts on High mode, the device also generates enough warmth to take the edge off a small desk area during cooler months, though it is not a replacement for a dedicated room heater.
The Nano 3S is an excellent choice for first-time miners who want a turnkey device with no assembly required, Bitcoin enthusiasts who want to participate in securing the network from home, educators and students learning how SHA-256 mining and proof-of-work function in practice, and gift-givers looking for a functional and unique Bitcoin-related gift. If you are looking for an open-source alternative that you can overclock and modify, explore the Bitaxe lineup instead.
