Avalon Nano 3S

The Avalon Nano 3S is Canaan's small desk miner. Sellers state about 6 TH/s at up to 140 W, roughly five times a Bitaxe Gamma's hashrate, in a finished case with an included power adapter and Wi-Fi. At 140 W it gives off about as much warmth as a small personal heater, so it doubles as a desk or foot warmer.

Best for: Someone who wants more hashrate than a Bitaxe in a finished, quiet box, for a desk, office or bedroom.

• Color: black and white are usually the same price.
• Solo or pool: it can do either. Pick in its settings (see our solo vs pool guide).
• Prices are before shipping and sales tax.

Seller-stated 6 TH/s (+/- 5%) at up to 140 W. Running cost assumes full power 24/7; heater miners usually cycle with a thermostat, so real use is often lower.

Sellers state about 140 W, roughly 1,226 kWh a year if it runs 24/7. At $0.10, $0.15 and $0.25 per kWh that's about $123, $184 and $307 a year.

Almost all the electricity a miner uses comes out as heat, like an electric space heater. At full power that's about 140 W, or roughly 478 BTU per hour. How heater miners work.

Usually not all of it, and nothing is guaranteed. Pointed at a mining pool, it earns small, steady amounts of bitcoin that can offset part of the power bill. How much depends on Bitcoin's price, the network's total hashrate and your electricity rate, and all three change. Pointed at solo mining, it's a lottery ticket for a whole block.
