Canaan

Canaan develops Avalon-branded ASIC Bitcoin miners. Published Avalon information provides a concrete SHA256, air-cooled reference point, while public support and commerce routes could not be checked directly at the time of review.

Avalon is represented here as a SHA256 path

The Avalon A15 A1566 release identifies a SHA256/BTC machine. The retained Canaan record supports a Bitcoin SHA256 manufacturer comparison; it does not establish Bitmain-style multi-algorithm catalogue breadth.

On a first-party Canaan page checked in August 2026, several Avalon products appeared with purchase links. A listing is evidence of catalogue activity at capture time, not proof of present inventory, shipping eligibility or a completed order.

A named air-cooled specification frame

For the A1566, the published table states 185 TH/s at 25°C, 3,420 W at Tj75°C and 18.5 J/TH at Tj75°C, with stated tolerances. It also gives a 200–300 V supply range and a -5°C to 35°C working-temperature range.

Those figures are useful because they keep hash rate, power, efficiency and operating conditions together. Voltage and temperature ranges are deployment constraints, and the air-cooled design is not directly interchangeable with a hydro-cooled miner just because headline efficiency figures can be compared.

Current support details require order-time confirmation

Canaan's product, help and homepage routes returned access-denied responses when checked. That prevents a current direct confirmation of model details, firmware distribution, remote-control prerequisites, warranty terms and destination-specific supply conditions.

The access boundary is not evidence that Canaan lacks these services. It means a buyer should obtain the exact current manual, firmware path, warranty terms, stock position and delivery conditions from the relevant official sales channel before relying on them.

A SHA256 alternative to Bitmain's broader catalogue

Canaan is relevant when a named Avalon SHA256 machine's stated power, efficiency, voltage, temperature and air-cooling requirements fit the deployment. The A1566 is a released-model reference, not a claim that it is the newest, available or highest-performing Avalon unit.

Bitmain is the contrasting choice when the requirement begins with multi-algorithm coverage or directly retrievable manufacturer firmware and warranty procedures. The current research does not establish equivalent support or warranty arrangements between the two manufacturers.
