Canaan Avalon Nano 3S official owner reference

Official exact reference: Canaan lists the air-cooled Avalon Nano 3S at 6 TH/s and 140 W maximum, with 28 V device input, 50/60 Hz on the adapter listing, -5–30°C operation, and 33–40 dB.

The manufacturer lists 205 × 115 × 58.5 mm net dimensions and approximately 0.86 kg net weight.

Efficiency remains source-dependent

One exact Canaan listing headline prints 29 J/TH, while the 6 TH/s and 140 W maximum figures produce a different simple ratio; another official Nano 3S listing omits efficiency. This reference therefore does not publish a normalized 23.3 or 29 J/TH value without an exact operating-mode definition.

Adapter and connector gate

28 V is device-side DC input, not wall-side mains. Match the exact regional adapter label, plug, cable, connector revision, output voltage, current, and wattage. Physical USB-C fit does not establish electrical or protocol compatibility, and Nano 3 adapters must not be assumed interchangeable with Nano 3S hardware.

Firmware and app routing

Confirm Nano 3S, its connector revision, and installed version before updating. Do not transfer Nano 3, Mini 3, Avalon Q, or industrial Avalon packages.

• Check the Home firmware/version record.
• Use the exact Home update workflow.
• Select only an exact Nano 3S resource from Canaan.

Known boundaries: no normalized efficiency, wall-side adapter voltage, ASIC model/count, controller identity, adapter interchangeability, tuning, economics, price, or lifecycle status is asserted.
