MicroBT Whatsminer M21s is an SHA-256 algorithm mining equipment sold by Whatsminer. It is able to mine Bitcoin (BTC) with a maximum hashrate of 68TH/s for a power consumption of 3200W-3500W.

The MicroBT Whatsminer M21s technical specifications are as follows:

• M21S Whatsminer Bitcoin ASIC Miner running @ ~220V produces ~68TH/s
• M21S Whatsminer Bitcoin ASIC Miner
• Hashrate: 68TH/s (+/- 5%) (depends on cooling)
• Power Consumption: 60W/Thash = 56/Th @ 3200W-3500W per miner (+/- 10% )
• Controller: included
• Operating Temperature: 23F~104F / -5C~40C
• Size: 390mm x 150mm x 240mm / 15.3″ x 5.9″ x 9.

This device's noise is pretty normal, as most miners have a 60-80dB noise level. To better understand this, a noise level of 75 dB is equivalent to a vacuum cleaner's noise emission. The Whatsminer M21s can be used for mining at home as the noise level is optimal, but mining farms are more suitable. The noise is normal as a result of the two fans set for cooling.
