Specifications
The hash rate of the Whatsminer M21S is 56T, which gives it an edge over the M21 model, and the physical size is 155 x 240 x 390mm with a weight of 7.1kg. The size dimension makes the device less bulky to handle and also helps conserve space in mining farms. 
The M21s come with a P5-12-2200-V1 power supply to produce an output of DC 12.8V 172A, and the 10A socket in the mining farm works well. 
The power supply comes with an aluminum rack, which protects the wires on the connector side. It is used as a handle for ease of usage.
This miner works with a power efficiency of 0.06j/Gh, and it has two 12038 cooling fans, one for blowing air and one for release of air, and the fan power is 12V 2.8A, just like its older model.

Algorithm
The Whatsminer M21s mines with the SHA-256 algorithm can produce up to 40 coins, but the top coins are Bitcoin(BTC) and Bitcoin Cash(BCH). With an average hash rate of 56Th/s, it uses 3360W of power. 

The board is an Ethernet interface, TF card slot, IP button, reset button, and status indicator on the control. But the most impressive is the fact that the MAC address is attached to the control board for convenience when looking for the device’s IP address. This feature aligns with Whatsminer’s pledge to produce miners that are easy to use for everyone.
