Compare 21energy Ofen 3 Base vs MicroBT WhatsMiner M7AS+

The MicroBT WhatsMiner M7AS+ delivers superior daily profit of $7.40 versus $-0.31 from the 21energy Ofen 3 Base. With current electricity rates, the MicroBT WhatsMiner M7AS+ provides better return on investment through more efficient power consumption relative to its mining output. The MicroBT WhatsMiner M7AS+ consumes 7500W versus 1000W for the 21energy Ofen 3 Base, resulting in $12.48 higher daily electricity expenses. This power difference becomes particularly important for large-scale mining operations where every watt counts toward overall facility efficiency and cooling requirements.

Release timeline shows the 21energy Ofen 3 Base launched in October 2026 while the MicroBT WhatsMiner M7AS+ entered the market in November 2026. Newer miners typically incorporate improved chip architecture and manufacturing processes, leading to better efficiency and performance characteristics. Physical dimensions comparison reveals the 21energy Ofen 3 Base measures 900 x 320 x 140mm while the MicroBT WhatsMiner M7AS+ has dimensions of 483 x 86 x 663mm. Size considerations directly impact rack density, shipping costs, and facility space requirements for mining operations. Weight specifications show the 21energy Ofen 3 Base at 17000g compared to 29000g for the MicroBT WhatsMiner M7AS+. Heavier units often indicate more robust construction and heat dissipation components but may require stronger mounting solutions and increase shipping expenses. Acoustic performance differs with the 21energy Ofen 3 Base operating at 35db versus 35db for the MicroBT WhatsMiner M7AS+. Noise levels significantly impact placement options, with quieter units suitable for residential or office environments while louder miners require dedicated facilities with proper sound isolation. Humidity specifications indicate the 21energy Ofen 3 Base operates within 5 - 95 % conditions compared to 5 - 85 % for the MicroBT WhatsMiner M7AS+. Better humidity tolerance enables deployment in more diverse geographic locations and reduces the need for expensive climate control systems in mining facilities.
