10 Best Antminer 2025 in the United States

The Antminer S21+ 235T is a high-powered Bitcoin mining machine designed to offer strong performance with a hash rate of 235 terahashes per second (TH/s). It uses 3878 watts of power, which translates to an energy efficiency of about 16.5 watts per terahash, meaning it provides good mining output while managing electricity costs fairly well. This miner includes an air-cooling system to keep the device running at optimal temperature, but as with most powerful miners, it produces a significant amount of noise, so it may not be ideal for quiet environments or residential use.

The BITMAIN Antminer S21 XP 270T is designed for serious cryptocurrency miners looking for high performance. It offers a strong hash rate of 270 terahashes per second (TH/s), which means it can process a large number of Bitcoin and similar SHA256-based currency transactions quickly. However, this power comes with significant electricity use—running at 3645 watts—which is quite high and will impact your electricity costs.

The Bitmain Antminer L9 by TheTechWave is a strong choice for those interested in mining cryptocurrencies like Litecoin and Dogecoin using the scrypt algorithm. It offers a solid hash rate of 17 GH/s, which means it processes mining tasks quite efficiently. However, this comes with a relatively high power consumption of 3400 watts, requiring a 220V power supply, so it won’t work with standard residential outlets in many countries without special wiring.
