Nerdaxe Ultra 500Gh/s 12W Bitcoin Solo Miner

The unit is rated at approximately 500 GH/s of Bitcoin-mining hashrate, while consuming only about 12 W of power under standard conditions.

It is designed for the SHA-256 algorithm and used for mining Bitcoin (BTC) in a solo configuration or small pool.

With ~500 GH/s at ~12 W, this corresponds to an efficiency of about 24 J/TH (12 W / 0.5 TH) – extremely low power for this hashrate tier. According to some specs: ~20 J/TH.

The unit runs on low voltage (e.g., 5 V DC in some specs for open-source version) or a typical home plug via included adapter, making it easier to plug into standard outlets. Some listings: 5 V, Imax ~3 A.

Yes because of its extremely low wattage and compact form-factor, it is especially suited for hobby-miners, home setups, or users who want a quiet, low-maintenance “mini” Bitcoin miner. However, the probability of hitting a Bitcoin block solo remains extremely small given network difficulty.
