About the 2PAC

Made right here in the USA, The 2pac uses 2 Bitmain 1384 chips (same as the Antminer S5) to get you about .33 J/GHs power consumption for each 2pac, which is more efficient than the Antminer S5 itself. You can adjust the frequency of the device in CGminer to get hash rates from 10GHs - 35GHS. You can also adjust the Vcore with a simple turn of a screw for better mining stability(zombie miners). I am more than happy to answer any question you have. These are perfect for people looking to get into bitcoin mining!

Lotto mining vs pool mining

You can go 1 of 2 routes with this device.  If you want small, consistent payouts every day, you should join a pool(slushpool, antpool, exc).  If you want a lotto miner (also called solo mining) which has the chance to win 12.5 bitcoins + transaction fees every 10 minutes, you should solo mine (solo.CKpool). If you want something in between, try bravos mining emporium (Tiny pool where you get 1 BTC if you hit a block)

What crypto can I mine with the 2pac?

The 2pac mines sha256 coins.  Coins include Bitcoin, BitcoinCash, Peercoin, and even the new litecoincash hardfork!


Due to bitcoin volatility and possible damage from overclocking, they're NO returns.

If you run over stock frequency, you NEED a small fan to cool them down.

This device uses VHs custom CGminer.  Message me for a download link. OS supported are Linux, mac, windows, and raspian.

The manufacturer does stability testing to ensure all miners are properly functional. This doesn't take more than a few hours. This does not mean they're used. The 2pacs look exactly like the ones in the listing photos

  • This is not a "2 pack" of miners. It is for (1) Gekkoscience 2pac USB miner. 2pac is the model name.
