GekkoScience Bitcoin SHA256 USB Stick Miner 90GH+ NEWPAC BM1387 BTC

Out of stock


Manufactured in the USA by legendary GekkoScience (Sidehack). Currently the most efficient USB miner ever manufactured. The NEWPAC Compac features 2 Bitmain BM1387 chips (this is the same chip as in the Bitmain S5). The stock clock setting is 100MHz for 23GH. The possible frequency values range from 100MHz to 600MHz, which generates speeds from 23GH to 130GH. Please make sure you provide extra cooling (table fan, usb fan, etc) when running the miner because these can get very hot (especially when running over 100 MHz frequency).


Stock speed: 23 GH 
High Speed: 90 GH+ (Higher speed requires usb port above spec) 
Completely silent operation
2 x Bitmain BM1387 chips
Made in USA
