I am currently running 4 gekkoscience newpacs and 3 2 2 pacs on a 10 port usb mining hub(sipolar). I am getting a respectable 380gh's from this mini rig. It's not a huge money maker but it pulls about 25 cents to 30 cents a day depending on what I mine it can pull a little more. For their size and energy they are the most efficient miners around and pretty robust for only 2 chips.
I would recommend them to anyone just looking to keep at least a little crypto rolling in everyday as I get BCH payouts everyday and am also getting namecoin every few days from this small operation.
This is what they look like just like their little brother the 2 pac but with better chips and the led is less bright which is nice as they look less like little disco lights (not complaining). They are a good little miner for starters of people like me who treat them like a faucet.
gekkoscience itself isnt carrying them right now I had to but mine on amazon, you can also get them on ebay but you may pay too much their.
I am not affiliated in any way with amazon ebay or gekkoscience.
I hope you enjoyed this lil piece on this miner.
