The CompacF is the most powerful USB miner ever made - that actually turns a profit in most cases. This rig includes active air cooling on each miner. Those miners can peak much higher wattage compared to the older version, the NewPac miner. It is up to 5 times more powerful than the NewPac miner as well. It is unlocked for overclocking (Voids warranty). It features a single 7nm technology BM1397 chip.
Wow, one of our fortunate customers struck gold by successfully mining a block and earning an incredible 6.25 BTC!
*Made in the USA.

** Some programming with Git is required on Linux to be able to mine on this new USB Miner. However, you can add to this kit our Raspberry Pi computer with Compac F preinstalled for easy beginner mining. Git file available here - https://github.com/kanoi/cgminer add to the line of code for mining "--gekko-compacf-freq 400"

UPDATE: I attached this device to the Mars Lander. The hash rate seems to fluctuate between 250 gh/s to 400 gh/s with at least one of the compac-f underperforming. I was instructed to keep it at 400 gh/s. I have to monitor the settings periodically because sometimes I catch these fans operating at 250 gh/s and another at 440 gh/s. I make sure to set it at 400 gh/s. I was expecting 1.2 th/s of hash rate with these fans (as promised) but the most I seem to get is ~850 gh/s. I do not want to be constantly monitoring these solo mining devices because I’m spending time on it when rewards are not guaranteed. I want to set it and forget it. This device fell short of my expectations. It also could have been manufactured better because the usb strip does not stay fully balanced when set on a table.

Little bit of fun
Nice little set up
Only problem is I thought I would be earning a little something from mining but from what I’ve read up on you only earn if you hit a block and that’s like winning the lottery but it’s a bit of fun for me expensive fun
But would like to find something to mine in the future that will pay small amounts into my crypto wallet
Would like to get the 909 miner as well at some point to ad too but a bit pricey for me at the moment in the future

Great Miners for Fun
So, if you buy these miners expecting to profit, don't. These are incredibly fun to play around with and lottery mine with. The fans are noisy so I wouldn't put them somewhere where you need silence but i don't mind the noise at my desk, personally. They work as intended. I don't have them overclocked and they still average close to 300 gh/s a piece. Setup was easy. Had them up and running in about 6 minutes total. Check them out if you want to play around with some usb miners but, again, don't expect a profit from these :)

Probably too expensive
Product is ok, price is probably too much considering also I had to pay 155€ of customs fee for something that's not for "production"
Fan are also a bit noisy.

caveat emptor
These compac F miners work. The issue is POWER. Even the provided 7-port hub stuggles to power the miners (in overclock state).
The Compac F requires a hub WAY OUT OF SPEC. Hence nearly impossible to find one.
My personal experience with the Compact F is a max clock range: 450-490 MHz. Not sure why I get varying results, but its a power thing.
The listed overclock of 400 will not get you to ~334 GH/s needed for a total (3 device) 1 TH/s.
If anyone is aware of a USB hub with over 3.1 amps per port - LET ME KNOW.
Love the fan even though I got it off Amazon I love the product and how the mining speed is

Awesome little miner
2nd review update to the first.
So far it's been running pretty well, stays at and around 350KH. Shows your hashrate, miners, on the pool. Haven't messed with it any further than just setting it up. Took roughly 5-10 minutes to set it up. Will definitely pick up some more whenever I can, will try to get something bigger and better lol. Everything gets shipped within a reasonable time and quickly arrives once shipped. Great place, very helpful.
Purchased Feb 2024, took a while to get to me; the power supply isn't powerful enough for this model, and the display stopped working in May 2025; the display just fell off today, Aug 8, 2025. If I had to do it all over again I would have bought a better model after researching the default power supply and the display sturdiness, plus I would have read more customer reviews online. When I purchase a new miner I'll do a better job before purchasing and it won't be this model.
