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!

** 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.

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.
Set up was pretty easy, just followed the setup guide. I already had my etc wallet copied to clipboard at the start - thats a pr move. Also worked from my phone, not a desktop. Regardless, fun little miner that looks like a little clock on my desk.
