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. 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.
What a nice GUI based mining tool for experiments!
At first I was a bit scared about this little jewel... 1MH/s is a lot of work for small ESP32 biprocessor.
Instead, the hashrate was quite constant. The configuration was easy, the use was a breeze, and the three screens on the display show a lot of information.
Very useful the choice to hold the maximum worked difficulty between restarts! Also, opening the browser on the Internet IP address of the miner shows a panel with all the miners present on your private network (on the photo there is only one miner, but I long to have more soon...).
All in all an interesting and mature product, that is pushing me to add more solo miners on my network.

Wow
Love this little thing. Makes for great stocking suffers. I will be honest here and say dyor! This miner doesn't compare to the other miners on this site.
This miner is 40% the speed of other's I have purchased for less that look identical, but use a faster chip package. But, this is a legit miner, with the proper software and case, and you can see it working on the public web site. It is Waugh-2 in the photo below. Waugh-3 is there little Lotto Miner, which is just for fun. No assembly is required, it comes in a nice plastic case well protected, along with QR code cards you can scan for instructions if you are not familiar with how to set them up. In addition, they include a little surprise that is a nice touch. All in all, they are a legit company, and none of these are for serious miners anyway.
