We are not retail.
Nice, I have six 2pacs on a kdata 10 port 12V hub running ok. A zombie here and there still. Sipolar has been more consistent though. Waiting for newpacs to arrive here this coming week and hopefully soon the GS hub sidehack has been talking about. I think I drool more at night dreaming about these lately.

Hey Phil, what do you think about this hub? I've never seen it before and just now found it on Amazon. It's a 12-port USB 3.0 hub made by "coolgear". You must find your own AC power adapter, with a 3-pin plug, and it's pretty beefy looking. Perhaps it should be for its $114.95 USD price, and keep in mind, you will need to purchase a compatible power supply (unless you're Phil and have one just laying around). Anyway, let me know what you guys think!  Wink

Coolgear Industrial 12-Port USB 3.0 Powered Hub for PC-MAC DIN-RAIL Mount https://www.amazon.com/dp/B00P1RMET2/ref=cm_sw_r_cp_apa_myG8BbWHYFTJC

over priced and the ports are too close.

this one

https://www.ebay.com/itm/Sipolar-10-Port-USB-2-0-Powered-Hub-with-power-supply-5V-20-Amp-2A-per-port/352409900554?

10 ports 81 with shipping   so 8.10 a port  comes with psu.

a 250 freq clock  seems to use 11 watts at the wall  so the psu rates for 120 watts x .8 = 96

this means  you can do 8 sticks. Maybe

so far it does 3 sticks 2x newpacs and 1x 2pac perfectly with 2 fans.

I know I can fit  6 sticks with the spacing and 6 sticks should pull 66 watts which a 120 watt brick should handle.

your listing has 12 ports for 112 + a power supply will cost $$  at least 28 or maybe 32

so 12 ports are close to  12 dollars each and they are close to one another  so you need  2x usb to 1 x usb wires.

So far at the current pricing the sipolar looks good.

What we don't know is will it do   more then 3 sticks at 250 freq.  I get a fourth stick tomorrow that will help testing more.

To be clear klintay has sold eyeboot gear listed below

49 port = well made
19 port usb 2 = well made
19 port usb 3 = well made
10 port usb 3 = well made also named sipolar

Above all good.

Below not good..

Asicminer 49 port not made by klintay as far as I know and not well made.

So they were badly made. Pull that fuse and put in a 20 amp. As they tended to melt.

Asicminer built them.  I owned 128 sticks and could run about 40 on three hubs for a total of 120 sticks.

You can pull 1.1 amps on a port if you run about 15 sticks on the hub.

As always, your posts are very useful.  Thanks!

Sifting through all of the garbage out there and finally may have found one or two decent options for a hub. Not sure if klintay has/had anything to do with designing or making these, but he's really the only one I know making USB hubs specifically for mining (like these new ones I just found). The company was once SiPolar (which I'm fairly certain is/was owned by klintay), but seems to be using the name ICONE now. Anyway, both hubs are basically the same, except one is twice the power of the other. Prices listed below are/were the current prices in USD at time of this post, and include any shipping charges..

I recently acquired a Block Erupter 49 port USB 2.0 Hub Rev 2.00 (Red board) to use with my 2PAC and Terminus pod that I purchased from sidehack as well as some miscellaneous USB miners.  Finding information about these hubs are more elusive than I imagined.  Does anyone know of a support thread or other resource to post my questions to?

1) Who was the OEM/Primary distributor for these back in the day?  Asicminer? Eyeboot?  Someone else?
2) The unit has what appears to be a 25A automotive style fuse.  Does that mean that is fused for 12V 25A?
3) 25A would only allow 500mA per port with only 500mA extra to handle startup surge.  Does that seem right?
4) Is it likely that the traces would allow more power than 500 mA if the board's total power rating is not exceeded?

More goal is to run more 2PAC and other USB miners as the price is right and I acquire them.  I should have asked what fuse was on the board since I have read about other 49 port Block Erupter hubs having 50 or 70A fuses.  Does it seem likely that I can run a few higher-power usb devices like 2PAC or Moonlanders on this board?

I really appreciate your time and information!  Do you think that the Version 1 Red Boards would safely accept a 50A fuse?

i don't really think so, but i don't know what condition your unit it is in...just be careful

yes it should do, you could even change the fuse if you wanted to.....for the new 50A boards you can check them out here:

I got the Plugable 7 port 60 hub powering my RPI along with 3 2pacs running @ 200MHz with a small USB fan, any idea how many kWh I'm looking at?
Well the maximum the hub can supply is 60 watts so running @ full power for 1 hour = 0.060kWh.... aka, 60Wh
Someone flunk simple math? Wink

Thanks for the information!  Will the board allow for higher wattage per port if the total power drawn is below the 25A?

Let me have a think....Red board is one of the originals from first batch! Thus is uses the 25A as 0.5 amps per port was all the block erupters needed.
Newer boards have 50A built in fuse now.

Curmudgeonly hardware guy
I'd talk to your buddy who already has a working setup. The biggest difference between 2Pacs and Moonlanders is the required USB driver, but hardware good for one should be good for the other.

ok so struggling here a little bit

i bought one of these under the advisement of a buddy- he is running 10 moonlanders in one of these and said for me to get one to run my five 2pacs

https://www.amazon.com/USB-2-0-Hub-Aluminum-Mounting/dp/B076HLY2L9

but its not working

is it the hUb?? or is it something else going on??  its a powered mining hub, so why isnt it working
my guess is that not enough power being supplied??  

I have the 2pacs running just fine if i plug direct to usb on computer - but as soon as i use hub- forget it- nothing working and no miners mining

please help

Yesterday I added a 5V/2A (phone charger?) power supply to it which seems to work fine.
...
But when I plug in a second 2Pac this second one becomes active and the first one seems to drop in speed and the blue/white led stops flashing.

Your power supply is too weak. At the very best, you are going to get 10W out of that power supply, but likely much lower. One 2PAC can pull over 10W depending on your settings.

Mornin',

A few years ago I bought one of these cheap usb hubs:

https://www.ebay.com/itm/7-Port-USB-Hub-AC-Power-Adapter-ON-OFF-Switch-High-Speed-For-PC-Laptop-MAC-/232257938944

Yesterday I added a 5V/2A (phone charger?) power supply to it which seems to work fine.

When I plug my 2Pac in it it's up to 7 times faster than plugged into the RasPi3 directly.

But when I plug in a second 2Pac this second one becomes active and the first one seems to drop in speed and the blue/white led stops flashing.

Can these cheap hubs be modded with some wiring to have more power on the ports?

Those were 10 single chip Compacs running at default freq, the hub was powered by a 7amp brick that I had left over from the failed U3's disaster of Bitmain's. The fan had it's own small brick for power as did the RPi. The weakest link was the RPi which would randomly lockup and have to reboot.


Unfortunately, even though I had surge protectors on all of my gear, the building was struck by lightning while I was at work. The surge took out all five of my desktop PC's and monitors. The low voltage afterwards that my 2 S7-LN's, these 10 Compacs, and 10 2PACS were connected too caused the main 110v A/C line to melt and destroyed most of the gear including the ceiling fan in the room which turned out to be on the same circuit.
