the fans are these - http://www.amazon.com/ARCTIC-USB-Powered-Portable-Cooling-Solution/dp/B003XN24GY/ref=pd_bxgy_pc_img_y
these arent laid out as well as the ankers, but I have a few of these 7-port ones and use them to power 5 each - http://www.amazon.com/dp/B003Z4G3I6/ref=pe_309540_26725410_item

Thanks the offer! The fan can be shipped, but the other USB hub is not shippable to my address either.

Found these on the German branch of Amazon:

Ankers are expensive!

Looks like this might be a more reasonable option (if it can power at least 5 units):

that hub will only power a max of 4 devices (and that might even be iffy), because it is a 5V 2A power adapter on it. you need to have 2.5VA per device. so for example if the adapter says 5V 3A then you can power 15VA worth of devices which = 15/2.5 = 6. you really have to be careful with the usb hubs cause you could potentially mess up a device or computer if overloaded. I bought some shitty ones off amazon that were 7-port and supposed to have a 2.5A adapter but they wouldnt power more than 3 devices. so best to go with something that have been tried with good success.
