Hmm, I just saw Addonics's new Power+ USB 2.0 hub: http://www.addonics.com/products/host_cont...%2Busb2_hub.asp
Very interesting, at first I was confused why they're making such a big deal about a standard powered USB hub, but then I saw it's *really* high power. Makes sense for them to release such a product -- they've been advertising ALL of their Pocket series of portable drives (HDD, optical) as being able to run off bus power, including USB bus (in addition to 1394, PC Card). But if you look it up, their various DVD/CD Pocket drives have been eating up more and more max power from one model to the next, up to like 7.5W (at 5V, so at least 1.5A) -- I've been wondering what USB bus power can supply that And of course, my earlier posts in this thread have detailed my borderline power consumption problems with their Pocket ExDrive enclosure when used with various different HDDs.
Anyways, this does beg the question, is this new hub unique, or do some other USB hubs/ports on the market already supply around this level of bus power? If so, are they technically illegal outside spec, and could it possibly damage some USB peripherals that really can't handle much more than 0.5A current?
Also note that Addonics is offering an optional, even higher-power AC/DC adapter, and a car power adapter (12VDC -> 5VDC I guess?) for the hub. The default AC/DC adapter's "only" rated for 3A, and each of the 4 ports on the hub is capped up to 2A max. So if you use a really power hungry peripheral up to 2A on one port, that leaves little power for the other 3 ports?
Thus I'm guessing the high-power adapter would supply like 8A to be able to give 2A to each port (and that's why they say it would be able to run 4 Pocket drives simultaneously)? Man, we're dealing with FireWire level power now
Can't wait to get this hub...
