Doesn't come with a power supply? REALLY? Yeah,  because I always want to hook my charger up to my truck battery... NOT!  My fault for not reading more carefully I guess. RETURNING!

It works great!  You don't need an AC adapter to power up this baby!

I'm sure it works as well as my other wine opener, but without an AC outlet in my house, what is the point?  At this price point, send an adapter along with it so it's usable.  I'm sending this baby back.

UPDATE:  The mfr contacted me about my review and nicely asked me to remove it as they explained that the product was supposed to be charged in the power base (or PC). I had no idea what this power base was. In hindsight, I suspect that the product was probably shipped without the power base, so I was left with an incompatible plug and a USB plug.  I wasn't about to plug it into my PC, so I sent it back. Had it come with the power base, I'm sure it would've worked fine.

Please note.  This comes without the AC Wall plug despite what the website says under the question and answer section.  Otherwise, it looks and functions as it should.

mine came with a broken power brick. I tested it with my multimeter and it has no current coming out. Now I have a $100 ornament. Can't find a replacement power supply to buy either.

Was disappointed to know that the power supply of the unit was 120v AC when on the descriptions indicated that it runs on both 120v or 230v AC. I had to get it converted for $120. Otherwise the item works perfectly. Please always let us know at what mains power the product works on!

5A version does not include AC cord, would be nice if the description warned about this;  Luckily it uses a stand ATX power supply cord and I had an extra around from an old PC.

Ignoring that minor negative seems to be a nice supply, outputs good voltage, no whine or hum, claims to be highly efficient, time will tell the rest.

I wished there was a standard connector size I prefer 2.5 inside for 12 and 2.1 for 5v, but no one seems to follow any standard, and it is the 2.1 it claims.

Seagate clearly wants you to believe this is not an AC powered hard drive. In all pictures there is no AC adapter, and you can't find it anywhere in the literature. Shame on them.

not come with org. power supply, also which sent to me is DC 12V, but the pre-amp using AC 12V!

After reading similar experiences of reviewers here, I can confirm this product does not work without a power supply when used to switch HD video between a generic Channel Master DVR and an XBox 360, unless the XBox is turned on.  Since the product does not include a power supply, this is a huge inconvenience.  I don't think I will be inclined to buy another IOGear product in the future.

I ordered this hub because I needed one with an external power supply. I saw that this hub has a power supply port so I ordered it. When I opened the package, there was no external power supply. That doesn't make very little sense to me. For what it is the hub works, but it should have included the adapter.

Delivered missing 18v power adapter.... I only gave it 1 star because I have no idea how it actually sounds.. wish I could get a power adapter shipped.

Did not ship with power supply or with any specifications as to how to acquire a suitable power supply.
Does not work with some USB devices - such as an external DVD player (apple DVD player on 2014 MBP). :(

Too bad Boss doesn't include an AC adapter in the box. Pay attention to the small letters. You will need an extra cable to plug it to the amp too.
