HP/Compaq ::Slim Travel Power Adapter

So while I was getting a blu-ray burner and HD upgrade for my DV5t, I got a promo advert in the mail from HP and it mentioned their Slim Travel Power Adapter (with USB charging port). I travel about 4000 miles by plane every 4-6 weeks, and I carry my Dv5t with me in a shoulder bag. After putting my laptop in a neoprene sleeve before putting it in the bag next to my paper file, there is not much room left in the bag for the power supply, wireless mouse, and misc cables, much less a bottle a water for the 4-hour plane trips.

On top of that, the charging port on my phone doesn't work anymore (I know, I need to change it, but I'm waiting for summer when I'm out of contract and can switch carriers and phones), but it still charges via the USB sync cable.

So the slim travel charger was looking pretty good - less space used in a very tight bag, and a way to charge my phone when my laptop is off. So I ordered it excitedly.

And I was quite let down.

The first issue I've had with it, is that although the transformer block it is slimmer in height that the one the that came with my laptop, it's just as long, and wider. At it's tallest, around the AC-in port, where it bulges out, it looks be just under a 1/4-inch in height savings. while being about 3/8th-inch wider and 1/8th-inch shorter (the long axis).
