Black & Decker VPX Battery system for portable batteries?

dunno if there are better systems out there, or if this system will even work, but...

Black & Decker has a new Lithium-ion battery setup that can be used to power both their tools, and other electronics when coupled with an inverter that has USB and AC plugs.
I figure you can buy a couple of batteries and maybe get 30-60 min of battery life out of them, but then not only use them on the go, but at your work bench.

Here is the 2 prong AC/USB inverter setup:

This is the part that I don't know if it will work or not. I know some power bricks have 3 prongs, so you may need to buy a 2 prong adapter to hook it in.

Here is the battery:

I dont know how long it will actually keep your laptop running,
