Does anyone know of a power pack with folding blade plug?

[graffixnyc]

I've been looking to get an external usb power pack for use with my phone and tablet when I dont have power. I have seen the trent and others but you need to plus them in with a wire to recharge them. I also saw someone(I should of asked them who made it) that had one that has a folding blade plug so you can just plug the whole thing into the wall to recharge it instead of using a wire. Does anyone know what companies makes these types? I found one for a musicplayer but it seems rather low capacity so I'm looking for something with higher capacity with a folding blade. Thanks!
I've googled usb power pack folding blade, usb power pack blade etc..

How much capacity?

iGo makes one but it's only 1800mah. It has the folding prongs. It also works as a wall charger.

Zagg makes the ZaggSparq. Seems a little pricey but looks good.

That Zagg one looks nice but a big price tag. Rather buy another extended battery for that price.
