Anyone have one of the energizer external battery packs?

I saw this on woot

Energizer Universal 8000mAh Portable Battery Pack w/ AC Wall Adapter

8000mAh is pretty good, it could easily be used for a backup if you went away for a weekend and probably with very low usage get you through a week.

Does anyone have one of these? Does it cause any problems like the 3rd party chargers?
