Generally speaking, I am unsure how anyone can say that a charger for a battery pack is "poop" and expect anyone to respect their opinion about the product.

Also generally speaking I would most likely say that the pack sold on Ebay is going to be a cheap variant of those sold everywhere else. A battery is simply a storage device and all of them are going to be the same, with the exceptions being their connections and wire quality. With that said, check around and buy the one you like.
