I love the altoid tin thing, but I'm not as handy with the solder iron as I wish I were.

iPulse and Technet definitely looks like it has more juice, and sturdier, than the duracell packs I see locally. Can you two tell me how long it takes to recharge their internal battery? My only complaint is neither comes with an ac charger.. But that is true for alot of devices nowadays.

I like that the sunlinq and goal zero have (what I assume is) a car battery charger/adapter. The joos is also nice and surprisingly still just as compact as the "foldaway" models.
