Having recently been involved in a 999 emergency call and challenged by lack of battery power, I have just been looking at Power Hit's disposable charger. Whilst its seems useful as an emergency back up power pack, it provides no clue as to its shelf life. It also comes in a sealed package which makes me wonder if it might be an air / zinc based battery so the package state is important. Their web site is totally uninformative. Has any one any clues about how long these devices can sit in one's rucsac? (And remain useful!)
