Get a new camera
Hi,
I've got a photoflash cap bank of my own, and so far I've found that the charging circuit of the camera is the best/easiest charger to find and use. If you threw yours away, or can't use it anymore for some reason, I'd suggest trying to find a new one. The only problem is when charging large amounts of caps (it takes about 15 minutes to fully charge 20 of the caps in my bank with one charger... I don't do that anymore).
