Just picked this up at Wal Mart. I wanted to use it as a charger for my JB3. It says on a few spots on this that it is not meant to recharge batteries. Anyone ever used this before for charging up your JB3 or anything else and run into problems? I have a few shows coming up where I won't be able to get home to charge up my JB3 and want it ready to go for show time. Any help would be great.
