content: That's called a battery charge circuit... the choice of which must be done accordingly to the battery type that you didn't mention.

content: Phone batteries aren't really meant to be swapped out regularly. Perhaps just a portable charger?

content: You could buy one of those universal lithium battery chargers. Their primary target is camera batteries, but if you choose one in which a (typically flat and wide) phone battery fits, I don't see why it shouldn't work... You sure don't want to hook up the battery directly to your power bank.

content: I wonder why the ebay charger is missing its original packaging? Is defective and was returned? Factory reject? I would never buy it and risk having my home burn down.
