The Adjustable LiPo Charger parts required depends on your input power supply for charging and the size of the LiPo battery used. At the bare minimum, all that's needed to charge a LiPo battery sufficiently is a micro-B USB cable to connect to either a computer USB port or a wall adapter. We also have 5V wall adapters with a USB cable attached.
