The SparkFun 5V/1A LiPo Charger/Booster is a no-nonsense circuit for generating one amp from a Lithium Polymer battery at 5V. This LiPo charger is a very economical choice that is equipped with a simple booster circuit utilizing the PAM2401 IC, and includes protection diodes so you can run multiple cells in series for an extra kick. While the booster circuit is in operation, this board can draw more current the lower the input voltage, making it perfect to deliver a strong charge in a small amount of time.
The circuit is constructed by feeding an MCP73831 charge controller IC to the LiPo port, and to the input of a PAM2401 boost controller. Multiple connection types are provided for the battery, charge source and switch to allow flexibility of application, and two LEDs provide feedback on system status. If you need more than 5V out of your project, the SparkFun LiPo Charger/Boosters can also be daisy-chained together to get a bigger bang for your buck.
This board does not possess any undervoltage or other battery protection features. So, we do recommend that you use it only with batteries with a built-in protection circuit.

Thank you for your question, we currently do not plan to as a lot of the equipment we sell is all USB B. In a few years we might begin to move that way quicker but at the moment a move towards USB C is not something we are looking at.
Thank you for your question, not necessarily mobile phones do use lipo batteries sometimes but they would be required to have a JST connector on that most LIPOs would not include.
Thank you for your question, you would need something like a micro USB to USB cable. The micro USB end of the cable would plug into the board. The other end you would need to cut off and solder to either the leads or contact points on your battery pack.
