Introduction: How to Make Lipo Battery USB Charger/Adapter for Phone, IPod, MP3, Etc.
In this instructable video, I show you how to make a device that uses a LiPo (Lithium Polymer) battery to output USB power. You can use this device for charging/running any USB devices, e.g. cell phones, MP3 players, iPhones, iPods, fans, lights, etc. This assumes you have the USB cable for your device already. This solution uses a 5 volt UBEC to convert the power from your LiPo to the right voltage used by USB.
-LiPo battery (2 cell minimum, more cells are OK)
-male and female connectors for battery
-5 Volt UBEC
-female servo lead
-USB type A female connector
-multimeter or volt-ohm meter
-soldering iron or gun (optional)
-solder and heat shrink (optional)
