How to Make Lipo Battery USB Charger/Adapter for Phone, IPod, MP3, Etc.




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.

Materials Required:
-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

Tools Required:
-wire strippers
-multimeter or volt-ohm meter
-soldering iron or gun (optional)
-solder and heat shrink (optional)

Purchase options:  If you can't find the materials, check out some of the following.
-LiPo batteries: 
  o 2-cell 350mAh with JST female connector:
  o 2-cell 1000mAh with JST female connector:
-male battery connector:
  o JST:
  o Deans:
  o XT-60:
-5 volt UBEC:
-Female servo lead:
-USB type A female connector:

    can i use 20Amps ESC with linear output in place of the UBEC for my charger.......

    3 Amps is the maximum output, so if your USB only draws up to 2 Amps, the BEC will support it.

    Hello There,

    I've notice that the link for the 5 volt UBEC from hobbyking output at 5 Volt @ 3 amps. Isn't 3 amps a little too much for usb ? Usb amps are usally 1/2, 1, and 2 amps. I could be wrong but I love your post.
