Applications

1). DIY a mobile power supply, then only need to enter a battery-powered, you can output 5V voltage for your phone, MP3, MP4, PSP charger, very simple and convenient.

2) boost charger, you can use 2 AA batteries or lithium batteries to charge your 5V devices.

3) In order to power your electronic devices when your device needs 5V power supply, when, however, only the section you are now in the hands lithium battery-powered, with a boost to our module can be 5V, solve your problems.

4) system-level power supply before, when you do a project when the input battery-powered (1-5V) time, and your system board and requires a 5V regulated power supply, then you choose this module we will your best bet, do not debug directly on the machine can work easily achieve efficient high-power boost.
