Introduction: Mini Portable 5V With USB-A Port

Picture of Mini Portable 5V With USB-A Port

Mini portable 5Volt with USB-A port is ideal for Arduino and more electronic projects that need 5 Volts for working.  This project is mounted on a round PCB of 16mm diameter with an input of 9Volt and an output of 5V through an USB-A port.

Step 1: List of Materials

The parts are the following:
1 Round PCB of 16mm Diameter (Part No. 276-004, Radio Shack)
1 Electrolytic Capacitor of 100mF, 25V
1 Electrolytic Capacitor of 22mF, 25v
1 Voltage Regulator of +5V
1 Battery clip for 9V
1 9V Battery

Portable power supply is always a good idea.

braulio777 (author)2016-11-28

I enjoyed developing this project.

braulio777 (author)2016-11-28

Thank you for viewing this project.

braulio777 (author)2016-11-28

This project is for you.

Nice contribution. I think I'm going to make one and use it as an emergency USB power supply to charge my phone when away from a power source.

braulio777 (author)ringai2013-01-02

Thanks, I'm happy because this project can be very useful.

This will not work on all phones. Many phone, namely smart phones, require a bit of power to come across the data wires before they will enable charging. Great project for simple things like arduinos but not so much for smart phones.

Thank you!

ringai (author)mpilchfamily2013-03-14

I didn't know about the need for power on the data lines. I just tested my HTC G2 with a USB cable having only the the power lines connected. It charged okay..

braulio777 (author)2013-01-02

Effectively, Philip, you're right. Thank you for your feedback

Another approach is to use a cheap USB car adapter. While they're designed to operate on 12 volts they'll work fine when attached to a 9 volt battery.

In the step 1, I have included where you can buy the round PCB and the part number. The completed information is: Round PCB Kit (Part No. 276-004, Radio Shack)
