Introduction: 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

Step 2: Do Your USB for Power Supply

Step 3: Mount the Components

Step 4: Identify the Input & the Output of Your Project

Step 5: Connect Round PCB With the Input & the Output Showed in Step 4

Step 6: Mini Portable 5Volt in Action

Portable power supply is always a good idea.

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.

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.

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..

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)
