this is an easy project to make an 5v portable power bank for just 2$!

Step 1: Parts

The parts you will need for this project is:

* 3x AAA batteries

* 3x AAA battery holder

* 5v step-up

* SPST switch

* Enclosure

* Hot glue

Step 2: Cut the Wires

Cut the wires from the battery holder to the size you want them to be.

Step 3: The Switch

My switch was a little bitt to big so i had to bend the two mounting plates.

Step 4: Soldering

Solder the ground wire to the 5v step-up module and solder the switch to the positive wire, take an red wire that you cut off from the battery holder and solder it to the other pin on the switch and solder the other and of the wire to the positive connection on the 5v step-up module. When you are done whit the soldering remember to test it.

Step 5: Gluing

Glue the module to the battery holder whit hot glue or superglue, I used superglue first but the module fell off the battery holder when i moved it later so I used hot glue instead. NOTE: never ever glue an switch whit superglue! The glue always finds an way to get inside the switch :P

Step 6: Enclosure

Make an nice enclosure for your project! I really want an 3D printer but I don't have one so i made my enclosure out of some hard paper I had.
