These are the components you need for building the portable USB charger circuit.
These are all pretty standard components, so you can probably get these at your local electronics supplier if you have one.
If not, you can buy them at one of these online electronics shops.
|1||Resistor||330 Ω||1||Light-Emitting Diode||Standard Output||1||Rectifier Diode||1N4001-4007|
|1||USB Socket||Type A|
|1||Battery Connector||6 x AA battery|
That’s the bare minimum. But there are a few other soldering tools that can make your life easier. Learn about the soldering tools I use here.
The following components aren’t required, but can be useful to improve your charger:
