Power Bank Inside a USB Cable

How to make a simple power bank, building tiny powerbank inside a USB cable.

Watch my new video about charging https://youtu.be/5x6VlAL29W8

A couple month ago I come with idea to build diy power bank and almost immediately this idea become to live.
It is obvious that small battery can’t provide enough power for phone to charge it, because thermodynamics laws always in action, but it is a lot of other applications where this cable can be very useful.
In the end of the video you’ll see that bigger power bank is better.

All part and components used in this project widely available and can be salvaged from old and broken devices, for example:
Tiny battery can be salvaged from old Bluetooth headset;
Charging/boosted board in size which used in video, commonly used in cheap single cell power banks;
Case or USB project box, can be salvaged from voltage boost cable;
Micro USB cable or Lightning, USB C, mini B etc., cables always lie around :)
If you have any questions, you can olveys live them in comment section.

Hope you enjoy what I do :)
