Echo Dot Battery Case

This is an battery-case for your Echo Dot, so you can take Alexa anywhere you want.
An 2000mAh battery will give you a decent battery life of 4h-ish or more.

You just need to add a few electronic components to it:

- male micro-USB plug
- TP4056 charge/protection IC
- boost converter
- flat LiPolymer battery e.g. from cellphone
- cable

Probably you also need to sand down a bit on the back in order to fit the plug.

Feel free to adjust my Fusion360 file to your needs.
