I'm here to show a tool that is really handy to have. It costs 5$ and it is pretty much the power supply you need while you create your GBZ.
It is a powerbank, but a bit special. It comes with no batteries in it, and you are able to draw 3.7v, 5v, 6v, 9v, or 12v.
The best of it is that you have 2 output. One USB that is locked at 5v, and one as a DC Jack.
The batteries to put inside are 18650 standard cell that you can find in computer batteries (Where I got mine) and it has 6 slot.
Why is it so nice ?
Once I recieved the screen, I got it with a DC Jack to nothing cable, which was supposed to plug on the screen side, though I did not have any other cable with that much AWG so I used it to wire my power to the raspberry pi and the screen. And guess what ? Now my Gameboy that has the pi, the screen, the controller linked inside can directly connect to the battery without hassle, and without taking care of the powerboost yet, nice to try your GBZ before mounting it.
And you can try your screen even before modifing it to use 5v since it can delivers 12v
The last advantage is that if, like me, you need to move around your house with the pi, you are not blocked because of the wires.
