Hi !
I made my own Wii U gamepad/RP3, following most of the Banjo Kazoo’s one (see link above), but I’d like to allow my system to work on a power supply when the battery is out. I don’t mind having 2 different power connectors (one for the battery charging, one for the direct power supply).
I thought about a few leads, but don’t know if it will work… or make the battery explode in my face B-) :
Schematic :
1 - Is it possible to connect a power supply directly to the Powerboost 1000 basic "power in" ? Didn’t find anything on this on the net… If so, is it ok if I just put a diode on the way of the + of the battery to protect it from getting power from the power supply ? And what should be the diode characteristics ?
2 - If not, can I put the power supply after the powerboost ? With a diode to protect it from getting power in his « power out » connector…
3 - If not… HELP B-) !!!
Shopping list :
- the power supply I’d like to use (need almost 4A) :

Re: How to power my system from battery or power supply (Lion-ion battery + Powerboost 1000 Basic)
I'm sure it should ! If I understood something ...
But thanks ! I'll try to understand his solution, even though it's a bit complex for the electronic noob I'm.
That's why I was thinking about making two different ways to supply the system (with 2 connectors), just secured by a diode or a switch. I thought it would be easier, but I'm maybe taking a wrong direction...
It's strange to find nothing simple about "dual power" (battery + mains supply)... Is it such unusal ?
