I have an extra battery for the Wii U gamepad, I searched for a charger for this battery but I couldn't find it, so I built my own.
I used a 5V 1A USB Li-ion charger I had for another project and a battery socket I removed from a spare gamepad motherboard.
Additionally, I modified the gamepad replacing the screws of the battery cover with magnets, so it is easy to swap the batteries.
