Hello!
I have a rain problem with my FP3+ (already took it apart and cleaned and dried it) and the primary suspect, the bottom module, is out of stock.
The universal chargers above seemed a bit hard to come by at such short notice, so I went to a few mobile repair shops and I found a 10Euro universal charger “HE-316 cargador universal” from “Guson Aptor Electro Store S.L.” in Madrid. It is non-existent on the internet, so I´ll attach pictures.
With this charger I got about 70% charge in around 8h.
So until I can get my hands on a new bottom module or it spontaneously recovers, I have to deal with this setup and a second battery I guess.
Important the contacts of the charger are too wide to fit into the slits of the FP3 battery, so I had to twist them with pliers. A little piece broke off of the contact because its so flimsy, but it still works fine for me.
The charger is properly connected to the battery if you can see the percentage indicator constantly changing while pluged into the socket. If it´s not moving, it´s not charging!
If you connect the battery to the charger while it is not plugged in, the blue LED will turn on, so you know you have a good connection, but the indicator (25%, 50%, 75%, 100%) is probably not showing the actual state of the battery. I didn´t test this but it doesn´t seem that important to me.
I just left this here so that, if you are desperate and in search of a universal charger, you have another makeshift option that might be available in a mobile shop nearby as a last resort.

Best regards and good luck with your repairs,
