Hi, trying to temp charge my Fitbit over the Christmas week, I have 400 ways to do this safely, but I don’t have the pin out from the charger socket thing, as it is on my couch! I even brought the 3D printer… Please help! One will be 5V USB power, the other will be 0V. I’m 90% there’s just two pins, the further apart ones, that go on to the 3 connectors on the back of the Charge 4. Thanks!
Found that they are the same on the 3 and 4, so details here: Fitbit Charge 3 charging pinout?
