I'm at the beach, my sense died, and I have no access to get a charger in next 7 days. I saw a lot of DIY chargers and started to make one but need help locating which pins are the positive and negative power.
I think, based on seeing people having a depressed pin and having charging issues that it's port 2 (+) and port 1 (-), per my attached picture.
can anyone here confirm which ones are negative and positive. I know this is a weird ask but can't find anything on the internet.

Fitbit Sense Charger Connector Pinout. Thus, your number 4 pin is 5v+ and your number 2 pin is ground. Your pins number 3 and 1 are Data- and Data+ respectively.
