Hi @Michdon557, welcome to the Fitbit Community! It's great to have you here!
Let me help you with the issues you are experiencing with your Sense 2 while you are attempting to charge it.
If the device is constantly vibrating and showing the charging symbol, it is most likely because the connection between the pins on the charging cable and the device connectors is bad.
There are a few tips that may be helpful when this kind of situations arrive. See our help article Why isn't my Fitbit device's battery charging? to learn more about it.
