Welcome to the Community @Judic!
There are some instructions that I would like you to follow in order to make your Surge charge:
- Dirty charging contacts. Try cleaning them using the instructions in How do I clean my tracker?
- Faulty charging sources (USB port or plug) Try a different USB port or UL-certified wall charger. Do not use a USB hub.
- Tracker isn't connected to the charger Try reconnecting your tracker to the charging cable. If your tracker has a display, you'll see a battery icon while it's charging. Fitbit Flex lights up while charging. I
- Firmware is outdated. Try updating your tracker using the instructions in How do I update my tracker?
- A defective tracker. Try restarting it using the instructions in How do I restart my tracker?
If after try those steps your Surge still not charging, please contact Fitbit Support, I'm pretty sure they will help you out!
Have a nice weekend.
