The charging port on the Darth Maul is concealed inside and requires a little bit of easy dis-assembly. Do not worry, even a young Padawan can do it.
- Disconnect the sabers from each other and also unscrew the middle connector.
- Unscrew the internal cap (the one with a hexagon)
- Unscrew buttons and knobs from the hilt
- Unscrew the small screws that were under the red knobs
- Pull the core out to expose the micro-USB charging port
- Charge for 4 hours
Refer to the pictures below for reference.
