Setup
Initial Charge
Before first use, fully charge the NEBO SLYDE King 4K. The device comes with a pre-installed rechargeable lithium-ion battery.
- Locate the USB-C charging port on the flashlight. It is typically covered by a rubber flap to protect against water and dust.
- Open the rubber flap and insert the small end of the USB-C charging cable into the port.
- Connect the larger USB-A end of the cable to a powered USB port (e.g., computer, wall adapter, power bank).
- The power button will illuminate to indicate charging status. A red light indicates charging, and a blue light indicates a full charge.
- Charging typically takes 4 to 8 hours for a full charge.
- Once fully charged, disconnect the cable and securely close the rubber flap over the charging port.
