Setup
Charging the Flashlight
Before first use, fully charge the flashlight. The integrated lithium-ion battery is not user-replaceable.
- Locate the Micro-USB charging port on the flashlight. It is typically covered by a rubber flap for water resistance.
- Open the rubber flap.
- Connect the small end of the Micro-USB charging cable to the flashlight's charging port.
- Connect the larger end of the USB cable to a compatible USB power source (e.g., computer USB port, USB wall adapter).
- The power button LED indicator will illuminate red during charging.
- Once fully charged, the LED indicator will turn green.
- Disconnect the charging cable and securely close the rubber flap to maintain water resistance.
A full charge provides approximately 4 hours of runtime on high setting, and up to 7 hours on low setting.

The flashlight features a single push button for operation.
- To Turn On: Press the power button once. The flashlight will turn on in High mode.
- To Change Modes: While the flashlight is on, press the power button repeatedly to cycle through the modes: High → Low → Strobe.
