The USB rechargeable LED LENSER P7R X is a high-performance flashlight with multiple brightness settings and IPX4 water resistance. It has a power button on the tail, and by lightly pressing this button, you can switch between two lighting modes: power mode and energy-saving mode. The included rechargeable battery can be charged, but the USB cable's charging lamp gives an error after a certain amount of charging, so it might be better to replace it. Charging LED light patterns: Charging: Red Charging complete: Green Error: Red and green flashing Contact issue: Red flashing Thank you for viewing.
