Nitecore EMR23 Portable Electronic Repeller

The Nitecore EMR23 is a lightweight, multi-function electronic mosquito repeller designed to deliver powerful, portable protection in a compact, travel-friendly design. Featuring both indoor and outdoor modes, it creates a 16 ft outdoor or 11 ft indoor protection zone in just 10 minutes, offering up to 8 hours of continuous, 200% enhanced repelling performance. Perfect for camping, hiking, fishing, or relaxing outdoors.

Please note that we sell Thermacell mosquito repellent mats separately, which are fully compatible with all Nitecore Electronic Repeller devices.

Equipped with Nitecore’s advanced FCB 3.0 Heating System, the EMR23 delivers efficient, stable performance by minimising heat loss and improving thermal conduction. The system reaches a peak temperature of 180°C (356°F), ensuring rapid and consistent activation of repellent mats with lower power consumption.

Power is provided by the included detachable 8000 mAh battery cartridge, offering up to 8 hours of continuous protection on a single charge. The cartridge recharges in around 3 hours and supports QC/PD two-way fast charging, allowing it to double as a power bank for charging mobile devices when removed from the unit. Alternatively, the EMR23 repeller section can be powered directly from an external USB source for continuous operation.

Operation is quick and intuitive:

• Insert one repellent mat into the placement area while the device is off and cool.
• Long-press the repeller button to activate
• Short-press the same button to toggle between low and high power modes.
• Long-press again to power off.

The integrated real-time OLED display provides clear information on mode selection, remaining runtime, and battery level, while the blue indicator lights show battery status during use or charging.

Compact, efficient, and reliable, the Nitecore EMR23 offers effortless protection from mosquitoes both indoors and outdoors, making it the ideal companion for those who like to stay outdoors without the bite.
