Nitecore EMR40 - Portable Mosquito Repeller USB-C 10h Outdoor Indoor

The Nitecore EMR40 is a high-performance portable electronic repeller, designed for outdoor enthusiasts, hikers, anglers and gardeners seeking reliable and hassle-free mosquito protection. Its FCB 2.0 heating system reaches 165°C for 200% more effective active ingredient diffusion, creating a 16ft protection zone outdoors and 11ft indoors. With its built-in 7800mAh battery delivering 10 hours of continuous protection, weighing only 229g, the EMR40 is the ideal portable mosquito repeller for all your extended outdoor activities.

FCB 2.0 Performance and Extended Runtime

The FCB 2.0 system accelerates active ingredient release from repellent mats for maximum effectiveness within minutes. Two adapted modes: Outdoor mode for a 16ft protection zone in open air, Indoor mode for 11ft in semi-enclosed spaces. Its Li-ion 7800mAh (28Wh) battery recharges via USB-C 5V/2A (10W), even during operation for uninterrupted continuous protection. Four battery level indicators display remaining runtime in real time. The memory function automatically reactivates the last mode used.

Portable Design and Versatile Use

The included clip attaches easily to backpacks and MOLLE straps for hands-free protection on the move. Compatible with standard 34mm × 48mm mats (1 mat) or compact 35mm × 22mm mats (1 to 2 mats), including Nitecore MRM10 mini pads. No liquids, no flames: solid-format pyrethroid mats eliminate all risk and mess. At 61mm × 90mm × 40mm for 229g, the EMR40 fits in any bag to accompany all your outdoor adventures, from trekking to night fishing.
