The problem with conventional mosquito repellers, they're not travel-safe, especially those that run on fuel.
The Nitecore EMR20 runs on built-in batteries, can function as a powerbank, and runs on repellent mats to repel mosquitoes.
This solves the problem of traveling as it's airline safe and it fits nicely into a pocket or bottle sleeve.It can be run indefinitely as well when plugged into a USB power supply like a power bank, power station, or wall plug.
If you've been looking for an alternative to sticky mosquito patches, oily sprays and smelly coils, the EMR20 is the perfect companion to take with you on your next outdoor adventure!
