The Thermacell EX90 rechargeable mosquito repellent device was designed for outdoor and travel enthusiasts and travellers. Powered by a built-in Li-Ion rechargeable battery, this system heats and diffuses scent-free liquid repellent to create a protection zone of up to 20 feet and lasts up to 9 hours per battery charge. Water- and dust-resistant, durable, and easy to use, it features a rubber over-mould for an easy grip and comes with a lanyard and carabiner so you can easily hang it from a tree or tent. Plus, the audio cues and LED status indicators let you know the portable device is on or off while the quick-view window at the back allows visibility of the remaining repellent. Whether you go camping, fishing or hunting, fully enjoy the nature on your next adventure with the EX90.
