Thermacell EX90 Review: Cordless Mosquito Defense That Actually Works
What Is It?
The Thermacell EX90 is a rechargeable, cordless mosquito repeller designed to create a scent-free 20-foot protection zone against mosquitoes. Built for patios, camping trips, and backyards, the EX90 is powered by a lithium-ion battery and uses Thermacell’s signature heat-activated repellent cartridges.
Unlike sprays or zappers, it works silently and odorlessly, making it a favorite among outdoor lovers who want peace without pests.
Key Features
20-Foot Protection Zone: Creates a bubble of protection using a heat-activated repellent that mosquitoes hate but humans can’t smell.
Rechargeable Battery: Built-in lithium-ion battery provides up to 9 hours of runtime per charge via USB-C.
Odorless & Silent: No DEET, no open flame, and no smell—you won’t even notice it’s running.
Replaceable Cartridges: Uses Thermacell’s repellent refills that last for 12 hours per cartridge (cartridge and battery are separate runtimes).
Weather-Resistant Design: IP54-rated for dust and water resistance, built for outdoor use in variable conditions.
Eco-Friendly Alternative: Reduces the need for sprays or candles that rely on chemicals or combustion.
One-Button Operation: Simple to activate with a single power button and indicator light to show battery status.
Compact and Portable: Stands easily on tables or packs into a bag without bulk. No cords required while operating.
Performance in the Field
The EX90 truly delivers on its promise of silent mosquito protection. In backyard settings, it noticeably reduces bites within 10–15 minutes of activation. The protection zone holds well in calm conditions, and even in light breezes, it still performs better than expected.
Battery life is reliable, and a full charge easily covers an evening on the patio or by the tent. Best of all, there’s no buzzing, no zapping, no citronella cloud, and no sticky feeling from sprays. It’s as low-maintenance as mosquito defense gets.
The refill cartridges are a recurring cost, but each one lasts 12 hours, and the convenience is worth it.
