by | Apr 18, 2025 | Outdoors, Personal

With the coming of Spring and Summer, the temperature starts rising, and with that come mosquitos. These pesky insects can quickly ruin your time outdoors, whether you’re camping, enjoying a picnic in the park, or just relaxing in your backyard. That’s where having an electronic mosquito repeller comes in handy. These portable devices create a protective zone that keeps mosquitoes away without the need for sprays or open flames, making them an effective solution for keeping these pests at bay. For an electronic mosquito repeller that’s reliable, efficient, and offers several hours of protection against mosquitoes, check out the Thermacell E65.

The Thermacell E65 is a rechargeable mosquito repeller that effectively keeps mosquitoes away by diffusing a proprietary repellent formula to create a scent-free, 20-foot zone of advanced mosquito protection, making it capable of repelling tough mosquitoes, including those that may transmit Encephalitis, West Nile Virus, and Zika Virus. Its area of protection works fast in just 15 minutes and doesn’t weaken over time. The device offers up to 6.5 hours of continuous protection and comes with a long-lasting refill cartridge that offers up to 36 hours of mosquito repellent and a fast-charging dock.

Engineered to target mosquitoes with precision, this rechargeable mosquito repeller provides science-led defense against mosquitos, helping you keep these pests at bay without the use of bug sprays or lotions on your skin.

Here’s our review of the Thermacell E65, where we explain how this rechargeable mosquito repeller is designed to work, talk more about its features, and go over its pricing.

DESIGN

Starting with the device’s size, this mosquito repeller has an ultra-compact form factor, measuring just 3.75 inches in diameter by 4.25 inches tall, and is also rather lightweight, weighing just 19.2 oz.

Thanks to its portable design, you can bring it with you anywhere. In fact, the device is even FAA-approved, meaning you can also take it with you on airplanes inside your carry-on luggage. Just remember to pack it in a safe way to ensure that the device doesn’t get accidentally activated during its transportation.

The device also sports a discreet design and has a fairly durable construction, as its outer shell is built of hard TPU plastic.

HOW IT WORKS?

The way this rechargeable mosquito repeller works to keep mosquitoes away is by diffusing a proprietary repellent formula containing 5.5%  of metofluthrin, which precisely targets mosquito sensors, effectively driving them away.

To achieve this, the device’s rechargeable battery powers a built-in heater, which then draws its mosquito repellent formula upwards through that generated heat, diffusing it to form a scent-free, 20-foot zone of advanced mosquito protection.

Its advanced mosquito repellent formula is rated to effectively repel tough mosquito species, including those that may transmit Encephalitis, West Nile Virus, and Zika Virus.

Its mosquito repellent formula comes in the form of a long-lasting refill cartridge that offers up to 36 hours of mosquito protection.

Once its refill cartridge is empty, you can easily swap it by simply opening the device’s cartridge container and replacing it with a new one (sold separately at Thermacell’s online store for just $19.99 each).

HOW TO USE?

To activate the device, simply push its power button at the center of its base and you’re all set.

Its area of protection against mosquitos is then formed quickly in just 15 minutes and doesn’t weaken over time.

It’s also important to note that this rechargeable mosquito repeller is specifically designed to only be used outdoors. That said, you can use it at home in your backyard, in public spaces like parks, or in remote outdoors locations, such as for times when you’re out camping.

It takes approximately 2 hours for the device’s battery to fully charge.
