Triple the protection, triple the peace of mind - mosquito repelling, ultrasonic pest deterrent, and power bank all in one device.
EXPERIENCE TOTAL ENVIRONMENTAL CONTROL - You're setting up camp in bear country when you hear rustling. While the EMR25's 16-foot mosquito barrier keeps you bite-free, its 40kHz ultrasonic deterrent creates an invisible shield against mice trying to get into your food stores and snakes avoiding your sleeping area.
POWER THROUGH THE LONGEST ADVENTURES - Day three of your backcountry expedition, and your group's phones are dying. The EMR25's massive 12,000mAh battery has been protecting your campsite for 36 hours straight and still has enough juice to fully charge four phones before you even think about finding power.
ADAPT TO ANY PEST CHALLENGE - Morning brings mosquitoes, evening attracts mice to your food, night might bring curious skunks. Instead of juggling multiple devices, tap the EMR25's dual controls to activate exactly the protection you need, when you need it.
FEEL THE DIFFERENCE OF TRUE VERSATILITY - Fishing by a marshy lake, you activate mosquito protection. Later, setting up camp near old cabins, you add ultrasonic deterrent for rodents. Each function works independently or together, giving you complete control over your outdoor environment.
TRUST IN EXTENDED RELIABILITY - The bright OLED screen shows exactly what's active: mosquito mode running for 8 more hours, ultrasonic mode just activated, battery at 67%. You always know your protection status and remaining runtime.
CARRY SERIOUS CAPABILITY WITH EASE - At 295 grams, the EMR25 weighs less than a water bottle but delivers professional-grade protection that serious outdoor enthusiasts depend on for multi-day adventures.
Mosquito repelling, 40kHz ultrasonic pest deterrent, and 12,000mAh power bank combine into one comprehensive outdoor protection system that handles every pest challenge.
The 12,000mAh battery provides 12 hours of continuous protection while maintaining enough capacity to charge multiple devices throughout extended adventures.
Beyond mosquitoes, the 40kHz ultrasonic function deters mice, snakes, cockroaches, and skunks - giving you complete environmental control in any outdoor setting.
Dual independent controls and OLED real-time display let you customize your protection strategy while monitoring battery life, runtime, and active functions.
The Science of Complete Outdoor Protection
Picture having a personal force field that operates on multiple frequencies. The EMR25's FCB 3.0 heating system activates professional repellent mats in seconds, creating your 16-foot mosquito-free zone, while simultaneously generating 40kHz ultrasonic waves that remain completely inaudible to humans but effectively deter rodents and other pests.
The precision engineering means you feel the gentle warmth confirming your mosquito protection is active, while the ultrasonic deterrent works silently in the background. No annoying sounds, no interference with your outdoor experience - just comprehensive, invisible protection.
This dual-technology approach means whether you're dealing with the mosquito swarms of a humid evening or the curious wildlife of remote camping, your EMR25 adapts to provide exactly the protection your environment demands.
12-hour protection runtime and 12,000mAh power capacity support extended adventures. Ultrasonic deterrent keeps wildlife away from food stores.
Dual-mode protection handles mosquitoes during dinner parties while deterring mice and other pests around outdoor kitchens and dining areas.
Silent ultrasonic mode won't spook game while providing comprehensive pest protection. Extended battery life supports long outdoor sessions.
Essential for construction, surveying, or research in pest-prone areas. Comprehensive protection plus reliable device charging for long workdays.

I brought the Nitecore EMR06 TAC Electronic Mosquito Repellent with me and my dog to the park over the weekend, and it worked really well. I noticed far fewer mosquitoes around us, which made our time outdoors much more comfortable. It’s compact, convenient, and easy to carry. Highly recommended for pet owners and anyone who enjoys spending time outside!
Small and handy
I purchased the EMR product for the second time because of the excellent experience we had with the EMR 16. My son is usually very susceptible to mosquito bites, so we decided to let him use it during his Primary 5 camp. He used it throughout the night, and to our surprise, he returned home without a single mosquito bite. The product performed exceptionally well and gave us great peace of mind. Based on our experience, this is an excellent product that truly works, and I would highly recommend it to others.
I love it. It keeps the mosquitoes away that I bought 2 boxes at one go. No buzzing no bites. Nitecore Mosquito repellant mats keeps them away.

Love the long battery life without having to worry about recharging for long walks or hikes.
I was hyped about the product but after trying it for 1 day, I was disappointed. The runtime does not last for 10 hours as claimed.
I’ve been using the EMR40 with a mosquito repellent mat and I’m very satisfied with it. It’s easy to carry, has great battery life, and does an excellent job keeping mosquitoes away during my morning and evening dog walks at the park.
“I’ve been using this mosquito repellent mat with my EMR40, and it works very well. It effectively keeps mosquitoes away when I walk my dog at the park every morning and evening.
My son's blood is tasty to mosquitoes. So he is suffering in camp. But after using the Nitecore EMR40 Electronic Mosquito Repellent last night, he sent me a message this morning that it really worked! He didn't get a single mosquito bite last night! I am so glad that my research paid off!
Did not open as it is a gift. Seller shipped fast and item came well packed.
I have been using the mosquito repellent mats daily as it is effective to prevent mosquitoes and flies from flying into the house. This is my reorder of 3 boxes every two months. Thank you!
i have been using the mosquito mats for about 1.5 years and it has helped to keep the mosquitoes away especially during the period of high dengue fever incidents. It's safe and easy to use at home.
Small form factor and the power on button is design to prevent accidental on or off. Love it.
I have been using the mosquito mats daily for about 2 years in my home. It is effective and flexible as I can place it anywhere at home to prevent mosquito coming into the home, especially when Singapore is experiencing regular dengue fever outbreaks. Prevention is better than cure.
Handy tools to bring when outdoor . Really keeps mosquitoes and bugs away . Great !
Arrived in time when the stock is depleting fast...
Replacement purchase. Have been a life-saver for my mosquito-prone wifey and daughter.
It's a very effective repellent device. Non of us got bitten on the entire trail walk. However, the device only lasted for about 3.5 hrs real time use instead of its claimed 5 hrs duration even though it was charged to full the night before our walk.
Super handy. Just clip and go. Love it!

Awesome piece for the add on blinker holder.Secured firmly.
Used 4 times so far and had bites twice. Doesn’t seem to do anything for house flies. Can’t really tell when to replace the cartridge. Overall experience not that great. Not to forget it’s abit heavy
