Nitecore EMR10X, mosquito repeller

The Nitecore EMR10X repels mosquitoes in just 10 minutes. The device makes an ultrasonic sound with a frequency between 25 and 40 kHz. Humans can't hear it, but insects can. And they'd rather not come close to it. The device also heats a mosquito-repellent mat. The EMR10X runs on 2x 21700 Li-ion batteries. These are not included. You can charge it via the USB-C port on the top of the EMR10X, and you can also use this EMR10X as a power bank. It has a burn time of up to 12 hours on 2 batteries with a combined capacity of 10,000 mAh. Burning time depends on the capacity of the batteries you use.
