F12 Ultrasonic Anti Recording Jammer Device

F12 Ultrasonic Anti Recording Jammer Device for private meetings

The F12 is an ultrasonic anti-recording device built for spaces where keeping conversations private matters. It is aimed at buyers who want room-level interference coverage rather than a handheld recorder or audio accessory.

360° interference coverage

Available listings describe the F12 as using ultrasonic interference with a 360-degree coverage angle. That makes it relevant for a meeting room or desk area where audio recording could come from different directions. The effective range is listed as up to 8 metres, so it is best considered for small to medium rooms rather than large halls.

Built-in rechargeable battery

The verified battery spec is 9800mAh with a 12.6V lithium-polymer battery. Published listings also note a continuous run time of about 2 to 4 hours at peak output, with longer use possible in lower-power modes. If you need longer sessions, the power setup matters more than the compact tabletop form.

Desktop-friendly speaker-style body

Listings describe a speaker-style housing, ABS construction and a tabletop design. The stated size is 260 x 130 x 100 mm, with a weight of about 1,050g on one retail listing. That makes it more suited to a fixed spot on a desk or conference table than to carrying around in a bag all day.

Simple power and control

The device is listed with a wireless remote control and 15V/5A charging or power input. It also includes an LED battery indicator on some listings, which helps you keep track of remaining power during use. Buyers should check the exact package details on the product page before ordering.

Who should consider this model?

This F12 listing makes sense if you want a privacy-focused ultrasonic anti-recording device for office meetings, consultations or other controlled indoor conversations. It is less about general electronics use and more about a specific recording-interference function, so shoppers should only choose it if that is the feature they actually need.
