JAX 121A-16 Mobile Signal Jammer: 16 bands all-in-one frequencies blocking

Mobile Signal Jammer — Safety Alarms & Signals, JAX

Meet the JAX-121A-16 Mobile Signal Jammer—your go-to handheld for silencing the digital noise. This little powerhouse doesn't just block cell phone signals; it takes down LOJACK GPS, Wi-Fi, and RF signals across a whopping 16 bands. And yeah, it's got the muscle to back it up, thanks to a high-efficiency aluminum alloy radiator and a cooling fan that keeps it chill under pressure. Plus, with a built-in 7.4V/12000mAh battery, it's in for the long haul.

So, what's in the box? Well, for starters:

  • 16 watts of pure, unadulterated power and antennas that don't just whisper but shout.
  • A jamming range that flexes from 2 to 25 meters—because sometimes you need to keep things close, and other times, not so much.
  • A DIP switch that lets you pick your battles, turning bands on or off without messing with the others. Handy, right?
  • A nylon cover because who doesn't love a gadget that's as easy to carry as it is to use? Slip it on your arm or belt and you're good to go.
  • And because we know you're always on the move, a car charger's thrown in to keep the party going wherever you are.
