Handheld Small Portable 12 Frequency 2-5g Mobile GPS GSM Jammer

It can block 12 independent frequency bands, depending on the model (American version or European version). Coverage includes: 2G (GSM 850/900, CDMA), 3G (2100MHz), 4G LTE (700/800MHz), WiMAX (2600MHz), Wi-Fi/Bluetooth (2.4G &5.8G), GPS/GLONASS/Galileo L1, Lojack/XM Radio (173MHz), and remote control commonly used frequency bands (315MHz, 433MHz, 868MHz)

In the environment where the transmission strength is less than or equal to -85dBm,the maximum shielding radius is about 0-30 meters. The actual range will vary depending on the transmission strength and density of the surrounding base station.

Built-in 12000mAh rechargeable lithium battery, it can last for about 2 hours at full power. Supports three charging methods: AC power adapter (100-240V), car charger (12V DC), and charging the built-in battery through the DC 12V charging port on the device.

The product is designed to only interfere with the frequency range corresponding to the target device, and will not interfere with the base station.Its operation complies with the specific absorption rate (sar) standard of the International Committee for the Protection of Non-Ionizing Radiation (ICNIRP) to ensure the safety of the human body during use.

There are 12 independent DIP switches on the top of the device, each corresponding to a frequency band.Users can turn on or off any frequency band separately as needed to achieve precise control.
