W9 Hidden Wireless Camera Blocker (2.4GHz / 5GHz / 5.8GHz | 15m)

The W9 ( W8 upgrade) hidden WiFi jammer doesn’t try to be loud or complicated in its structure. Its dimensions of only 185 × 80 × 40 mm make it easily mistaken for a regular power bank, allowing it to blend seamlessly into everyday environments without attracting unnecessary attention.

Despite employing a built-in antenna design, its heat dissipation performance is comparable to other jamming devices with built-in antennas.

Heat management is handled through a combination of flame-retardant ABS housing, an internal cooling fan, and a network of ventilation openings. At first, this might look like a standard safety setup, but the layered design actually plays a more important role in maintaining stable output over time.

As you can see, airflow isn’t treated as an afterthought here—it’s integrated into the structure itself to prevent performance drop during longer operation.

This wireless network blocker supports multiple common WiFi frequency bands, including 2.4GHz, 5.2GHz, and 5.8GHz, with an interference range of up to 15 meters. The interesting part is not just the range itself, but how it keeps up with both older and newer wireless standards at the same time.

This solves problems such as children secretly using Wi-Fi at night or employees using their phones during work hours. More importantly, 4G/5G mobile networks can continue to operate normally during interference, preventing overall network outages.

Of course, some people may use hotspots or 4G/5G signals; for those, you can learn about our P-N31 Portable 31-Band Full Spectrum Signal Jammers, which can interfere with signals including GPS and the latest Wi-Fi 6E/7E.

A 5200mAh integrated lithium battery supports roughly 3–4 hours of continuous use. That might not sound dramatic at first glance, but considering the portability factor, it becomes far more practical in real-world scenarios where constant power access isn’t guaranteed. In other words, it keeps running when mobility matters most, without turning the device into something tied to a wall socket.

However, to extend usage time, the included 220V power adapter ensures a stable and continuous power supply when needed.

The W9 features a dual-switch design, allowing users to control WiFi bands separately:

• Switch 1: 5GHz WiFi control
• Switch 2: 2.4GHz WiFi control

Finally, there’s something you might not have noticed at first glance. The bluetooth blocker is equipped with a built-in battery indicator light. It provides a simple yet clear way to monitor power status at any time.
