We've got a client who needs to run controlled RF sensitivity tests in a lab environment, and the variable range on this thing—2 to 20 meters depending on signal strength in the room—actually makes it useful for that kind of work rather than just blanket jamming.

Handheld Signal Jammer Front View

It covers GSM, CDMA, 3G, 4G, 5G, WiFi at both 2.4 and 5GHz, GPS across L1-L5, and Bluetooth, with 12 omnidirectional antennas each pushing 0.7W for a total of 8.4W output, and the built-in 10000mAh battery (7.4V) gives you about 120 minutes of run time before you need to plug it back in.

The cooling system uses an alumnum alloy radiator with dual fans, which is pretty much essential because running all 12 bands simultaneously generates noticeable heat, and the unit weighs about 1.5kg so it's portable but not something you'd want to carry all day—it's better suited for stationary or vehicle-mounted use than prolonged handheld operation.

Signal Jammer in Use

Also, the MOQ is reasonable for a custom unit (usually 10 pieces or so depending on branding), and they'll adjust frequency bands or packaging if you ask, but lead time can stretch to 20 days or so if you need a non-standdard band configuration.

One thing to flag: teh 8.4W total output means it's not going to punch through strong cell towers at 20 meters—in dense urban areas you're probably looking at 5-8 meters effective range, which is fine for a small room or vehicle but not for an open parking lot.

Frequently Asked Questions

What is the minimum order quantity (MOQ) for the HS-S12J signal blocker?

Our standard MOQ is 10 units for the HS-S12J. If you need fewer for sampling or testing, we can work that out — just let us know.

How long does it take to ship a bulk order of the HS-S12J, and can you customize the frequency bands?

Lead time is typically 15-20 working days for a standard bulk order. Yes, we can customize the frequency bands to match your local regulations — just tell us which bands you need to block.

Do you provide certifications or quality documents for the HS-S12J, like CE or FCC?

We can provide CE, RoHS, and FCC reports upon request. Just confirm which certifications your market requires before placing the order.

Why does the blocking range vary from 2 to 20 meters, and how can I get the maximum range?

The range depends on the signal strength of the target network — weak signals like 5G or GPS may block up to 20 meters, while strong 3G/4G signals closer to a tower might only block 2-5 meters. For best results, test it in your specific environment.

How should the HS-S12J be stored and what's the packaging like for wholesale orders?

Store it in a cool, dry place away from direct sunlight. For wholesale, each unit comes in a foam-lined box with all 12 antennas and the car charger included, packed in sturdy cartons for shipping.
