Product Information

This newly launched all‑in‑one portable wireless signal blocker comes with 16 jamming channels. It is capable of suppressing a wide array of devices including Android handsets, tablets, iPhones, Windows smartphones and more that run on 2G, 3G, 4G and CDMA 450 MHz networks. It also blocks LOJACK, GPS, 5 GHz Wi‑Fi, UHF/VHF walkie‑talkie signals, together with common RF frequencies such as 315 MHz, 433 MHz and 868 MHz. This model has remained a popular choice since 2020 and continues to be sought after.

EO1603US Adopting a handheld form factor with concealed antennas, this 16‑band integrated jammer cuts off cellular signals, LOJACK, GPS, Wi‑Fi and RF transmissions. It delivers a total output power of 12 W. Its effective jamming radius ranges from 2 to 20 meters at -75 dBm; the actual coverage varies according to local signal strength. Two sets of antennas with different lengths are supplied, supporting hidden installation or optimized blocking performance.

An LCD screen is fitted to display battery percentage, real‑time working voltage and current. The housing is made of ABS material, equipped with an advanced cooling assembly consisting of internal cooling fans and an enlarged heat sink, keeping operating temperature below 50 ℃. Independent DIP switches allow users to enable or disable any single frequency band separately without affecting other channels.

EO1603US Power options include a car charger and 12 V DC / AC power adapter. Equipped with a large‑capacity built‑in battery, it can run continuously for over 120 minutes and supports repeated charging conveniently.

Note

Many countries impose import restrictions on mobile signal blockers due to spectrum licensing rules and local telecom laws. Please verify your local telecommunications regulations before placing an order. We can adjust CDMA, GSM, DCS and PCS frequency configurations to match the frequency bands used in your target market. The actual jamming distance is affected by ambient signal strength and surrounding environmental conditions.
