Two great tastes that taste great together? I'll admit that both are things that are guilty pleasures of mine, but I'm trying to quit right now, I swear! (Ok, I haven't jammed RF signal, and neither should you - it truly is illegal.)
The device is lightweight and small for easy camoflauging: it is the size of a pack of cigarettes.
An internal lithium-ion battery provides up to 2 hours of jamming (two bands, such as cell) or 4 hours (single band, such as cordless phone, GPS, WiFi, bluetooth, etc). The battery is rechargeable via a mini-USB connector or 4mm DC jack (a common size). Alternately, 3 AAA batteries may also be used.
