Cell phone jammer: test and comment.

With the experience of these devices for several years, I can have an almost objective opinion on this issue. Around 2007, I got my first jammer. This is the "basic" model.
There are several types of models that can be distinguished according to power types:

- portable jammers operate on internal rechargeable batteries.
- the main line runs on the main line.

In addition to the frequency range of coverage: GSM, CDMA, 3G, DCS...

The most common pattern so far is this one, with the original packaging of a plug converter:

GSM/CDMA/DCS/PHS / 3G

Some loose comments about the model:

The load was long enough to discharge. Basically, for the first model, the second day I calculated the operating costs of an hour.
Similarly, if we don't use it, he will soon relax himself. There is no way to know when the charges will end.
In the most recent model, all these flaws have been corrected, waiting for the diode to close to know that the charge is over, and over time, the interference doesn't seem to be self-discharging.
