How safe is CES?
A. CES has an unblemished safety record. For a more deatiled analysis of that record see “safety” under the research section. Cranial electrotherapy stimulators are generally limited to less than one milliampere (mA) of current. To put this into perspective, it takes one-half of an ampere to light an ordinary 60 watt light bulb. To truly compare the work done per second by these two different currents, we must multiply the currents by the respective voltages that drive them. The product current x voltage is a measure of the rate of generation of energy, and is referred to as the power output. By definition, when a device outputs 1 ampere of current with a 1 volt driving force, the power output of the device is 1 watt. Therefore for the Alpha-Stim 100, the maximum output is (600/1,000,000)amperes x 9 volts = 0.0054 watts, or about 11,000 times less power than the light bulb. Many people do not even feel this amount of current. This is current amplitude similar to that in the human body.
