If you’re looking for the highest amperage stun gun, then you’ve seen past the hype concerning voltage. When we first started selling stun guns back in 2000, the highest voltage stun gun at the time was a whopping 300,000 volts.
Soon after, manufacturers started to increase the stated number of volts to be higher than the next guy. Amperage wasn’t even on the radar. We had 400,000 then 500,000 and even a 775,000-volt stun gun. It wasn’t long till the Million volter came out and it was all the rage.
Back then, these devices worked on 9-volt batteries. Any reasonably common-sense type person could deduce that the more batteries it took, the more powerful the output actually was. This was true no matter what the stated voltage was. If a device took two batteries and was 300K volts, it was more powerful than a million-volt stunner that only took a single battery.
Comparing them side by side was another way to tell the difference between them. You can tell how strong it is when you fire them off one after the other. Without knowing any specifications, your eyes and ears will tell you exactly which one you don't want to be stunned with.
So even after the 2nd and 3rd million volters came out, there wasn't much difference in the actual output of any of them. While higher voltage means it has more penetrating power, the newer numbers coming out were more for marketing than any increase in actual electrical power. Voltage as low as 25,000 is enough to go through clothing, so higher amounts are unnecessary anyway.
In any case, it's the amps that provide the juice delivering the most energy rather than the voltage. Voltage gives it the wide open push to go through clothing, so the higher the real voltage, the better the ability to deliver the charge through thick jackets and such. Amperage is the biting force.
And in the case of stun devices, we're talking thousandths of an amp, measured as milliamps. You've heard the saying, "One amp will kill ya." Well, we're nowhere close to that when dealing with these self defense products.
Most of them are between 3 and 4.9 milliamps. This amount is enough to deliver the effect you’re after. Anything over five milliamps can overload the circuitry inside the device and burn out the capacitor. The capacitor is where the energy builds up and is stored until it's discharged through the probes. Too many milliamps and you'll burn out the unit.
One of our strongest stun guns is the Runt. It has 4.5 milliamps which are more than enough to overload the electrical impulses of the human body. The body has nerves just about everywhere so anywhere you touch the person with the probes of the stunner is going to have an effect. However, if possible, you want to go for the major muscle groups such as the neck, upper body, or even groin area to have the best effect.
The electronics inside the Runt are top quality and the thick electrodes (probes) on top deliver all available energy into your attacker. For being such a small weapon, it really does have it all when it comes to available power and having the desired effect of stopping an attacker.
Nowadays, most stun guns use rechargeable batteries. This saves you from having to replace batteries, but you do have to remember to plug in your device every 2-3 months.
The stun gun is one of the most powerful and effective tools for self defense. Handy, simple in design, and straightforward to use, stun guns are preferred in many instances for deterring an attack or controlling unruly and dangerous behavior because it delivers fast efficient results. Stun guns come in a variety of power, usually expressed in voltages. The number indicated as the voltage of the stun gun is an indication of its power, but again, it's the amps that matter.
Stun guns with high voltages are intended for close encounters. They are designed to shock by contracting the muscles and causing pain. However, they may not be effective in knocking the assailant to the ground. They are, however, quite efficient at producing a shock that will cause enough pain and discomfort in order to discourage a physical attack.
If you’ve ever experienced the discomfort of static electricity, such as when you rub your shoes against a synthetic rug and proceed to touch a door knob, then you could safely say that you’ve been shocked with about 20,000 to 30,000 volts of electricity. This does not even compare to what a stunning device gives.
