Highest Amperage Stun Guns

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.

High Voltage Stun Guns

9 volt stun gun batteryBack 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 2 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 takedown power. Voltage as low as 25,000 is enough to go through clothing so higher amounts are not necessary anyway.

Is it Volts or Amps?

In any case, it’s the amps that provide the juice delivering the most energy rather than the voltage. Voltage gives it the 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 milliamps. This amount is enough to deliver the effect you’re after. Anything close to or over 5 milliamps will 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 deferring 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.

Just how powerful is stun gun voltage?

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.


Could be wrong but if you have a million,a billion, or a zillion volts it will pass. Once it arcs, just like as if it was a physical copper wire, It will pass any voltage that is being transmitted.

There is no step down transformer between the electrodes.

Air is an insulator. You just have to increase voltage til it excesses the insulation value. If you take a copper wire with 120 volts but use wire rated for 1 volt insulation, odds are you will get a tingle because you exceeded the insulation rating.

I think what he is trying to say is it takes a MINIMUM of 30,000 volts to make the jump.

So I have a 500,000V stun gun and I just put two 3,300 MA batteries in it and it works pretty good from the sound. is that too much? Is it potentially deadly? It hasn't burnt out the circuit so I'm wondering if its even delivering more power
The phrase "It's the amps that kill, not the voltage", is extremely false and misleading. If I lead to you a 450KV high voltage transformer line, would you want to touch it? Of course you wouldn't. We know from Ohm's law that V = I*R or Voltage = Current * Resistance. If you put a lot of voltage across your body, you're going to feel it cause if you divide the voltage by the resistance of the body, you'll get the current that flows. Sure, it may only take a few milliamps across the body for you to feel pain, but you need a lot of voltage for that. If the more voltage you apply to an object of a fixed resistance, the more pain you will feel. Yes, amps are a measure of how much current runs through the body, but you couldn't have that current without a substantial amount of voltage.
I have to admit that I had a stun gun that took 2 9 volt battery’s back in the day and it had a curve to it to get a better angle on the person so anyway there was two very large guys that was drunk and they tried to attack me and they was both wearing LEATHER jackets so I hit/stung one in the rib area and low behold that sucker was on his way down if not for his buddy to grab his other arm like from under his arm pit to stop him from going down and the guy was literally ennobled and the guy that was holding him was yelling at me to stop stop stop lol cause he could’ve heard that gun blast away and it saved my ass I really wish I knew what happened to it or would of like to know what was it like I don’t remember nothing about it but just what I typed but to answer everyone’s question I knkw for a fact they go through leather jacket lol
"First comment"

Are you aware that a current 20mA through the wrong parts of the body is enough to cause hart flimmer or even heart failure. You want a weapon to kill. You aim higher.

If not I hope to God people are not crazy enough to sell these to the bunch of idiots that don't know anything about electricy.
Amps= The Current Flow Per Second. Volts=The Pressure of the Current. That is what I know, put simply. Lastly, The Two Combined, Equal Total Power/Watts i.e. Potential Electrical Force. I AM VERY DISAPPOINTED TO HEAR THAT AT ANY AMOUNT OF AMPS ABOVE 5 MILLIAMPERES THE CAPACITOR WILL MALFUNCTION/BREAK... I WAS PARTICULARLY LOOKING FOR A 100-200 mA device, with atleast 30,000 volts.... -SIGH-.
Those of you who think 30kV is the max sent across prongs are incorrect. You can't apply ohms law because in this circuit the parts of the stun gun are ohmic but air is not ohmic.

Air doesn't really have a dielectric "resistance," but it does have a dielectric strength, which, if exceeded by enough volts, can be overcome at ANY distance. Think in your head of,..lightning, which travels, a little bit further than 1cm through air.
How much the true measure of strength! 0.5–1.0 µc = pain 1.0+ µc = intolerable pain what is the µc for this ???"
What is the Rers in a taser?
Because at that distance 30kV will break down the dielectric resistance in the air itself and arc between the prongs, thus discharging the voltage so it can build up again from scratch untill it reaches 30k (or whatever distance your progs are) this is one way you can tune into the resonant frequency a tesla coil (tuning one right now). And please don't goole this and start yapping to me about air humidity etc i just don't care....
