I know the basic deal with stun guns- don't. They don't really work as an effective self defense option. So, I'll say it. I played with a friend's low quality no- name version, for a few minutes, and it was fun, fascinating even, so I'm going to get one. Just as a curiosity. I've stumbled across The Runt stun gun, now offered in up to 4.5 million volts at 11 milliamps. That would e the one I'd get, question is, whats the quality like? Too many that I've seen seem like they were just slapped together. Anyone had a chance to handle one, own one? Been hit by one?
The Runt 4.5 Million Volt Stun Gun.

Then what does it matter?
As pointed out, that's an improbable level of power at almost 5 kilowatts. This might be an initiating voltage over a very brief period of time, but the voltage HAS to drop during the sustained voltage needed to be effective over 3 to 5 seconds to incapacitate or you'd be carrying around a battery pack the size of Batman's belt.
Not to nitpick, but it is 50kW if you do the math. There is no way you could carry a battery that had that much power in it, and you would need something on the order of a Prius's batteries to make that kind of power.
As mentioned before it *might* be 4.5 million volts at .000007 amps, then drops down to something like 3000 V at .011 amps. I'm skeptical either way.

I can answer some of your questions (ignoring the power capabilities or lack thereof) I have handled and messed around with a Runt. They seem to be relatively well made though the fit and finish aren't bad beyond the very slight gap between the parts of the casing that seems to be common with anything made of plastic. I've never owned one myself, couldn't bring myself to spend money on something I'd never use. When you get hit with one it HURTS. It hurts BAD. I'm 155 lbs or so, at 5'7" tall, and it didn't put me on the floor right away or anything, but I felt it for a good 20 minutes after and had a twitch in my shoulder muscle for about a week.
Against someone with pain tolerance similar to or greater than mine (or against a doped up or drunk BG) I wouldn't rely on it to stop the attacker or save my life.

I'm not sure the voltage, but it was over 2 million. It was held to my shoulder for about 5 - 7 seconds, but it seemed more like a minute.

Electricty is Cool...
I've noticed that there seem to be some misunderstandings concerning the power of this stun gun.
At an amperage of 11 mA and a voltage of 4,500 kV, yes, this weapon can produce about 49.5 kW. But that doesn't even mean that it could power a single kitchen appliance, let alone eighty homes, because it produces that wattage at a very low amperage. Let me put that into perspective for you; I'll use water as my analogy. Think of voltage as the quantity of water, and amperage as the strength of the water's flow. Wattage is the combination of those two factors. For example, if there is a great quantity of water (voltage), but very little flow of the water (amperage), then the wattage is just a big lake. Yes, it's quite large, but it's not going to take any boats downstream. Okay, maybe that was a lame analogy, but you get the point. Just because this stun gun can produce gratuitous amounts of voltage, it may seen like it has a lot of power, but with the amperage taken into consideration, in reality, it doesn't. It can, in fact, be powered by a normal battery, since current draw is determined by amperage alone, and not wattage or voltage. Theoretically, I suppose that a device producing 10 million volts at 0 amps would have no current draw on the battery...but, besides the Poynting vector, within my knowledge, I do believe that that's impossible.
Anyway, look at this schematic:
It shows what a typical stun gun circuit looks like. Essentially, it works by taking a small direct current (from a battery), using an oscillating IC and a transistor to "convert it" into an alternating current (it's really a pulsating direct current), and then running it through the secondary coil of the transformer where it's amplified, and then it comes out of the primary coil. Then, the circuit collapses when the electrodes are shorted by the conductor, being human skin, in this case. Of course, that's all in layman's terms.
This particular design produces a constant current, whereas other stun guns that I've seen have a capacitor bank that is charged by the transformer, and then discharged by a switch. Actually, if I am not mistaken, that is the difference between a stun gun and a taser, unless they're just different names for the same thing.
This particular stun gun in the schematic, made from rudimentary components that can be found at your local electronics store, which is powered by a 9 volt battery, can produce about 2,000 volts. However, if there are any math whizzes reading this, don't turn that into an Algebra equation, because the power supply voltage is not proportional to the output voltage. A 4.5 million volt stun gun could also be powered off of the same 9 volt battery, for reasons that I explained earlier. In this schematic, a 9 volt battery was probably chosen not for it's power, but for it's capacity.
Damn, that was a long post; I should start charging people for these lectures.

I am not trying to pick on Fuzzy or be insulting, but he isn't the biggest guy in the world and he had this thing on him for five to seven seconds and, by his own admission, it didn't put him down. I am sure it did hurt, but I doubt it was enough to keep Fuzzy from stabbing someone in the eye should he have been so inclined.
I know you know they aren't effective weapons, but if anything illustrates this better than what he said, I don't know what it is. Anyway, sorry for not being able to comment on the quality of the Runt!
I'm about Fuzzy's size.
I don't trust stun guns to stop an adversary, but Tazers DO work! And the pepper stream (Fox Labs, IIRC) I was hit with at work a couple of months ago affected me for TWO DAYS. I was still fighting nausea if I concentrated too hard almost 24 hrs later...
(edit: that link brought back some memories. Rest in peace, Byron. We had some good times.)

Actually, no, stun guns don't work that way. It looks like Earthbound Engineer missed mentioning, that because of the way stun guns are capacitated, each "zap" is the same voltage every time, until the battery is completely dead. However, as the battery drains, it takes longer and longer between zaps. You may get 5 zaps per second at first, then it slows down.
They're still worthless, though. Getting a tattoo hurts more, IMO.
