That's a good question! When it comes to stun guns, the voltage can be a bit misleading if you're just looking at that number alone. You'll often see stun guns advertised with really high voltages, like millions of volts. While those numbers are technically accurate in terms of the open-circuit voltage, it's not the full story of their effectiveness. In general, stun guns can range from tens of thousands of volts up to several million volts. However, what really matters for stopping power isn't just the voltage, but also the amperage (current) and wattage (power). A high voltage with very low amperage won't be as effective as a device with a lower voltage but higher amperage. Most consumer-grade stun guns are designed to deliver a high voltage but low amperage, which is why they're generally non-lethal. The comparison between different models and types often boils down to the overall energy transfer. Some higher-end models might focus on delivering a more effective current or pulse duration, even if their advertised voltage isn't the absolute highest. It's a bit like comparing a quick, high-pitched static shock to a more sustained, deeper jolt. Hope that sheds some light on it!
