E-cigs. Shocking you?

[jkais3r]

So. Whenever I plug my ecigs into my laptop to charge (yeah I know get a wall adapter, but that's just too far away ), I've noticed a few times where the metal on the outside, such as with my ego twist, will shock me. It's done it on my ego passthrough, and also my brand new mvp2. That mvp2 gave me a good jump.

They're all genuine, but has anyone else noticed something similar? When I googled it all that came up were idiots blowing up their ecigs.

Edit: I didn't mean shocking while using, I just mean shocking as in you accidentally brush up against them or something like that and get a tickle.

You positive you're not just dealing with static discharge?

Being its winter now and everything is extremely dry, i can literally walk across my living room carpet and get a pretty decent shock from my comp tower just by plugging in a flash drive.

Yep I agree, it's static discharge. During the winter months I get shocked from everything, light switches, fireguard, laptop, even my lovely wife...

You get the cherry! This is my first post.
I would have thought that the current limit on a laptop's USB plus would prevent any noticable shock sensation, but I must be wrong.
If you have a meter, you can check from your mod's case to ground. I'd like to hear what you find. I know that where I am(central Nebraska), if I walk around, static electricity is enough to make me jump when I touch anything grounded.

Not static discharge. I've tested it by after getting the tickle moving it away and touching it in the exact way I did before. I'm an electrician, I know what a zap feels like

Great suggestion connelley! I'll have to grab my multimeter and check that out and report back to what I find.

It is not static discharge, as if I do not move, I continue to get the tickle of electricity.

Well, all i can say is that if its happening across multiple devices and delivery systems, it has nothing to do with the e-cigs themselves.

Sounds like the ground on your USB is not at the same potential as true ground. Are you generally touching something else when this happens?

42 volts with my mvp2....

Let me go check some other things to verify the meter is working.. Which I'm 99% sure it is..

Alright. 42 volts from case to me.

0v from me to ground.

.5v from case to direct ground.

Something's fishy here.



*I wouldn't doubt that it is the laptop its' self doing it. I think the answer that sums it up is that the laptop does not have the same potential to ground. Which makes sense because it is essentially a separately derived system and does not know ground. Therefore it has no idea what ground is, and the resistance of me is enough that stray current will flow.

I once saw a very primitive voltage tester that used nearly the same concept, put your positive lead on the hot, hold the other lead in your hand, you get a tickle and a light turns on. Uses you as the path to ground even though you are not grounded.

And I believe that sums up what is happening with my situation.

hmmm could someone be running a Tesla coil in the area??
