I got asked if I could take a look at some LED strip and its power supply. The owner had received a small shock from the supply while testing the LED strip.
One moment please…

I have an old cheapo 12v adapter and if you touch the 12v it gives you quite the zap on a well grounded surface
I went electroboom on one of my Xiaomi Charger and touched it to my lips. And it gave quite a tingling sensation like the one you get when you lick a 9V battery.
Tested the voltage and it was 88V
Thank You 🙂🙏❤️
i know its an old video, but im curious why you would get around 110v ac on the supply with an earth reference when it rectifies to DC at the output?
…
Bleed current should be at about 0.1mA from a Class Y1 capacitor. Nothing that will light an LED.
My chargers minus(output) wire was directly connected to transformer and the other(output) one to a capacitor, not the other way around the circuit it should be,so i guess thats why it shocked me.
When you tested the amps, where did you ground it?
What kind of Megger is that.
OK, I'm not an electrician so can someone tell me if those voltages of 100V (or 144V in case of Apple power suplly) are acutally normal? My AC voltage is 220V (Europe). I found this video when searching for "power supply shock" after I got a shock using one of these generic 12V 1A power adapters with my Netgear network switch (it was not original PSU that came with!). The network switch housing is metal and while handling it with one hand, I touched a metal PC case with the other hand and got a shock. I then placed the switch on the PC case which created a spark and tripped the circuit breaker in my house. After some investigating I found out it was a problem with the 12V power supply because I could measure 120V between its output barrel connector (both + or -) and the PC chassis. I tested the rest of them I had in my room and none of them had this problem (they all showed 0V). So I decided to discard the faulty one to make sure it doesn't kill me. Now in this video I see that Apple charger also shows 140V. What's going on ? Isn't this dangerous if that voltage then comes to the housing of the device it is plugged into ?

A faulty Y-cap is the reason why some people still get electrocuted from phone charger.
NICE video,thank you
Better just to CUT off those (why or bypass) caps?? what RF is that,and what harm does it do? nothing?
I had TWO Dell d830 laptops burn the mobo a week apart,until i found that the charger was putting out 91V AC; maybe it was a coincidence,but i do not use it anymore,i use some genuine Lenovo ones,that have LOTS of aluminum surround inside the plastic case,all around the pc board,and do not put out more than 1V AC out (besides the 19 V Dc,of course).
I suspect it's the damn GOVs at it again with their flawed rules and regulations!!
Who in their right ming would make a 19 volt DC charger that ALSO puts out 100 V AC??? only the GOVs,those pencil pushers!!
I am in the car repair business and i see their flawed acts (the GOVs!!) A LOT..
Looked like an rj11 connector for a second there
I have that same little dollar screw driver. Bet you got it from poundland huh?
I can feel the 50hz vibration of mains cycles if I stroke my fingertips lightly over the metal of my wife's Apple iPad when it's charging. Apple charger is used.
I am not particularly happy about this. Both iPads she has had have done exactly the same thing… (?)
Any cause for concern, I wonder?
I have a Meross power strip with USB ‘s and I found the floating AC voltage to be a nuisance, making touch screens erratic etc. (It can’t do sensitive electronics any good). So I took mine apart and connected the USB framework to mains earth and had no more problems.
