I have heard many people say it is impossible for a 5V Charger to electrocute or kill someone. But based on personal experiences, I tell you it can electrocute and kill.

I am an electronic technician. The first time I experienced this was many years ago. I had this charger that will shock if I do not have any footwear on whenever I plug it to power to charge. This made me want to find out why this is so.

Later on, I read on the internet about a girl who was killed by using her phone while it was charging. Though the phone brand was a popular one, so their engineers denied the possibility of a 5V Charger killing anyone because the voltage is very much too low.

Also this morning, I read on front page about a man that died while using his phone. Firstly, I condemn the carelessness, because it's been a given warning on several occasions not to make a call with your phone while it's being charged.

Yes, the voltage is very much too low, but there is something missing in some Chargers. This is one reason I'll not advise you go to the market and buy just any random charger for use, because there is something missing in most of them!

This missing component, I noticed and found it in a Nokia Charger. Then observing all Nokia Chargers I find, it's in them! Meaning Nokia has discovered this widely ignored safety precaution long ago.

All Chargers come with 2pin plugs. Even the ones with 3pin plugs has the third pin made of plastic, which makes it impossible to link it to direct Earth, but Nokia discovered this method of internal Earthing, as this clears the voltage leak/reflection effects.

Some Chargers today still has that same component missing in it. So when you plugged it to an outlet, you feel a voltage/current reflection, which is very dangerous, as it can electrocute and even kill.

Once you plug your phone to charge, the first way to notice is without you having any footwear on, feel the body of your phone with one finger by swiping on it very slowly, (mostly phones with aluminium or iron frame) once you feel that voltage reflection, your charger is not safe for use.

After I discovered this hitch, I checked a random charger purchased, and alas this component was missing!
Then I got it from the market and fixed it in. And the voltage shock/reflection stopped.

So, be observant.
Be careful.

Modified:

The missing component comes in different sizes, types, part number, shapes, and manufacturer.
It's used to create a ground between either the AC input, or /negative/anode, or positive/cathode of the bridge rectifier diode, to the output, either to negative or positive; (mostly negative output) which will clear off any possible voltage/current reflection to the output.

Note: If the one/type used is not the appropriate, it can cause severe reactions or electrocution. So, take note to use Metal Oxide Varistor 471K.

You're welcome.

Oga, the missing component no get picture? Let people see what you are talking about by attaching pictures pls

Op, u should have backed this up with pictures now for better understanding.

It comes in different types, sizes, shapes, part number, colour, model and manufacturer. So it will be a big job of over one thousand pictures.

still put pictures for people to see, even if it is just two or three.

Earthing is very crucial but often ignored in electrical circuits.

Op oil dey your head, you are observant.
I noticed this a long time ago during the nokia days with battery wahala, when we had to charge frequently with bad chargers. The issue has to do with the ground so call earth.
I recently found the same issue with my laptop adapter, sht shocks when I glide the metal part of the laptop when plugged in. How to fix?

So is it advisable to buy a charger with 3 pins all made of metals or with the upper pin made of plastic? Please make it clear.

Thanks for this illuminating thread

Educative topic like this should be found on front page not bbnaija, snake, tonto dike, how Buhari snapped pictures chilling with his cows.

Op said, the phones with three metal pins are generally safer than the ones without three pins or with a rubber pin.
For those who didn't go through the post.

Lalasticlala fp pls

In addition to the OP's post.

Electrical appliances with metal bodies should be properly earthed and grounded. The reason behind this logic is that in any case, the Live (Line) wire touches the appliance metallic body, or in case of short or leakage current inside the appliance, and someone touches the metallic body of the machine, current will flow through the human body to the earth i.e. electric shock. This is why proper earthing (grounding) is necessary to protect you and the person who touches the metallic body of the appliance or machine not to get electrocuted.

The earth pin should be the first to connect and the last to disconnect with electric supply. This is one of the reasons why the earth pin is longer than the live and neutral pin on 3-pin plugins.

When we insert a 3-pin plugin into a 3-pin socket, the earth pin is the first to make a contact with the socket as compared to the Live and Neutral Pins. The earth pin is the last to disconnect from the socket when removing the plug from the socket. i.e. Live and Neutral disconnects first and then the earth pin. This way, earthing is well maintained during the operation for proper safety and protection.

Safe, only if your house wiring was done by a qualified Electrician to include a proper Earthing.

lol I used to think the reason the earth pin is longer is so it could press down the plastic blocking the other two pins from entering the socket


Educative thread.

Exactly!

Some electricians just do all the electrical connections without rounding it all up with earthing/grounding

Stop misleading people please, you claim to be an electrical engineer but doesn't know the difference between a conductor and a non conductor, AC currents and DC currents
1.Plastic as used in phone chargers cannot conduct electricity.
So there's no way voltage will get to you or phone.
2. There's a transformer in phone chargers that change AC ( alternating current
..like the current in a wall sucket that can shock) to DC (direct Current..like the current in a car battery)

There's no way AC current @ 220v will escape the transformer that it's supposed to change it to DC 5V and travel through plastic which is a non conductor to the phone or the user.

As for phones electrocuting people , I think the electronic components inside the phones are responsible and not the chargers.

Educative. Informative..

Cownative.

It will help alot
