What happened to this power adapter?

I know this is not a forum about electricity, but I can’t think of any other place to ask on, so feel free to point me somewhere else. But my question is about a home appliance, so I thought why not?

My question is about the pictures below, a power adapter that “exploded” and turned into everything inside and the wall socket it was on into black. Why could have happened? It was bought on aliexpress.
It was being used with a wize-cam, which original power adapter was of 1A, as this one was too. In fact, it worked for months before it “exploded”. It is located on the kitchen, not sure if it makes a difference.
Please take a look at the pictures below.

'Nuff said.

Is it certified for wherever you live?

It has the CE logo, which in theory signify that products sold in the EEA have been assessed to meet high safety, health, and environmental protection requirements.
But it can be just a couple of letters printed on it…

I would start to guess with poor quality and you would need to dig and find out what exactly exploded, it is all black to me…possibly shortcut from humidity as you stated ‘kitchen’ so slow build-up?? I am not sure if it is worth spending a lot of time on it. I would however be concerned with no fuse response…this is a possible fire hazard



Also don’t dismiss fraud. Anyone can write CE on a piece of plastic, but where is the actual proof of testing.

Yeah…well… not sure if you can trust these…fake stuff is still for sale on Aliexpress

That means very little in the U.S. Their systems are terrible.

Here’s a classic example:
For electrical equipment installed in what we call a ‘hazardous area’ which is one that contains an explosive atmosphere (ie: gas / coal dust) then all countries other than the U.S. require a 3rd party certification company to check the equipment before it can be labelled as safe to install in those areas… in the U.S. they have a system (which is not accepted anywhere else in the world because it’s rubbish) whereby the manufacturer can self-certify the product. Sounds dodgy right? Yep.

My guess would be a surge arrestor or capacitor popped, or as we call it ‘let the smoke out’ (unfortunately you can’t put the smoke back in :rofl: )


In Holland we say Goedkoop is duurkoop.

Something like Bought cheap, got cheap…

Yep, we say ‘you got what you paid for’.

Yes, that’s probably it

Nor I will spend the time to push all that smoke in :grin:

Yeah, probably not worth it. I was more worried about why did this happen, and could happen again to a more expensive (and hopefully better) power adapter?

Nice information, thanks

On the other side of the answer is that sometimes things just fail.

If not I wouldn’t have a job as an industrial electrician.

It’s not always about cheap parts or shoddy quality control. Sometimes it’s just a disturbance in the quantum vortex. :laughing:

But that said I agree with the above - most times you get what you pay for.
