What surge and USB protection system does the 10$ power strip have?

Quite possible. This cannot be ruled out./quote]


Why? Because the "outside" is the casing, while inside you can put anything and it will look "the same".

The Chinese can make anything, whether it is a good thing or a cheap thing. It is just a question of money. This skirting board is a product from the CCC category = Price Makes Miracles. Is it supposed to be cheap? It is cheap... and majfrids specialise in tuning products with their technical specifications. The description is not what the skirting board gives, but what the user would like it to give (at that price).

One other thing to look out for in this strip - the connection between the PE pins and the brass plate.
It's a poor quality riveting, some of the pins are allowed to rotate freely, which means the electrical contact is poor. Let corrosion or dirt get in there and then the PE on the receiver is gone.
You can try to solder it solidly, but that too can get pitted, cracked etc after time.

As I started to read the specifications in the picture, I felt a thrill of excitement.
Numbers, stamps, standards....

It looked like a power strip from NASA.
And it was colourful. Luminous. The only thing missing was a fan.

Upon opening it inside - I saw a gie.
But still colourfully wrapped.
A lovely colourful gie.

That's what scares me. Because it all looks so very professional that one wants to believe it's safe and well made.

Well, we eat (and buy) with our eyes.

PS: comment by colleague acctr - very important. Such a marvel seems to be safe - because it's pretty. And it's playing with fire or death.

(That's why I prefer my old strips bought in the 90s - solid so that you can hang on to them; and a strip made by my Dad from separate solid sockets with solid screw terminals. Just need to add a varistor and it will be 'cool')

It's a bit ridiculous to consider a £35 skirting board. What price, such a strip. Before the pandemic I bought 3 such strips, I paid 25 zł each. You can see from the price that it's not for serious use, just as you can't count on any protection. I use the strips to switch on devices with a power consumption of a single watt, and here these switches work superbly. In one socket strip out of three, the "earthing" pin broke of its own accord, after a year of use. This skirting board is a normal skirting board with higher functionality in the form of these switches. Some engineering considerations, visions of fires, are probably a slight exaggeration. No one with a basic knowledge of electrics would use this strip to power equipment with a consumption of hundreds of watts.

And not having this knowledge, he will apply because the description of the strip reads: Maximum load 2500W .

Look at the reviews of those who bought this crap on allegro, extensive photo documentation, wires hanging loose, live fixing screws, etc.

Information is missing whether the load is continuous or instantaneous .
I once asked a salesman about this he boiled it down, but the boss came out of the back room, checked and informed.

If instantaneous, it should be PMPO.

There will be nothing here, but by the way, it's hard to expect decent workmanship for this amount.
There are similar slats around £100, but I don't know how they are made inside.

these identical strips show up every now and then in chain stores like Biedronka .

...and in one such promotional offer there was even a strip available without a varistor (I checked it myself). That is, such a cheap coloured extension cord. As for the "quality" of the cable too - tragic.

I am satisfied with mine bought at Biedronka about 4 years ago

Take a look inside. Maybe you have the "unprotected version" too?

LEDówki wrote:

Reporting to the OCC will not take this off the market?

Rather not. Even if it disappears in the big sales chains, the bubble will appear in markets, online, etc. What is imported must sell .

I'm surprised that people haven't learned to distinguish between a bubble and a decent appliance. This is actually basic life knowledge. Just as people had to distinguish between edible plants when they were collecting, now you have to be able to distinguish between "usable" things. I have a strip made by a Polish company. It has worked for over 20 years. I have dismantled and washed it twice and replaced the cable once, because it had become stiff after several years. It has the right (it seems to me, I haven't analysed the elements) protections.

I recently bought a power strip Made in Poland, unfortunately the strip riveted and the plug flooded.
To assess its quality it is necessary to destroy it.
I'm not convinced that if something was of good quality 20 years ago, it should be the same now.

You can't tell if a trim is good or bad without looking inside. More and more often they are riveted together with strange screws. Just because a skirting board is labelled "Made in Poland" does not mean that it is made in Poland and that it is hyper cool.

It is simply not possible for everyone to learn everything. Especially people who don't have the technical knowledge, they just want to buy a product and use it. And they rely on the manufacturer's and distributor's description or on reviews. So the only problem is that someone allows junk products into a (supposedly!) safe and scrupulously controlled market and someone tolerates misleading customers. And this in a situation where we have (again supposedly) the best consumer law in the world. Where margin is left for bubbles, they will simply appear. And the tolerance for fraud makes it a problem. Therefore, the customer is not at fault here. He has the right to expect, for his money, that which meets the declared requirements and standards and presents an appropriate quality. Supposedly European?

The fact that a particular strip has the label Madein Poland does not yet mean that it is manufactured in our country and it is hyper super.

Exactly! Plenty of cheap Chinese bazaar-market equipment is precisely "Made in Poland". Because in our legal reality, all that is needed to make it "Polish" is a label and a distributor's logo on a mass-produced product imported by containers from Asia. Anyway, the bubble described here is also offered as "Polish". But I have also come across one offered under a "German" brand. Surely it is even more robust? .

Nowadays, "reviews" or "description" is pure marketing i.e. a scam all the way. Unfortunately, most consumers believe these descriptions or opinions. Nobody is interested in the niche, thinking customer because it is the non-thinking customer who generates turnover.

I don't know if you have heard of conditioners from the Voodo audio world.
They are LC filters and surge protectors. Apparently you can make your own and it can work.
Appropriate varistors, filter circuits that limit everything but 50Hz.

Here something from the web"


Herea something from the US (for 120 VAC, but could probably be converted):
.

Is it with a varistor:
.

Over time this will probably become a necessity - more and more devices with switching power supplies will interfere. Who knows whether energy suppliers will not measure the harmonic content on the consumer side and thus impose the necessity of fitting filters in the form of surge strips with filters or something like audio conditioners.

Yes, supposedly the effectiveness of these solutions is higher than an ebony cabinet enclosure and platinum feet screwed together with palladium-infused screws....

Who knows whether they will not shoot themselves in the foot in this way. More and more people are increasingly complaining about Big Energy. People are simply fed up with the overpricing, the diktat or the lack of reasonable alternatives. Someday this bubble will burst .

This has to break - I wonder what would happen if they didn't need to buy energy like that .
Youngsters can't cope without a smartphone, addicts on TikTok or another Instagram too....

It would be the end of civilisation...

There will be no end of civilisation.
Ups and downs are nothing unusual that we know (should know) from history.
But we learn from history that we do not learn from history.
After the currently imminent collapse, humanity will also rise and there will be another leap in civilisation.

That's for sure - the question is whether it will be as someone once said:

"I don't know what World War III will be like, but World War IV will already be on the mace" .

If the historical truth is Atlantis and the mythical vimanas (flying machines) then humanity has not yet recovered from the last collapse, and here is another one on the doorstep ;P

sq3evp wrote:

Probably yes. But it is certainly possible to charge a laptop, smartphone or tablets from solar installations. The end of the world is therefore unlikely to come from this. What brings us much closer to collapse is our progressive dependence on technology and the increasing challenges that have been known for decades. And 'progress', instead of actually moving humanity forward, usually ends up with yet another generation of useless gadgets that only exacerbate these problems.

The word "if" seems crucial in this case .

Tell me, please, why should you charge your laptop if all the electronics are likely to fail after a nuclear explosion?
Are you going to watch old films?

For now, the war is going on several fronts - green energy and ideological, maybe even stemming one from the other.
A real war using nuclear weapons is the end of the story - it will be survived by a handful of VIPs who cannot cope without the rest.

The external appearance is beyond reproach, and people do not have the sense or some portable device to even look inside the case.

Correct.

The control of the market is in practice, for the most part, passed on to consumers.

Forgive me, but a nuclear attack is really quite an offtopic already .

Exactly. This trim looks normal and gives the impression of a functional device. So it is difficult to expect detailed technical analysis, let alone advanced research, of a simple and cheap product from the average buyer. Quite simply, no one has the capacity to do so. All the more so in a modern civilisation that adheres to the "throw away and buy new" religion .

Mobali wrote:

Why? Then the safeguards may not work out;) .
This is extreme, but not out of the question.
For residual disturbances, impulses etc. etc. such a strip may help.

A nuclear attack is not that simple because every attacker expects a similar response.

Albert Einstein once said that the Fourth World War would be for machetes.

Topic very interesting. But better to set up a separate thread for that purpose. This one, however, is about something else. You might as well consider the invasion of the Huns, the landing of a UFO or the fact that the sky will fall on the earth tomorrow.

Exactly - and in reference to the topic:
A strip for 45 PLN cannot have good protection, maybe if you add 100 PLN something could be found on the market.
On the audio forums, for example, the following strips are described:
Brennenstuhl Secure Tec .

This skirting board I have written about is a Lestar LFT 2001, and I am not writing as an advertisement. I've only now checked what kind of skirting board it is, what manufacturer. But they write that there are protections in them and there are. And it costs more than 45PLN, because it has to cost.
