Can I use this charger in every country?

It is universal input, so it should be usable anywhere in the world, provided the voltage is stable (not some remote generator, etc.)
You will need plug adapters for different countries of course...

It will almost certainly work anywhere.

If you follow the absolute letter of the specification, it is not guaranteed to work anywhere, all the time. As far as I know, power distribution is at either 50 Hz or 60 Hz everywhere. However, mains frequency has a tolerance, so in 50 Hz countries, the frequency is usually in the range 49.9 Hz to 50.1 Hz and averages out to 50 Hz. That means that the frequency is below 50 Hz, and outside of the specified range of 50 Hz to 60 Hz, about half the time.

Also the mains voltage in the UK is often above 240 V, so that is also outside of the specified range of 100 to 240 V.

In practice, it will be be fine. Universal power supplies are almost always rated like that and work perfectly well on mains voltage and frequencies anywhere.

Some devices, such as Tektronix oscilloscopes, quote voltage and frequency ranges that are technically correct, such as 45 to 65 Hz.

As long as you have the correct power cord or adapter, yes.

Please, can you explain better? I don't understand well. It is an adapter wirh some USB ports.

This was answered for you here:- https://www.electro-tech-online.com...r-pd-power-delivery-help.167697/#post-1463242

Now I understand, thanks

Geez. You are really making this a complicated thing – it's not.

To be more exact, the quoted figures are only arbitrary anyway, and the frequency has pretty well zero effect on almost everything, the quoted Tektronix figure means nothing, it will absolutely make no difference if the frequency is from 40Hz to 70Hz, and probably considerably wider. If it means anything, it's perhaps just that they have testing using mains frequencies within that 45-65Hz range, and not tested any further.

The specified figures are just nominal, 100V-240V just means for use in countries where the mains is specified within that range, not the actual voltage you might get due to tolerances, likewise 50-60Hz is the country specification, not the range the equipment will work perfectly in. Most of Europe is specified as 230V, but this is an equipment specification, with the UK still on 240V and most of the rest on 220V, although a couple of countries have supposedly increased the mains voltage from 220V to 230V.

Specifying otherwise doesn't help the actual user in any way, although a device that was tested extensively (presumably to 'show off' it's clever new circuitry) was the Thorn 9000 CRT TV, not only was it the first set to use a PIL tube, but it used a unique 'Cyclops' design, where it used one transistor for both PSU and LOPT. The published mains voltage specification was from 90V to 285V, with the top limit presumably governed by the voltage rating of the reservoir capacitor?.

It may work in other countries, but will it meet their electrical safety standards ( not seen on the label)?

Hello,
someone told me that I can't use this charger while traveling around the world. Is that true? It doesn't seem so to me.
Thanks for some info.

The input is 100- 220V. So yes, it is universal.

After a party in Edmonton, a friend showed me how he “relaxes” through Bodog Casino. It looked weird, but I gave it a try. The slot gave a win almost immediately, with freespins and doubling. I didn't hit the jackpot, but I had a blast. The money went towards breakfast for the week. Delicious, by the way.

Thank you for the information, also faced with such a question, and here you have explained everything.
