chargers burned out?

Agreed. How much does it cost to learn to use it intelligently?

Both of those should be fine. Even on 250 VAC they should be fine. I suggest you buy a cheap digital multimeter to go further with this. I would check out the socket - and the adaptor you used.

out

have

240V

true

I'd expect any damage to have stopped at the chargers myself. Fingers crossed !

If the company making them cut the iron to the minimum that's very true.

*Very* unlikely.

All 60 cycle transformer power supplies I have tried died on 50 cycle. 120 volts 60 Hz runs OK on 100 volts 50 Hz. However these are SMPS so no problem there.

About $5 or $10 here. When I think what I paid . . . . .

somewhat.

First off if the original powerpack was 5v voltage-regulated, you should replace it with a 5V regulated one, and meet or exceed the current capacity ("amperage").

If not regulated or unregulated doesn't matter much. and 4.5V 0.8A unreguated might work, and will most likely do no damage...

If there's a 5V 1A or 2A regulated supply, that should be fine, this type of powerpack is often used for USB hubs.

Either they lied about 100-240V or your power there in cyprus was more than

240V. I'm guessing that it's the former, I've heard of people from the land of 110V having their 100-240V devices burn out when they travel to the land of 240V, it's possible that some manufacturers ship weaker devices to places that the think have 110V and they didn't realise that cyprus is in europe.

If they sent you an adaptor with a US style plug it may have not been designed for 240V... (US plug is 2 parallel flat pins )

It's most unlikely that the plug-pin adaptor did any damage. a scenario copuld probably be dreamed up eg if it had a diuode in it like the adaptors for some travel irons... but if it is just metal and plastic there basically no chance of it causing damage.

a loose neutral could push the voltage one the least used phase up... this doesn't happen very often.

I'm guessing the cellular charger atleast 5V regulated (which is the same as USB) in which case it failine with an overvoltage output is unlikely.

probably.

Only if they are 5V regulated.

You have a lot of faith in the intelligence of those who gain random access via the internet. Just as an aside, how will a DMM help detect anomalies in household electrical service?

If he has 400 VAC across the outlet that would indicate a slight problem.

test the voltage with a meter in that same socket. then test from a ground point to each input of the socket.

But it wouldn't show damaged contacts, or a loose connection, just that there was a voltage at that moment.

No, that would indicate a big problem, in which case the services of an electrician would be imperative.

That was irony. Having two phases on such an outlet is a bad thing.

If it helps, I put a lamp on that socket which did not show any fluctuations in luminance. But then again a lamp is not as sensitive as a charger. Anyway Voltage quite more than 240V would burn the lamp.

That's a valid test. Also, whatever adapter you used wouldn't increase the voltage. It looks like bad luck.

I would buy an adaptor that has 3, 4.5, 6, 7.5, 9 volts out (say) and start off at the lowest voltage and increase as needed. Be sure to get the polarity right.

By the way, you didn't accidentally use the wrong charger on the right device did you?

I bought Ideal - also good.
