I'm afraid you're still not being very clear to us. Are you asking if there is harm to the chargers themselves if they're kept plugged in constantly? If that's your question, then the answer is also no.
If that still isn't what you're trying to ask, then perhaps you could use the Google Translate site to input your question in your native language, then copy and paste the English translation?
Thanks is was that my question means related to chargers
Anywat Thanks Dear
