    If you have a device which is rated for use with a 220v supply, than that is the supply voltage you need.
    It will probably still work with a slightly lower supply voltage, but a significantly higher voltage is likely to cause components to break down.

    "Electricity" is a meaningless term. If you need 220 volts to power a device, then you must find a power source that provides 220 volts. What exactly are you trying to do?

    Note that your post falls dangerously close to being substandard, so please put a bit more effort into explaining things and making your posts understandable. If English isn't your first language then you may want to get someone to help you.

    Yes this certainly is a very vague question. I could say that about 24 nine volt batteries such as used in a smoke detector will get you pretty close to 220. It satisfied the question yet is quite likely impractical for anything useful.

    What we have here is a failure to communicate. It centers around the term 'electricity'

    Does your confusion relate to energy, power, current or voltage ?

    Most members who have been banned are still able to login and read the forums, and send and receive some PMs, they just cannot post.

    Apparently.
