220-250 Volt, as is the main part of the Europan Community.
If the device you are powering requires 7 amps of power, then no. You will need to find a replacement cord with 7 amps. Check the power input requirements of the device to find out.
No.
Yes it can. It's close enough to the laptop's power requirements to charge it.
Yes it is close enough. As long as the power supply ampere hour rating is as high or higher than the laptops requirements. Make sure the polarity of the plug is correct also.
No. The volt ampere (V.A) is the unit of measurement of apparent power. Power factor is true power (expressed in watts) divided by apparent power (expressed in volt amperes).

no
No, that is too much.
Power requirements are measured in KVA, which stands for Kilo-Volt-Amperes. To calculate the amount of power you require you would use the following formula. KVA = Volts * Amps / 1000
