The most basic reason to use 220 instead of 11o is that for a given load Watts= Volts x Amperes Double the volts and you will halve the amperes. The rating of wire is the amount of amperes it can safely carry. Less amperes means you can use a smaller wire size. This will save money on the initial installation.
it hurts less when you get electricuted? Other than that, not much - just depends on what you're trying to run off of that power supply.
110 volts grid requires bigger number of smaller size of step-down Transformers. Smaller transformers can be placed on a poles. 220 volt transformers are significantly bigger and heavier so they cannot reside on poles and need to be setup on the ground or inside of a building.
This is why you will never see pole transformers in Europe
220 volts require thiner wires, less current and smaller number of transformers.
220 is only preferable on large tablesaws and bandsaws, most other tools will operate perfectly on 110v

"Power" is not expressed in volts, but rather in watts (Volts times Amperes), for instance. So you cannot say whether 110v or 220v is more Power-ful unless you also know how much current (Amperes) is flowing in the electrical circuit.
Yes. If the computer power input is only rated for 110V input, you can power it from 220V by using a voltage converter from 220V to 110V with appropriate wattage. Some computer power supplies also have a switch for setting 110V/220V in which case computer can be powered from 220V after changing the setting. Most of the portable computers/laptops have power adapters which are rated for universal voltage (e.g. my Dell laptop AC adapter is rated for 100-240V 50-60Hz).
If you connect 110V xbox one to a 220V outlet, only the power supply will burn and not the Xbox one.
of course. go to the market and buy a transformer. It will convert a 110V supply to a 220V supply.

Yes it will. The only thing that you have to keep in mind is that in Angola the power is 220V so U'll need a power brick with 220v. Or U can buy a power converter to convert 220v to 110v.
The power-bar must be plugged into the correct voltage it was designed for.
The fact that it's supposed to. Voltage is stated as the difference between the two wires carrying electricity to the load. When they bring power to the house from the utility, you get two wires carrying 110v but they're 180 degrees out of phase. Imagine one carries positive 110v and the other carries negative 110v. If you hook one of these wires plus a neutral (zero volts) to the load, you get 110v--110v over 0v. If you hook both of them to the load, you get positive 110v over negative 110v, or 220v. So...red to white is 110v, black to white is 110v, red to black is 220v.
At 20 amps the 220V will supply twice (2x) the power that the 110V will supply. The answer depends upon your meaning of the term 'better'. If you have a specific size load that you are supplying such as a motor that will accept either 220V or 110V then by using 220V you will have less of an impact from voltage drop and the conductor size will be smaller due to the current being 1/2 of the 110V. If by better you mean which one will give you the most power then the obvious answer is 220V.
Use a transformer to lower from 220 to 110V.
Do not do this.
