The ampere rating of wire would depend on the diameter, length and usage of wire for specific purpose. Without additional input to the question. it will be hard to give an accurate answer.
Need to know what the amp rating of the plug is, as there are different configurations for each amperage. Check out the chart on related links.
5.1v is the Voltage, You need to also look at what the Amperage rating is on the charger. 500ma, 1000ma, etc. How many Milliamps?
Wattage = voltage x amperage. Every appliance in North America is built to work at 120 V, so you have the voltage. The amperage rating is probably written in the microwaves manual if the wattage is not. Remember the amperage you put on a circuit can't be more that 80% of what the wiring is rated for in the branch circuit.
Larger wires will not reduce the amperage draw of a device. Limiting amperage draw is accomplished by fuses wich blow when the amperage drawn across them exceeds their specifications.
I doubt if the 125 amp breaker will fit into a 100 amp box. This is due to the rating of the box only being rated at 100 amps. If this exchange could be made then the service conductors feeding the box must be upgraded to take the 125 amperage that the breaker will allow on the conductor.
It is ok to use a fuse with a higher amperage rating and not ok to use a fuse with a smaller amperage rating why?
The size of the conductor is in direct relation ship to its rating capacity of carrying a current. The larger the diameter of the conductor the larger the amperage rating capacity of the conductor.

Usually the current rating for a circuit is higher than the current usually taken. This leaves a little margin for safety.
No, a fuse of a higher amperage rating will not usually have a higher melting point link. The higher amperage fuse will use a wider link or a link of larger diameter.
600amps
The amperage rating is dependent upon the insulation rating. A pair of 25mm squared wires touching each other are rated at 131 amps. Three 25mm squared wires touching each other are rated at 110 amps.
If you want to operate the conductors maximum capacity, the conductor needs the heat, that the amperage produces, to be dissipated. This is why in the electrical code book there are two amperage ratings. The first one is for a free air rating which allows for a high ampacity of the wire. The other rating is for three conductors in a conduit which confines the cooling capacity and so the ampacity rating of these wires is lowered. The same procedure is used in cable spacings in ladder tray networks.
