First of all, the default current of a 100W 12V generator is 8300MAH. The 8300 MAH is 8300 mA, which is read in milliamps.
The rated current of a 100 W 12 V generator should be 100/. 12 = 8.3 Ampere is 8300 mA
The current in the circuit depends on the resistance of the circuit and the supply voltage. Changing any of them will affect the size of the current in the circuit.
But the output must be. An 8.3 A generator produces a current of 14 A. The heat generated by the generator will increase and there is a risk of burning.
Electrical power = current * voltage
p>The transformer can only be used to increase the voltage. Increase or reduce the voltage if the power supply remains unchanged, if you want to increase the output current, you can only reduce the output voltage if you want. to obtain a current of 14,000 mA and the generator power remainsunchanged, the voltage must be reduced to 100/14= 7.1 volts
If a transformer is used, the conversion efficiency of the transformer cannot reach 100%, usually around 80%, so the power will not increase and will be lower than the original power
