i have one transformer, but i don't know what wattage does he haveso can someone help me with that
If the transformer has both the voltage and the current or amps listed on it just multiply the two to get wattage. A 110 volt transformer at 5 amps will be 550 watts. If the transformer doesn't list both of these specs, try looking up the brand and part number to see if you can find them. That would be the only way. A bigger transformer will generally have a higher wattage rating but you won't know exactly what the rating is.
