What is the buying guideline with regards to wattage?
Ans: Buy a voltage converter with wattage higher than the wattage listed on your appliance. You should always run your voltage converters at 17% ~ 80% of their rated wattage capacity – never exceed 80% if possible! Please make sure not to run any appliance with wattage higher than the wattage of your voltage converter. This might damage both: your appliance and the voltage converter! Q6: Can I use several appliances at the same time on the same voltage converter / transformer? Ans: Yes, as long as the total wattage of all appliances does NOT exceed the wattage capacity of your transformer/converter. If you want to run multiple appliances, run the transformer at 80% of its wattage to avoid damaging your appliances by power fluctuations. Q7: Are grounding and fuse useful or just waste of money? Ans: Grounding and fuses provides additional safety protection – they protect against accidental electrical shock and damage.
