How to choose the right current for loads?

For example, if the maximum current of your load device is 10A, then choose 10A/0.7=14.28A in any case for resistive loads according to the international standard.

If the load device is a motor or compressor, you can choose 10A/0.5=20A according to the real test result, since the starting current of the motor and compressor may be 2-3 times greater than the rated current.

Product description by manufacturer:

Going abroad? Are you planning to use your computer, cell phone, hair dryer? The PVC series step-up/down voltage transformers provide you with a safe, reliable, cost-effective and convenient solution for converting voltages from 110-120 volts to 220-240 volts or from 220-240 volts to 110-120 volts for both home use and commercial applications. The PVT 320U comes with a power of 500 W, a sturdy power cord, a standard American 3-pin plug and an American to European socket. There are a total of three types of outputs on the front panel. Two are grounded outputs, one for 120 volts with a US standard output. The other output is only for 220 volts with a universal socket. The latter is a 5V standard USB connection. And most importantly, all three outputs can be used simultaneously and continuously. For safety, the manufacturer recommends that the maximum power of the voltage transformer is equal to or greater than the rated power of your appliance multiplied by 1.5. For example, if you have a 100-watt device, choose a transformer with a maximum power of 150 watts or more.
