If you want to absolutely use your electric shaver in the US, you are looking at spending about $30 for a step up/step down transformer or a special travel adapter for the same purpose (usually has a lower wattage rating). An induction cook-top for instance will almost never support cross voltages. Sometimes, smaller devices such as electric toothbrushes, electric shavers, curling irons, hair dryers must be checked as well. Devices with a higher wattage requirement (>500W) typically do not feature cross voltage usage due to a requirement of larger power supplies. You should do this check for any electrical device you wish to carry. An example of how this is written is shown below. The best way to make sure is to check on the device or its power supply. Unfortunately for the electric shaver, you are stuck with 220V.


Your electric shaver on the other hand may not be able to handle the different voltages and will not work in the USA. Your laptop and phone chargers are designed to operate at a voltage between 100 - 240 V.
