The world is not just divided into rich, developing and poor countries. There are numerous differences, o in the case of electrical voltages. Much of the American continent uses 110V voltage, while Europe, Asia and Africa are 220V. In Brazil, it could not be different, the situation is more complicated due to variations between states and municipalities, that is, there are places that are 110V and others 220V. Therefore, it is not uncommon for people to lose equipment by not being informed about it, especially when traveling, whether for work or tourism.
Although many devices are bivolt, it is always important to know the main differences between voltages. After all, not everyone has this technology.
Discover the main differences between 110V and 220V
The main difference between the two most voltage ones in the world is the power current. At 220V, a smaller current is needed, and may have thinner wires. Already at 110V, now 127V, uses a greater flow of current.
In the end, consumption is measured in kilowatt hours. So, the average doesn't change much in relation to the cost to the consumer.
Understand why appliances burn out
Based on the existing current at each voltage, the premise is mathematical: 127V appliances connected to a 220V outlet burn out. Otherwise, no!
That's because it will flow a current greater than it can handle. In the case of 220V connected to 127V outlets, the only unusual situation is that they will be operating at reduced power. Therefore, always check the voltage of your equipment before plugging it in, wherever you are!

Bivolt X Autovolt
Devices with bivolt technology work in both 127V and 220V, but be aware: there is usually a pin for you to adjust the voltage, according to the outlet. This happens, for example, in hair dryers.
Autovolt is the technology used in chargers for smartphones and cell phones, notebooks and various computer equipment. The system works between 127V and 220V and adapts automatically, recognizing the electrical voltage.
