Whether automotive or induction, smartphone chargers and tablets are included in the daily routine of Brazilians as an indispensable item. Each model works differently, but their safety is due to the quality of the internal components and the design of the charger, which helps prevent short circuits and overheating.

Chargers must convert current first

The first important information for understanding the operation porters is that devices are not mere extensionsbecause they need to convert the 127W or 220W Brazilian outlets into the 5W or 9W currents supported by the batteries. ”O Charger there are four important steps to take with the internals, and the first one is step-down moduleresponsible for the transformation of this chain,” emphasizes Gustavo Massette, Product Manager at Positivo Tecnologia, the company that represents Anker, the accessories manufacturer, in Brazil.

Then comes into play Straightening systemwhich eliminates the negative part of the frequency, creating partial direct current and prepares the equipment for the third step: Filterwhen, in fact, the energy coming from the outlet is transformed into D.C.. The fourth and final step is to Regulation, moment that guarantees the safe charging of devices from a source of constant power to a cell phone or tablet under voltage.

Inside the chargers there are circuits consisting of semiconductorswho need space to function correctly and safely, without overheating. “Usually, semiconductor used siliconand offer the user a compact charger, considering the energy loss in the form of heat from this material,” explains Gustavo.

In addition to the internal constitution, another fundamental part porters (except induction) is the cable responsible for transferring power to a cell phone, just like a bridge connecting two sides. Gustavo emphasizes that the consumer should always check the quality of the material used in the yarn, including from information such as the number of times that can be doubled and the warranty period. “Among the strongest cables, we can mention cables made from aramid fiber and wrapped with strong materials such as nylon, PVC or TPE,” says Gustavo.
