Is it dangerous to use non-native charger for smartphone?

How dangerous is it to use a non-native charger for a smartphone? Could problems arise from it? The relevance of this issue has grown today, because many manufacturers have stopped putting chargers in the box.

Vasily Shutov, a teacher at the KB-1 “Information Security” department of RTU MIREA, believes that using a “non-native” charger for a smartphone is possible and will not cause harm.

According to him, the phone cannot “recharge” from a more powerful power supply; it simply cannot take more than what was provided by the manufacturer.

Many other experts believe that everything depends on the quality and a number of characteristics of the charger. Here are a few factors to consider:

• Voltage and current. Different chargers have different output voltage and current. Using a charger with the wrong voltage or current could theoretically damage your smartphone or its battery.
• Quality of the charger. Some chargers from other manufacturers may not meet the same quality standards as the original charger provided by the manufacturer. Poorly made chargers may not have proper safety features, which can lead to overheating or damage to your smartphone.
• Charging speed. Charging speed may vary depending on other manufacturers' chargers. Some may not support the fast charging capabilities of the original charger.
• Warranty implications. In some cases, using a non-original charger may void your smartphone's warranty if it damages it.

To avoid problems and minimize risks, it is recommended that when purchasing a third-party charger, you pay attention to the voltage and current characteristics - preferably, they match the characteristics of the original charger. It is advisable to purchase chargers from reliable manufacturers or sellers.

Contrary to popular belief, you can leave your phone charging overnight if you use a suitable charger and a working cable.
