Usage of USB car chargers is on the rise these days as people are getting busier and do not have the time to sit around and wait for their mobile phones to charge. The need to charge without wasting time gave birth to devices like power banks and battery cases. However, power banks had limitations: they are too heavy to carry around, take up much space in the luggage and require the usage of wires which makes their use a tedious job.
Battery cases seemed to have solved the issues which power banks had, they were lighter than power banks, took lesser space and did not require the usage of wires. However, they came with strings attached too: they made the mobile look thicker and ugly, they heated up the mobile phone’s battery when mobile phone and the case were charged together, and they made the mobile phone heavier.
USB car chargers are a winner concerning the drawbacks of both the devices as mentioned earlier. USB car charger is an electronic gadget which can be plugged into the car lighter port and the electricity gained can be used for charging mobile phones. However, concerns are raised over the issue that are USB car chargers safe to use?
Safety is and should be, the priority amongst most people today, especially when using electronic items. Now, when a charger is plugged into the car’s lighter port, suspicions begin to rise. The reason being that the place is for the lighter and several people think that the port has the potential danger to set the charger on fire too which is not at all sensible. However, there are some inherent dangers of USB car chargers, and we will be discussing them here.
First of all, the port in your car is for the lighter and not for charging your mobile phones, so it might not be capable of providing such a high amount of power (wattage or amperes) required to charge your mobile phones. This would not only charge your mobile phone slowly but will also cause long-term damage to your mobile phone’s battery.
Your mobile might also barely charge at all if the power is not enough. On the other hand, some ports are designed to supply as high as 10 amperes of power, but most chargers use much less than that. A malfunctioned charger might not be able to provide consistent power, leading to spikes in power and this would cause long-term damage to the mobile’s battery in addition to a chance of explosion and fire.
Secondly, charging your mobile phone using car charger might put your car’s battery under risk too, especially if the car is too old. If you regularly charge your mobile phone using the car charger while the car is on, but the engine is not running (accessory mode), you should stop right away, because this drains your car’s battery.
Moreover, even when the engine is running, some old cars’ batteries cannot bear the load put on them and might start draining. If your car’s battery gets drained, the car will not start at all until the battery is charged again using external chargers.
As far as the fire is concerned, there is not a very significant risk of one until and unless you are using low quality or malfunctioned charging equipment. A charger made with a low-quality plastic might melt due to the heat caused by charging and would start a fire.
On the other hand, a malfunctioned charger that is unable to keep the power consistent, might cause spikes in power it supplies to the mobile phone and supply of a high amount of power suddenly, might cause a battery to explode or catch fire. So, conclusively, a USB car charger is safe to use up till you are using good quality charging equipment, and your car’s battery is capable of bearing the load of a mobile phone charger.
