Charging phone and laptop batteries in cars can cause fire and explosion

Many people often do not worry much about charging their phones or laptops, because these vehicles are equipped with sockets. However, there is an important information that many people do not know, which is that the electric current in the car is a direct current supplied from the battery. Therefore, if you pay attention, you will see that the time to fully charge the device is longer than when we charge at home and it also has a higher risk of fire and explosion due to the phenomenon of electrical impulses.

Electrical engineers advise families to equip themselves with their own charger specifically for the purpose of moving vehicles. It has the ability to convert DC current into 220V AC current suitable for all devices and also limits the risk of fire. However, people also need to pay attention to some things when using a converter charger.

General notes when choosing and using chargers

Similar to when at home, charging the phone in a car or train should not be used while charging to avoid causing an electrical surge that can damage the device and endanger the user's life. Especially the power source in the car is unstable, so everyone must be very careful.

Charging a phone or laptop on a train or car is usually longer than charging at home. For example, if it takes 1 hour to fully charge the battery at home, it will take about 1 hour and 30 minutes when using a charger connected to an outlet.

Finally, you should learn the details of the charger you need to buy to choose the right type for your phone, laptop in the car, train. In addition, you should buy at reputable supermarkets and stores with warranty.

Note for phone charger

For phones with keyboards: Choose a charger with a power capacity of 500mA-1,000mA.
Smartphones, touch screens: Choose chargers with a power output of 2000mA – 2100mA.

Plug the charger directly into the power outlet on the vehicle. Do not connect indirectly through other outlets as this can easily cause an electrical surge that could burn the device.

For cars, each type of car will have a different power source, so people should pay attention when choosing the right charger. Most cars today only need to use 1 - 2A for cars with 12V voltage.

Notes for laptop chargers

Choose a charger with a charging head that fits your laptop's charging port.

You must know the voltage information of your laptop to choose a charger with the appropriate voltage. Specifically, read the power information printed on the device's charger to determine the voltage level.

When you plug the charger into a car or train outlet, the red LED will light up to indicate that the device is receiving power.
