Car chargers are a must-have for car owners in their daily travel, and they are familiar with most car chargers. The following are most of the misunderstandings DAMAVO ® has sorted out for you when choosing a car charger simple fast charger, 12v car adapter to USB, USB phone charger for car or using it.
1. The car's built-in USB can directly charge the USB
Many cars have USB ports, and there may be more than one port. But these USB interfaces are not used to charge mobile phones, but to transmit audio data, so the interface current of most cars is only 5V/0.5A charging current "more or less". If you use the USB port on the car to charge a mobile phone or tablet, the current will not meet the standard, and the device will be damaged. So, first of all, the car owner should first understand and be familiar with the main purpose of the USB interface on the car.
2. The more USB ports, the slower the charging speed
The current depends on the voltage, not the number of USB interfaces because the current is already divided when the manufacturer manufactures and does not interfere with each other. Imagine that if it is slower than a single USB interface, there will be no market for chargers with multiple interfaces. Which customer will buy it? Manufacturers design multiple U ports, mainly to facilitate car owners to charge multiple electronic products simultaneously.
3. Unplug the car charger after turning off the engine.
Currently, most of the car's cigarette lighters are powered by ACC instead of constant power, which means that the power can be cut off when the car is turned off. This is a safe practice. Even for models with uninterrupted power supply, the onboard charger generally has no current output when it is no-loaded. Even when it's not unplugged, there's only a tiny LED light working, and the drain on the battery is negligible.
4. Not knowing the maximum power of the expansion port
Many small devices in the car need to be powered by a cigarette lighter, so many people will buy a car charger with a cigarette lighter extension. However, some say that the same product is easy to use, and others say that the fuse is blown. This is probably because the device exceeds the maximum power of the expansion port. Especially car refrigerators and car vacuum cleaners have high power. So be sure to look first. What is power? See if your car charger's expansion port works. This information will usually be marked on the box or manual if you buy a regular brand through regular channels.
Therefore, the most important thing is that when choosing a car charger simple fast charger, 12v car adapter to USB, USB phone charger for car or using it, it must be used correctly in the way the manufacturer requires it to avoid serious consequences caused by improper use.
