2. Pros and cons of USB phone chargers

Who doesn’t love the concept of USB ports? It’s universal, it’s a standard and you can find it anywhere. It’s so standard that it lets you connect your phone to tons of different things. There is a problem, however, and this can affect the satisfaction that you get from your USB device. We know that USBs are capable of sending both data and power through the same connection.

The problem is that not all USB ports in the world are capable of doing that. Even if your USB port was manufactured to produce power, the manufacturer’s preferences can get in the way.

3. USB data connection in your car

Most vehicles that are designed with USB ports are designed to transmit data only. These types of USB ports will allow you to plug a USB drive into your car. You can do this to install program updates, play music and so much more. This type of port uses only data connection terminals. That means it can’t power up any peripheral devices – even your phone.

4. Charging cables vs. USB data cables

The USB standard indicates a configuration with four terminals. These are clearly numbered from one to four. The first and fourth terminals are responsible for transmitting power. Terminal numbers two and three, on the other hand, are capable of transmitting data. A lot of the USB cables sold nowadays are capable of transmitting both power and data.

Data cables only have the first and fourth terminal. Power-only cables have terminals numbers two and three. But unfortunately, the system is more complicated than it sounds. For your carputer and infotainment system to provide you with higher charging amperage, a charge-only cable won’t be enough.

Your computer needs to receive a specific command that tells it when to provide the higher amperage. That command could be different depending on your device.

If you need your USB cable to charge your phone, you can short the second and third terminal. This can be found at the end of the cable. This works for a lot of products out there. But Apple has a different way of doing things, so you can’t always assume this will work with their products.

It is, of course, possible to have power-only ports in vehicles. But most of the USB ports that can be found in cars are still tapped into the infotainment system. That means that even if your vehicle does come with a power port, its primary purpose will still be sending data.

There are times when your car USB port not working. Once this takes place, your port may not charge your phone even if it can originally do so.
