You have a long car trip ahead of you, so naturally you’re going to turn to your iPhone to provide a source of entertainment. Listening to music from your iPhone, or at least having it charged in case you want to make or receive phone calls, requires a solid way to actually charge it while you are driving.
Unfortunately, charging your phone in your car isn’t always so simple.
This is the one thing you should never do when your iPhone is charging in your car.
The one thing you should not do when you’re charging your phone in your car is the one thing you probably think you should do: use your car’s built-in USB charger.
If you have a newer car, its manufacturer was probably kind enough to include a built-in USB charger. But the charger isn’t always going to live up to your expectations.
According to How-To Geek, built-in ports are “anemic when it comes to amperage.” In other words, they simply don’t deliver the powerful charge needed to support most modern devices.
Your car’s built-in USB cable will charge your phone — eventually. But if you’re in need of a fast charge to get your device ready when you reach your final destination, there’s a much better solution (and, yes, it exists in your car).
Using your car’s 12v ports instead of the USB charger is a more effective way to charge your phone, according to How-To Geek:
“Give up on the built-in USB ports and harness the power of your car’s 12v ports and some universal chargers—the 12v port on most cars is rated for at least 10A, which means there’s plenty to divide among your devices.”
It’s equally important not to overlook the type of charger you’re using in your car.
“A good plug-in USB car charger can offer more charging goodness with 3-4 2.1A ports than all the built-in ports in your car combined,” according to How-To Geek.
If you’ve noticed your phone takes forever to charge in your car, make sure you’re using a quality charger, switch up ports, and try, try again.
