Charging your phone in your car is something you have probably done and one that you consider as necessary, especially when you’re on a long road trip or stuck in traffic during a daily commute.
At first, it may seem harmless to plug your phone into your car’s USB port, but overtime, it could spell disaster. Unless you are desperate, charging your phone (especially an iPhone) using a car charging port might be a big mistake.
You are most likely wondering Why? For starters, the USB port in your vehicle probably provides less electricity than your phone really needs to charge. The result of this is that there is a likelihood that your phone will stall while charging or even fail to charge at all.
There is a possibility that you have noticed that between a 30 to 60 minute commute that your phone charged very little. This is mostly due to the fact the phone is using more power than the car charger is supplying it.
Furthermore, your phone could receive too much power, especially if you’re using a “Cigarette Lighter” port to charge up. Most Cigarette Lighters can supply up to 10 amps, while most chargers use one to three amps.
A malfunctioning or damaged charger can provide inconsistent power to the device, resulting in sudden spikes or surges that could cause overheating, damage to the internal components, or on the rare occasion, destroy the device.
More so, charging your phone while on the road could drain your car’s battery, too. If you leave your car running on “accessory”—where your engine is off, but you still use the radio, yourdevice will draw power from your car’s battery as it charges.
This may not be much of a big deal if your car is new, as it has a healthy battery. For people who own older cars however, you might want to avoid charging your phone through its USB port.
Most importantly, it’s not safe to use your phone while operating a vehicle. Anytime your hands leave the wheel or eyes leave the road, it becomes incredibly dangerous not only for you, but for the other people around you.
Finally, it is important that you remember to play it safe. If you can, wait till you get home to plug your phone in. Safety first as always.
