A Few Reasons to Not Charge Your Smartphone in the Car
We get it — you’re busy and need to stay in touch with family, friends, and coworkers during the day. Sometimes you just need to plug in your phone to a mobile charger, via the USB port in your vehicle. Here are a few reasons this habit could do more harm than good — for both your phone and vehicle battery.
Too much power
According to Brad Nichols, a technician at Staymobile, most phone chargers use 1-3 amps. The average cigarette lighter port, however, supplies up to 10 amps. This could result in too much power for your smartphone, which could overheat the phone or damage some of the phone’s internal parts.
Not enough power
By contrast, the USB port in your car might not provide enough electricity to sufficiently charge your smartphone. When you’re commuting to work, from example, you might notice that your phone didn’t charge (or charged just a little) during the drive. As Nichols articulates, “This is mostly due to the fact the phone is using more power than the car charger is supplying it.”
It can drain your vehicle’s battery
Per Nichols, if you have a newer vehicle model, it might be safe to charge your phone during the drive. However, if you have an older vehicle model, it’s best to avoid charging your phone via the USB port since this can drain the battery.
