Is It Bad To Leave a Car Charger Plugged in All the Time?

As more features are added to your smartphone every day, you'd expect their battery capabilities to keep up. But that's not the case! Compared to current smartphone technology, battery capacity has hardly risen in the previous five to six years. 

As the use of applications increases, their drain on your smartphone battery grows. Many people are now unable to survive a whole workday without charging their iPhones.

That's why a car phone charger is an essential car accessory nowadays. It keeps your iPhone or Android smartphone charged on the go. However, a fear might creep into your head when you connect your phone to your car to charge it up, especially when your vehicle isn't running. 

The voice murmurs, "Is it bad to leave a car charger plugged in?", "Can a car charger drain your car battery?" The short answer is, "YES." However, you need some electrical knowledge to digest this answer. And this blog post is all about it. 

Car Charger Plugged in

Is It Bad to Leave the Car Charger Plugged in?

It depends! On what? On your car charger outlet. There are three categories of car charger outlets your car may have:

  • Always on: Even if the vehicle is switched off completely, your gadget will remain powered. As long as the vehicle's battery has juice/connections, it will stay hot and fully powered.
  • Delayed off: If you have a Mustang, you may see this. Your charger will stay on for 90 minutes after the vehicle is shut off. Then it will turn off if you don't come back.
  • Always off: In this case, your phones will remain powered only when the car is running. When you depart the vehicle and switch it off, the electricity to that socket will be automatically turned off.

You don't have to worry about plugging it constantly in if you have the Delayed Off or Always Off kind of car charger outlet on your car. 

Most car chargers have a light that indicates when the charger is plugged in and receiving power. When this light is on, the charger uses a small amount of energy from the plugged outlet, which isn't safe. If your charging lights go off as you unplug your phone, your phone, and your car is safe; no worries. In other cases, you should unplug the charger every time. 

Leaving a car charger plugged in when you're not using it is also a waste of energy, but not a huge one. The charger will draw a small amount of power from the outlet to power the charging circuitry and the LED light. This power usage is so small that sometimes you may feel that it's not worth unplugging the charger when you're not using it. 

When Should You Unplug Your Car Charger? 

So, the question arises, when should we unplug our car charger so that it won't hurt any gadgets? 

You should unplug a car charger from the car charger outlet if you're not going to be using it for an extended period. If you know, you won't be using your car charger for a week or more, unplug it from the outlet. This will help save a small amount of energy and keep your charger from wearing out prematurely.

Can a Car Charger Drain Your Car Battery?

Yes, charging your phone while driving/not driving in your car can drain your battery. Charging your phone via your car is "just energy transfer from your car's battery to your phone's battery." So, if your car battery is 100Ah and your phone's battery is 3.6Ah (equivalent to 3600mAh), an entirely dead phone would draw less than 4% of the energy from your vehicle.

This isn't usually a huge concern for folks who buy new cars with good batteries. However, if your vehicle is older, you should avoid charging your phone over the USB connection.

Depending on the circumstances, that might be enough to kill your automobile battery. This is because car batteries have the same discharge issues as smartphone batteries, albeit on a much smaller scale. 

Your phone might quickly destroy your vehicle if your car battery is outdated. Charging a tablet or laptop is more likely to empty your vehicle battery fast since they have bigger-capacity batteries and consume a higher proportion of your car battery's stored charge.

Buy a Car Charger That Solves Your Problems 

The best iPhone car chargers and Android phone chargers feature protections that can switch off charging when your device is completely charged, so you don't waste your car's battery power. To prevent your car's battery from being drained once your gadgets are completely charged, make sure the charger contains these protection features.

The Qi Wireless Charger is an excellent way to keep your phone charged while on the go, and the built-in car cell phone holder is an added bonus. The charger is very easy to use, and the phone holder is very secure, making it a great hands-free option for safe driving. The Qi Wireless Charger is also case-friendly, so you don't have to worry about removing your phone case before charging. 

Overall, this is an excellent product if you consider safety and ease of use. I would highly recommend it to anyone!
