Charging a phone in a vehicle is a very simple exercise, especially when you have the necessary tools to perform the task. Some of the tools include a car charger, USB cable, or a cigarette lighter. Once you have any of these tools, you’re good to go.

Meanwhile, the procedure below is a step-by-step guide on how to charge your phone when the car is off.

Step 1: Get a car charger/USB cable/cigarette lighter

Firstly, get an aftermarket recommended car phone charger, a USB cable, or a cigarette lighter if you don’t already have any. The three devices can be used to charge your phone. So, you may have to stick to one of them.

However, using car phone charger is the best way to charge phone in a car because it is designed for that purpose compared to the other two devices. However, they can still work if you choose to use them as alternatives.

Step 2: Insert the charger into the designated port

Once you have the charger, kindly locate the car phone charger port beneath the dashboard at the center point between the driver’s seat and the passenger’s seat in front. Then, insert the charger into the port carefully.

Also, if you have a USB cable, ensure to locate the USB port around the same spot between the driver’s seat and the passenger’s seat below the dashboard. You can as well find a cigarette lighter around the same area. However, kindly check your owner’s manual to ascertain the exact location.

Step 3: Plug the charger tip into the phone charging port

Now, pick the part of the charger with the phone charging cable tip and insert it into your phone. Ensure that you’re using the appropriate charger for your phone, especially for iPhone users.

Meanwhile, if you’re using a USB cord, simply insert the other end that is compatible with your phone into the charging port. Again, ensure that the cable matches the charging port of the phone you intend to charge.

Step 4: Verify the phone’s battery charging icon.

Lastly, verify if the phone is charging appropriately by checking for the battery-charging icon on the phone. Some phones have their battery icon on the top right corner of the phone’s screen. Also, the charging icon usually appears like a small thunderbolt near the battery.

Once you verify and spot the charging icon, you’re good to go. Your phone’s battery should be full in a few hours. However, do not leave the phone charging for too long. Also, never make this a daily habit, as you may be endangering your car’s battery life in the long run.
