Plugging your phone into your car to charge it up when your engine isn’t running can discharge your car battery. Your car battery is practically killed as you charge your phone in a car without a battery that carries deep cycle capabilities. The lifespan of your car battery would be shortened even after it has been successfully “resuscitated”.
Most car manufacturers allow power to flow to the cigarette port only after we turn on the ignition. This important feature conserves your car battery as it enables control of the electrical demands required.
There are some car models that enable electrical power to be pulled from the cigarette port when the ignition is turned off. Car owners should be mindful of this feature so that they would not end up returning to a car with a drained car battery.
Understanding Our Smartphones Battery
Most of today’s smartphone batteries adopt lithium polymer technology. Their capacity is measured in milliamp hours (mAh). For instance, iPhone 6 has a capacity of 1,810mAh.
Smartphone batteries power up in three phases:
The speed of charging relies on the type of charger used. This is applicable only in the charging Phase 2 (Constant Current Mode). To break things down, a cable is just like a water pipe with different numbers representing the size of the opening. This pipe helps electrons flow from one part of the circuit (power source- cigarette port in your car) to another (battery in your phone). Let us explore 2 popular smartphone brands and their charging standards.
It is useful to understand your needs and the types of charger available in the market in order to pick the most suitable charger for your car. Our Voltage Monitoring Car Charger has a maximum output of 3.1Amps and 5 Volts. It can support most of the smart devices in the market, including tablets, while keeping you well-informed of your charging. You should not use a charger that has a lower spec than your smart devices.
Effects Of Charging Your Phone In Your Car
Charging your phone via your car cigarette port is an energy transfer from your car’s battery to your phone battery. Technically, if you have a 100Ah car battery, and your phone’s battery is 1.8Ah (which is equal to 1800mAh), a completely dead handset battery would pull less than 2% of the charge out of your car battery. Depending on the circumstances, this 2% might be enough to drain your car battery. Since car batteries suffer from discharge problems that are similar to smartphone batteries, a 20% upgrade on your battery size is recommended. (read more to find out why)
What Can I Do?
It is indeed a hassle to restore a car with a dead battery. You might even spend more to get your car towed away for a check-up when it is only a battery problem. This happens frequently among beginner drivers. To save you from the panic-attack and inconvenience to get your car’s battery replaced, you can practise the following in order to have a long-lasting battery and maximise your dollar spend:
If you have a car with start stop function, in-car camera(s), and you charge electronic devices in the car, AGM battery is cut out for you as it is built to withstand discharging and recharging process. You will get to enjoy less downtime and save more money in the long run.
