Have you ever plugged your phone into your car charger and after driving for about thirty minutes, look at your phone only to realize that it has only gone up by 2% or sometimes even gone down in percentage? If so, you’re not alone. In this blog post, we’ll discuss why your car charger may not be working as effectively as you would like and what you can do to fix it.
Let’s start with the basics of understanding the units of measure when it comes to charging your phone. The main ones to understand are watts, volts, amps, and milliamp hours. For the purposes of this post, we’ll only concern ourselves with milliamp hours, which is your battery capacity, and amps, which is the defining factor of how fast your phone will charge.
If your car charger only provides 1 amp, then it’s time to throw it out. Most phone batteries these days are too big to get a decent charge with only one amp of current running into your phone. Unfortunately, a lot of the cheaper car chargers only provide one amp. So, it’s essential to ensure that your car charger provides at least 1.5 amps of output.
The basic calculation to figure out how many amps of output your car charger needs to have in order to provide a sufficient charge is to convert your battery size into amps and then look for a car charger that provides no less than that amount of amp output. For example, if you have an iPhone 8 or 9 with a 3000 milliamp hour battery, you should have a charger with at least a 1.5 amp output.
In addition to the amp output, it’s also worth considering chargers with Qualcomm Quick Charge 3.0 technology. If your device is enabled with that technology, it’ll charge super fast – up to 80% in about 35 minutes.
It’s worth noting that your car’s USB ports may not provide sufficient charging for your phone. Most modern phones require at least 1.5 amps to get a decent charge, but many car USB ports aren’t designed for charging phones and only output 0.5 amps. Unfortunately, there isn’t a solution to fixing this other than buying a 12-volt car charger.
In conclusion, it’s essential to ensure that your car charger provides at least 1.5 amps of output and consider chargers with Qualcomm Quick Charge 3.0 technology. Don’t rely on your car’s USB ports to charge your phone, as they may not provide sufficient charging. Invest in a 12-volt car charger to ensure your phone charges quickly and effectively while on the go.
