Like many people who use their car regularly, I like to charge my phone when I'm driving so that it isn't flat with I get to wherever I'm going. I know that some computers have a fast charge port specifically designed to charge such devices.
If I am only going a short distance and have forgotten to charge my phone overnight, or it has been subject to heavy usage or whatever else the case may be, I would like to be able to maximise the amount of charge my devices will get.
How can I charge my phone using an in-car charger as fast as possible?
In other words:
- How do the alternator, transformer and battery each affect the rate of charge respectively (if at all)?
- Do you have any tips for fast in-car charging (or how to avoid it being unnecessarily slow)?
- Is there any way to charge a phone or tablet faster through the car than a standard USB port adapter like this one?
