A device designed to replenish the battery of Android-based mobile phones and tablets quickly while in a vehicle. These chargers plug into the car’s power outlet (typically a cigarette lighter or 12V auxiliary power socket) and utilize various charging protocols to deliver power at a faster rate than standard chargers. An example is a charger advertising “Quick Charge” compatibility, capable of significantly reducing the time required to charge a compatible Android phone.
The significance of rapid in-vehicle replenishment lies in its ability to maintain device functionality during travel. This proves particularly useful for navigation, communication, and entertainment needs. Historically, mobile phone charging in cars was limited by the slow charging speeds of early USB standards. However, advancements in power delivery technology, such as Qualcomm’s Quick Charge and USB Power Delivery (USB-PD), have enabled much faster and more efficient charging while on the go.
