iSmart: iSmart technology automatically detects and delivers the optimal charge; making it the fastest, most effective way to power any connected device. With two 2.4A iSmart ports, fast charging has never been easier.
CONSTANT CHARGE: The battery input of 12-24V is standard across all cars; however there are times when it can exceed this standard. When you hit the ignition switch or when the car accelerates, the input can be anywhere from 8V to as high as 30V. No matter the voltage, the USB charger will automatically adjust to protect your device and charge at a steady rate.
GREAT POWER, GREAT RESPONSIBILITY: The car charger comes with a number of built-in protection methods to keep your device safe. The built-in over & under voltage, over-current, and over-temperature protections ensure your mobile phone and other device's safety needs are guaranteed.
