1.It is specially made for power-hungry devices. Convert and increase your car cigarette lighter from 1 to 2 sockets as well as 2 USB ports; Multi Charging Adapter. 2.Automatic stops charging when there is danger of overcharging or lower/over voltage with build-in fuse. 3.Safely charge any USB powered devices, port for Apple Devices (also for Blackberry) and Samsung/HTC port for Non-Apple Mobile phones (like Samsung Galaxy S4, NOTE2 and HTC ONE) or other devices.(Use your existing USB charging cables) 4.Input DC 12V / 24V compatible without interference to Radio, Bluetooth or WiFi   Devices with smart-IC control: The device displays the max output 3.4A. It doesn't mean that output is 3.4A allways , which is based on the voltage and current that can be tolerated by the charged device to intelligently control the device On the basis of the most efficient charging.   Why can't cellphone charges reach 2.4A or higher? 1: the cell phone doesn't support any technology;
2: mobile phone doesn't support Qualcomm's technology
3: the charging current will be restricted by the quality of charging wire
4: the battery capacity is different, the output current will be different,   Mobile phone support other types of technology, the current mainstream technology has: Qualcomm's QC, MediaTek PEP, OPPO VOOC;standards are many, different standards are incompatible with each other.   High-current fast charge standard must choose high-quality USB data cable to meet the needs of current transmission, some of the max load line charge on the 1A or 2A also can't  support the maximum output current charger   QC2.0 is 9V/12V two-speed adjustment; QC3.0 upgrade to 3.6V-12V stepless adjustment, this advantage is based on the phone's load and heat automatically adjust the voltage to improve the charging efficiency. So the value of the voltage and current detection will be different because of different power, such as low power may be after the 2.4A, after the high power is 1A
