Tripp Lite Dual-Port USB Car Charger For Tablets and Cell Phones With Qualcomm Quick Charge 3.0 Technology - Car Power Adapter - 30 Watt - 3 A - QC 3.0 - 2 Output Connectors (USB) - White - U280-C02-S-QC3U

This dual USB car charger with Qualcomm Quick Charge 3.0 technology lets you quickly and safely charge two USB-powered mobile devices at the same time. You and a passenger can connect your smartphones, tablets or MP3 players, to name just a few compatible devices, to ensure satisfactory battery charge when you reach your destination. The dual-port USB car charger is certified to UL 2089 standards for vehicle battery adapters rated 24V DC or less. One of the two charging ports is powered by advanced Quick Charge 3.0 technology. Instead of charging at a preset power level, this charger adjusts to one of three possible power levels to provide as much power as your QC-compliant device's battery can handle. Available outputs include 3.6 - 6.5V 3A, 6.5 - 9V 2A and 9 - 12V 1.5A.
The second USB port features auto-sensing technology that detects the connected device and automatically adjusts to the appropriate power level up to 5V 2.4A, perfect for fast-charging tablets and e-readers. It's compatible with Apple, Android, Windows and Amazon devices with USB-A charging ports.
The compact dual USB car charger adapter connects to any standard 12V DC vehicle power outlet, such as the one on your dashboard. Just plug it in, and connect your devices' USB cables for fast, convenient mobile charging. An easy-to-see LED indicates the charger is receiving power.
