Key benefits Fast charging for QC3.0compatible devices: USB1 supports the Quick Charge 3.0 voltage profile to reduce charging time for smartphones and tablets. combined output: total power up to 180W lets you charge more powerhungry accessories and multiple devices without overloading a single port. Wide vehicle compatibility: accepts 12–24V input, so it works in cars, trucks and other 12V–24V systems. Simple, reliable power for everyday use: one port optimized for fast charge protocols, a second port for steady current 5V charging. How this product solves common problems Cuts down on wait time by delivering QC3.0 fast charge voltages on USB1 for compatible phones and devices. Eliminates the need for multiple adapters by providing two outputs with different roles: a QC3.0 fastcharge port and a current 5V port. Adapts to different vehicle power systems (12–24V) so you can use the same charger in passenger cars, trucks or boats. Main specifications USB1 (QC3.0): DC 3.6V–6.5V / 3A; 6.5V–9V / 2A; 9V–12V / 1.5A (QC3.0) USB2: 5V / 3.6A (MAX) Total power: 180W Input voltage: 12–24V Performance and compatibility USB1 follows the QC3.0 voltage/current steps to maximize charging speed for compatible smartphones and tablets. USB2 provides a stable 5V current output suitable for power banks, Bluetooth speakers, dash cams and other accessories that need higher current. Designed for use with standard 12–24V vehicle power sources; ideal for drivers, professional vehicle operators and recreational vehicle users. Practical use scenarios Long road trip: simultaneously fastcharge a QC3.0 phone on USB1 and keep a tablet or power bank topped up on USB2 while driving. Rideshare or delivery driver: quickly recharge a smartphone between fares and maintain power for navigation and dash cam equipment. Boat or truck: compatible with 12–24V systems to provide steady charging for multiple devices during extended use away from home. What to expect in everyday use Fast, protocoldriven charging from USB1 for devices that support QC3.0. Reliable, current 5V charging from USB2 for accessories that need steady current. Works across 12–24V vehicle power supplies for broad compatibility. Exact technical values are listed above to ensure correct matching with your devices and vehicle power system.
