Charging Limits and Card Capacity

Two USB ports deliver power simultaneously: an orange QC3.0 port at 3.5-6.5 V 3 A, 6.5-9 V 2 A and 9-12 V 1.5 A, plus a blue 2.4 A port fixed at 5 V. TF or micro SD cards are accepted only in FAT format up to 32 G.

Adjustable Display and Power-Off

A 1.7 inch LCD with backlight shows track titles, caller ID and vehicle battery voltage at start-up. The screen rotates through 270 degrees on a gooseneck for comfortable viewing. Holding the next-track button for five seconds disables the FM transmitter while keeping the charging ports active.

Should I use the orange QC3.0 port or the blue 2.4 A port for my phone?

Use the orange QC3.0 port for compatible devices to get 3 A at 3.5-6.5 V, 2 A at 6.5-9 V or 1.5 A at 9-12 V; the blue port delivers 5 V at 2.4 A for standard charging.

What does the 1.7 inch display actually show while I am driving?

The LCD backlight shows the current song name, incoming phone number and the vehicle battery voltage at start-up, and the 270-degree gooseneck lets you angle it for easy reading.

How does the 12-24 V input affect charging speed on the two USB ports?

The adapter accepts 12-24 V from the vehicle socket; the QC3.0 port negotiates 3.5-12 V output up to 3 A while the 2.4 A port provides a fixed 5 V at 2.4 A regardless of input voltage.
