90W, 125W or 150W? Car charger power, explained plainly
The big number on a car charger is the total across all ports. What your phone actually gets depends on the port, the cable and the protocol both ends agree on.
PD and QC in one line each
USB Power Delivery (PD) is the USB-C standard iPhones, Galaxies, iPads and laptops use. Quick Charge (QC) is the USB-A fast-charge standard older Android phones prefer.
How our chargers split power
90W: 45W USB-C + 45W USB-A. 125W: 65W USB-C + 60W USB-A. 150W: 65W + 65W over two USB-C ports, plus 20W USB-A.
What a phone really draws
Current iPhones peak around 27–40W, Galaxy Ultras around 45W. Anything above that is headroom — for a tablet, a laptop, or a second phone at full speed.
Why 12V vs 24V matters
Peak USB-A output on the 125W model is reached in 20V-capable systems such as trucks. In a typical 12V car, USB-C still delivers its full 65W.
Don't forget the cable
A 60W or higher USB-C cable is needed to pass 45–65W. Our 125W and 90W bundles include one.
Quick answers
With the engine off, most cars cut the socket. In cars that keep it live, unplug the charger when parked for days.
On our 125W and 90W models, the two ports share the chip — plugging both in lowers each port to a shared fast rate. The 150W model runs both USB-C ports at 65W together.
