Six-port 300 W charger
This 300 W car adapter offers four USB-C ports and two USB-A ports for drivers who need to charge laptops, phones and tablets at the same time. The USB-C2 port delivers up to 140 W using PD 3.1 while the other USB-C ports supply 30 W, 35 W and 30 W. Each USB-A port provides 60 W QC 3.0 for legacy devices.
Replaces single-port adapters
It replaces older car chargers that only support one high-power device, letting a MacBook Pro 16 reach 80 % in 30 minutes while phones charge at 27 W or 45 W. The jump is worth it when you regularly carry a laptop plus multiple phones or a tablet on long trips. Buyers who only ever charge one phone will not use the extra ports.
Sustained multi-device output
Smart IC management allocates power across all six ports without overheating during continuous use. The charger maintains PD 3.1, PPS, QC 3.0, SCP and AFC protocols simultaneously so each device receives its optimal rate for the whole journey.

Questions about this item
Which vehicle power socket does the 300 W charger plug into?
It connects to a standard vehicle DC accessory socket and draws power through a single outlet to supply all six ports simultaneously.
What is the most common mistake when installing the charger for the first time?
Users often forget to fully seat the plug until the LED ring lights, which confirms the internal smart IC has started negotiating PD 3.1 or QC 3.0 with each device.
When should the unit be replaced instead of just cleaning the contacts?
Replace it if any USB-C port stops delivering its rated output — such as the 140 W PD 3.1 port dropping below 100 W or the 45 W PPS port failing to trigger fast charge on a Galaxy S25 Ultra.
