How to choose a car charger by negotiated power rather than the largest printed wattage
USB Power Delivery allows devices and chargers to negotiate voltage and current rather than sending maximum power continuously.
USB-IF states that USB PD supports power levels up to 240 watts under the current extended power range specification.
Match the charging protocol
A charger’s headline wattage may be shared across ports, so per-port output under simultaneous use matters.
Read shared-output tables
Higher-power modes require suitable USB-C cables, including electronically marked cables at certain current and power levels.
Verify the vehicle outlet and cable
The vehicle accessory outlet and its fuse remain the upstream limit, regardless of the charger label.
