How to charge a phone from a Kia EV4 USB charger
The EV4 manual distinguishes a USB charging terminal from a connection used to play media. Start by choosing the charging port and cable appropriate to your device rather than assuming every USB socket has the same role.
Checked against the MY2027 English owner manual for this model on 27 October 2026. Equipment and software can differ; use the instructions and controls fitted to your own vehicle.
Connect a compatible device with its suitable USB charging cable and check charging on the device itself. Fast charging requires a device with fast-charge support and compatible charging requirements.
Before you start
Park while connecting and arranging the cable. Check the device instructions if it requires a special adapter or charging method; Kia notes that some devices may not match the car charger.
Follow these steps
Tick steps as you go. Your progress stays in this tab.
Check the result
Charging speed can vary with the device and its current charging state. A phone without fast-charge support charges at a regular rate; the manual also notes fast charging may not work when some devices are switched off.
Common questions
Can I use the charging terminal to play music?+
The manual says not to use that charging terminal to operate audio or play infotainment media.

No. Device support, charging state and compatibility affect the result.
