90W 4-Port Car Charger

The KYOHAYA charger delivers up to 90 watts from a single cigarette-lighter socket using two USB-C and two USB-A ports. It is built for drivers who need to power phones, tablets and other USB devices simultaneously while on the road.

iActivePower Safety System

An embedded E-Marker chipset and dynamic temperature sensor monitor heat in real time and adjust current output to each port. The integrated superconductor material reduces resistance, keeping the adapter cool and stable during normal multi-device charging.

Sustained Load Behaviour

Under continuous high-demand charging the power tuner chip actively regulates output to prevent overheating and protect connected device batteries. Intelligent power distribution maintains balanced delivery across all four ports without thermal throttling.

Questions about this item

How do I install the 90W 4-port charger and what step do people get wrong?

Plug the adapter firmly into the 12 V cigarette lighter socket until it seats fully; the common mistake is leaving it loose, which breaks contact and stops the 90 W output.

What maintenance or replacement will the KYOHAYA 90W charger need later?

No scheduled maintenance is required; keep the ports free of dust and replace the unit only if the Dynamic Temperature Sensor triggers permanent shutdown.

What limit appears first during sustained use of the 90W 4-port charger?

The Dynamic Temperature Sensor monitors heat in real time and the Power Tuner Chip reduces output once the internal temperature threshold is reached.
