  • 90W output charges four devices at once

Rombica 4-Port 90W Car Charger

The Rombica 4-Port 90W Car Charger plugs into a cigarette-lighter socket and delivers up to 90 W across four ports. It ships with an MFi-certified USB-C braided cable that includes an E-Marker chipset and a 56 kΩ pull-up resistor for safe voltage negotiation. Drivers who need to charge multiple phones, tablets or accessories on the road will find the combination of USB-C and USB-A outputs convenient.

Installation and common issues

Insert the adapter firmly until it clicks; a loose fit can cause intermittent power. The integrated dynamic temperature sensor and power tuner chip automatically adjust output to protect connected devices, so overheating is rare. If a port stops responding, unplug all cables, wait a few seconds, then reconnect — this resets the intelligent power management chip. The braided cable resists tangling but should not be bent sharply at the connector.

Sustained-load behaviour

Under continuous multi-device charging the temperature sensor monitors heat in real time and the power tuner chip scales current to keep each device within safe limits. The superconductor material reduces resistance, helping maintain efficiency during long trips. Output remains stable across all four ports without the sharp drops seen in simpler adapters. The system prioritises battery health over raw speed when thermal headroom is limited.

Questions about this item

How can I verify the 90W charger is delivering power to all four ports after plugging it into the cigarette lighter?

The built-in Dynamic Temperature Sensor and Power Tuner Chip actively monitor temperature and adjust output for each connected device; normal operation means your iPhone 17, Galaxy S25, or Pixel charges without overheating warnings.

What comes in the box and which cables must I purchase separately?

The package includes the 4-port 90W car charger adapter and one MFi certified USB-C braided cable with dual E-Marker chips; additional USB-C or USB-A cables for the other three ports are not included.

Which version should I choose between the 4-port, 3-port, 2-port, and 1-port options shown?

Select the 4-port 90W model if you need to charge four devices such as an iPhone 17 Pro, iPhone 16, Galaxy S26, and Pixel simultaneously; choose fewer ports only if you regularly charge fewer devices.
