Dual USB Car Charger with LCD Voltage Display

This PALUMMA charger plugs into a 12 V cigarette-lighter socket and delivers up to 24 W total output. Two USB ports each provide 5 V at 2.4 A, automatically adapting to the connected device. An integrated LCD shows the vehicle's operating voltage and the combined charging current in real time.

Replaces basic single-port chargers without

The dual-port design lets two devices charge simultaneously at full 2.4 A per port, removing the need to swap cables. The built-in voltage meter warns of low battery voltage with flashing green LEDs, so drivers can spot electrical issues before they cause a breakdown. The upgrade is worthwhile when you regularly charge a phone and a tablet or need constant visibility of the vehicle's electrical system.

All-metal housing manages heat during extended use

The zinc-alloy body acts as a heatsink, keeping temperatures stable when both ports run at 4.8 A combined for long journeys. Protection circuits guard against short circuit, over-current, over-heating and over-charging, while the charger stops supplying power once a battery reaches full capacity. Soft LED illumination makes the ports easy to find at night without distracting the driver.
