Vehicle power adapter for Lenovo IdeaPad 3

This iTekiro auto charger powers compatible Lenovo IdeaPad 3 models from a vehicle cigarette lighter socket. It accepts 12 to 24 volt DC input and delivers 20 volts at 2.25 amps for 45 watts of output power. The unit replaces the standard AC adapter when mains power is unavailable. A 90-degree DC plug reduces strain on the laptop power jack.

Input range and protection limits

The adapter operates from 12 to 24 volt DC sources found in cars, boats and RVs. Built-in protection guards against short circuits and over-temperature conditions. The output is regulated to 20 volts 2.25 amps regardless of input voltage within the supported range. An LED indicator shows when power is being supplied.

Output capacity and practical headroom

The 45 watt output matches the original Lenovo 20V 45W adapter rating and also replaces 65 watt genuine units. It will run the laptop and charge the battery simultaneously under normal workloads. Very high sustained loads that exceed 45 watts may cause the adapter to limit output or shut down until the load drops.
