12-24V DC car power inverter for Asus laptops

This iTekiro inverter plugs into a vehicle cigarette-lighter socket and delivers 19V output at up to 90W. It replaces Asus 65W and 90W AC adapters so you can run and charge compatible notebooks while driving. The 4.5mm tip with centre pin matches the listed Asus models.

90W maximum output limits use to lower-power Asus

The unit supplies 19V at 3.42A to 4.74A and is explicitly not a substitute for 120W or 150W chargers. Input range is 12V to 24V DC, so it works in most cars and light trucks. Built-in short-circuit and over-temperature protection shut the inverter down if a fault occurs.

Upgrades from carrying a separate AC adapter

Instead of running a household inverter from the lighter socket, this single device steps 12-24V DC directly to the laptop’s required voltage. The jump is worth it when you need a compact, dedicated charger for supported Asus ultraportables and want to avoid the bulk and efficiency loss of a two-step AC solution.
