  • Works from 12V-24V cigarette lighter sockets in cars and trucks
  • Single adapter replaces multiple proprietary power bricks

What this product is

The ALSEYE 90W car charger adapter supplies 20V at 4.5A through a 7.9*5.5mm round connector. It draws power from a 12V-24V cigarette lighter socket and is compatible with a wide range of Lenovo laptops and tablets including ThinkPad, IdeaPad, Edge and 3000 series models.

Who this suits and who should look elsewhere

Mobile professionals who need to charge supported Lenovo devices from a standard vehicle power outlet will find this adapter convenient. It is not suitable for vehicles with a 36V cigarette lighter system, nor for laptops that require a different connector size, voltage or current rating.

Capacity and headroom

The 90W output comfortably handles charging and simultaneous use for most listed Lenovo models drawing up to 4.5A at 20V. It also supports lower-current 20V 3.25A and 2.25A requirements. Headroom runs out if the vehicle supplies only 36V or if the connected device demands more than 90W.

Questions about this item

My laptop uses a 7.9*5.5 mm barrel plug — will this charger fit it?
