Replacement USB-C power adapter

This 65 W USB-C AC adapter replaces the original charger for a wide range of Chromebooks and business notebooks. It suits students, mobile professionals and IT teams who need a single spare or travel unit that works across multiple brands and models.

USB Power Delivery voltage steps

The adapter accepts 100-240 V AC input at 1.6 A and delivers four fixed output profiles: 5 V at 3 A, 9 V at 3 A, 15 V at 3 A and 20 V at 3.25 A. Devices that require voltages or current levels outside these steps will not charge from this unit.

Maximum 65 W output ceiling

The charger tops out at 65 W, so any laptop that draws more power under load — such as larger workstation-class machines or gaming models — will either charge slowly or not at all while running. Buyers needing higher sustained wattage should look for a more powerful adapter.

Questions about this item

Should I choose the 65W or 45W version for my Latitude 5420?

This adapter delivers up to 65W and automatically negotiates 5V-3A, 9V-3A, 15V-3A or 20V-3.25A, so it covers both 65W and 45W requirements for the Latitude 5420.

What does the 65W rating actually deliver to my ThinkPad Yoga 3100?

At 20V-3.25A the charger supplies the full 65W your Yoga 3100 can accept, while lower profiles (5V, 9V, 15V at 3A) handle standby or lighter loads without overheating.

Does the USB-C connector limit charging speed compared with a barrel jack?

The USB-C output provides the same 20V-3.25A (65W) profile as the original barrel-jack adapter, so there is no practical cap for the listed ThinkPad, Latitude and Chromebook models.
