Product Identity

The myVolts 20V 4.5A 90W USB-C AC Adapter delivers 90 watts of power through an 11mm x 5mm connector. It accepts a 100-240V input range for worldwide use and includes an extended 10-foot cord length for flexible placement.

Compatibility Fit

This adapter suits owners of listed Lenovo ThinkPad, IdeaPad, Yoga, Chromebook and Edge models that require a 20V 4.5A 90W supply with the 11mm x 5mm tip. It is not for buyers whose devices need a different voltage, amperage, wattage or connector size.

Questions about this item

What laptop connector must my device have to use this 11mm x 5mm tip?

Your laptop needs a barrel-style charging port that accepts an 11mm outer diameter and 5mm inner diameter plug.

Can I use this 90W adapter on a ThinkPad that originally shipped with a 65W 20V 3.25A charger?

Yes, the higher 90W capacity at the same 20V output is safe and will charge compatible ThinkPad models normally.

How do I confirm the adapter is delivering power once plugged in?

The laptop’s charging indicator should light up and the battery icon will show it is receiving 20V 4.5A input.
