SKU CH-7WN5-7E5ZW MPN Q46EU-200002250

45W AC adapter compatible with numerous Lenovo IdeaPad and Yoga models

  • TypePower Adapter
  • 45 W output powers compatible Lenovo laptops efficiently
  • 100-240 V input enables worldwide use without a voltage converter
  • Ready2Tech branding confirms Lenovo-approved replacement quality
  • Replaces multiple Lenovo part numbers for broad model coverage
  • Black compact design fits easily in a travel bag

45W Lenovo AC Adapter

This 45-watt Lenovo power adapter replaces the original charger for a wide range of IdeaPad and Yoga laptops. It supports models from the 100, 110, 120, 300, 500 and 710 series as well as selected Flex devices. Buyers who need a charger for the 11.6-inch IdeaPad 100S-11IBY cannot use this unit.

Simple plug-in replacement

Installation only requires connecting the barrel tip to the laptop and the mains lead to a wall socket. The 100-240V input handles international voltage automatically. The most common issue is ordering this adapter for the 100S-11IBY, which needs a 3.5 mm tip instead of the standard connector supplied here.

Steady 45W output under load

The adapter maintains its rated 45-watt delivery during continuous charging sessions without throttling. Heat stays within normal limits for a compact brick of this class. It is not designed for laptops that draw more than 45 watts, so higher-power models will charge slowly or not at all.

  • 100-240 V input enables worldwide use without a voltage converter

Questions about this item

How do I confirm the 45W adapter is charging my Yoga 710-11ISK correctly after connecting it?

The laptop's charging indicator LED should illuminate and the battery icon in the operating system must show a charging state with the correct wattage detected.

What comes in the box with the Q46EU-200002250 and is a separate power cord required?

The package includes the black 45W AC adapter unit with its attached output cable; a detachable AC mains lead for the 100-240V input must be purchased separately if not already owned.

Which Lenovo models does this 45W Ready2Tech adapter support and which 11.6" model is excluded?

It supports listed Ideapad 100, 110, 120, 300, 500, 710S, Yoga 710 and Flex series models, but is not compatible with the 11.6" Ideapad 100S-11IBY which requires a 3.5 mm connector.
