Compatible Lenovo Ideapad models

This 90W AC adapter replaces the original charger for Lenovo Ideapad 700 and 720S 15-inch laptops. It matches the 20V 4.5A output required by the listed sub-models. The package includes a 6 ft 2-prong AC power cord for flexible placement. Worldwide 100-240V input lets you use it abroad without a voltage converter.

Who this suits and who it does not

It suits owners of the specific Ideapad 700 and 720S 15-inch variants named in the compatibility list who need a direct replacement. It is not for laptops that require a higher output than 90W or a different voltage and current combination. It is also not for models that use a USB-C or proprietary connector not covered by this barrel-plug design.

Output specification that decides fit

The adapter delivers 20V at 4.5A for a total of 90W. Confirm your laptop's label shows exactly 20V and 4.5A or 90W maximum before purchasing. The tip polarity and dimensions must also match the original barrel connector used on the supported Ideapad models.

Questions about this item

Will this 90 W 20 V 4.5 A adapter run my Ideapad 700 or 720S-15IKB alongside the original charger I keep as a spare?

Yes — it matches the 20 V 4.5 A output your Ideapad 700 and 720S-15IKB models expect, so either unit will power the laptop identically.

How can I confirm the adapter is delivering the rated 20 V 4.5 A after I plug it in?

The laptop’s battery indicator will show charging at full speed and the adapter’s LED stays solid; no voltage drop or warning appears when the system draws the full 90 W.

Does the package include the 6 ft 2-prong AC cord or must I buy it separately?

The 6 ft 2-prong AC power cord is included in the box; nothing else is required to start charging.
