SKU CH-VZMR-7RNEE

Replacement AC adapter supplying 20V 3.25A 65W or 20V 2.25A 45W with round tip for Lenovo IdeaPad and Yoga models, 110-240V input and DOE Level VI efficiency

  • Delivers 65W or 45W output for compatible Lenovo laptops
  • Worldwide 110-240V input suits travel across regions
  • Round tip connector fits listed IdeaPad, Yoga and Flex models
  • DOE Level VI rated for energy-efficient operation
  • Built-in protections guard against short circuit, overvoltage, overcurrent and overheating

Compatible Lenovo Models

This AC adapter fits a wide range of Lenovo IdeaPad and Yoga laptops including the 330, 330s, 510, 530s, S130, S530 and Flex 6-14 series. It also supports Yoga 710 models such as the 710-11, 710-14 and 710-15. Buyers with laptops outside these listed families should verify the connector and voltage before purchase.

Output Voltage and Wattage

The adapter delivers two fixed output profiles: 20V at 3.25A for 65W maximum or 20V at 2.25A for 45W maximum. Your laptop will draw the appropriate profile automatically. If your original charger specifies a different voltage or a higher wattage, this unit will not be suitable.

Round Tip Connection and Safety

A standard round tip plugs directly into the laptop power port without tools or adapters. The unit includes short-circuit, overvoltage, overcurrent and thermal protection and meets DOE Level VI efficiency requirements. Ensure the tip seats fully; a loose fit can cause intermittent charging.

Questions about this item

What does the 65 W output actually deliver to my laptop?

It supplies up to 20 V at 3.25 A, giving a maximum of 65 W for models that draw the full rating.

How does the round-tip connector limit which Lenovo models can use it?

The round tip fits the listed IdeaPad and Yoga models that use a 20 V barrel jack; other tip sizes will not connect.

What clearance does the adapter need behind the laptop for the plug and cord?

The barrel plug inserts directly into the laptop's round charging port; allow space for the cord to run straight out without sharp bends.
