  • TypeAC Adapters
  • Delivers 65 W for fast charging

65W USB-C Style Adapter for IdeaPad

This 65W AC adapter delivers 20V at 2.25A or 3.25A through a 4.0×1.7 mm connector. It accepts 100-240V input at 50-60Hz and is rated for at least 10,000 hours of service life. The unit uses reinforced cables and a precision metal plug to maintain stable power delivery.

Suits IdeaPad owners needing a 65W replacement

Buyers with Lenovo IdeaPad 1, 3, 5, Flex, V-series, Chromebook N22 or N23 models using the 4.0×1.7 mm tip can use this charger. It also covers 45W requirements for compatible systems. Users whose laptops require a different connector size, a higher wattage, or a proprietary rectangular plug should look at other options.

4.0×1.7 mm connector decides fit

The barrel diameter and pin width are the only specifications that determine physical compatibility with the laptop. If the original charger uses this exact 4.0×1.7 mm connector, this adapter will mate correctly. Any other tip dimensions mean the part will not connect.

Questions about this item

Should I pick the 20 V 2.25 A or the 20 V 3.25 A output for my IdeaPad?

The adapter delivers both 20 V 2.25 A and 20 V 3.25 A automatically; your laptop draws the current it needs up to 65 W and it also covers 45 W models.

What does the 65 W rating mean when the charger is plugged into my laptop?

It can supply up to 65 W at 20 V, with the 3.25 A peak available for higher-load models while still running cooler on 45 W systems.

Does the 4.0 × 1.7 mm barrel connector limit charging speed on any listed IdeaPad?

The 4.0 mm by 1.7 mm tip matches every model in the compatibility list, so the connector does not restrict the 65 W output.
