How to choose an Original Lenovo laptop adapter
Reviewed 10 October 2026. Match the adapter to the exact laptop model, required output voltage, power rating and connector. For USB-C charging, check the supported charging standard, power profiles and cable. A matching brand or plug alone is insufficient.
Lenovo connector and power checks
A Lenovo rectangular slim-tip connector is different from USB-C, even when a listing calls it a “USB pin”. Check the actual plug shape and supported adapter specification. Lenovo models can also use round-tip connectors; one adapter type does not cover every ThinkPad or IdeaPad.

| Published adapter | Price (LKR) |
|---|---|

| Lenovo (China) Original 135W 20V 6.75A Laptop Adapter | 16,000 |
What should you read on the old adapter label?
Record output voltage, current and rated power. For a DC barrel adapter, voltage multiplied by current gives the approximate rated watts. Match voltage, connector dimensions and polarity, then verify the current and power requirements for the exact laptop.
Can I use a higher-wattage adapter?
Only when the laptop manufacturer supports that specification. Higher rated power alone does not prove compatibility. An insufficient power rating may cause slow charging, no charging during use or restricted performance. Confirm the approved adapter rather than relying on a universal wattage rule.
Will any USB-C adapter charge my laptop?
No. The laptop must support charging through that port, and the adapter and cable must support the required power delivery arrangement. A phone charger or USB-C data cable may not meet those requirements.
What if the laptop still does not charge?
The fault may involve the adapter, charging port, battery or another component. Describe whether charging is intermittent and whether the laptop recognises the adapter. Ask for assessment when the cause is uncertain.
Before ordering
Send the full laptop model and a clear photo of the old adapter label and connector to Richcom. Confirm the output, connector requirements, availability and warranty before purchase.
