What are the electrical and connector specifications?

The adapter accepts worldwide mains input and delivers regulated DC outputs suited to the targeted laptop models. Two typical DC output options are provided to match different internal power circuitry: lower-amperage modes for lighter systems and higher-amperage modes where more current is required.

• Input: 100–240V AC, 50–60Hz — compatible with international outlets.
• DC output options include 20V at 2.25A and 20V at 3.25A; rated for a maximum of 65W.
• Connector size: 4.0 × 1.7 mm barrel tip — verify your laptop’s jack matches this size.
• Also cross-compatible with certain 45W Lenovo parts when power draw is lower.

How durable and safe is this replacement adapter?

This adapter is constructed to withstand daily use with reinforced cabling and a precision metal plug at the interface to reduce heat buildup and maintain a steady connection. The manufacturer rates the unit for lengthy service life and has used thicker internal conductors to improve mechanical strength around the connector.

• Reinforced cable and bold conductor cores for improved wear resistance.
• High-precision metal triangular plug designed to minimize resistance and heat.
• Durability rating quoted at approximately 10,000 operational hours under normal use.
• Built-in regulation to help protect devices from routine voltage fluctuations.

How do I confirm this charger is right for my laptop?

Compare your original adapter’s output labels and connector shape with the specifications below, and check manufacturer part numbers on your device or existing charger. If your laptop lists a 20V DC input and uses a 4.0×1.7 mm barrel plug, this unit is likely a match; when in doubt, compare exact model suffixes or consult your device’s support documentation.

• Match the barrel plug size: 4.0×1.7 mm is required for physical fit.
• Verify voltage: laptop must accept 20V DC input.
• Confirm current/power: device should not require more than 65W continuous power.
• Check OEM part numbers listed on your original adapter for cross-reference.

Who is this for: The IKFJQCOA 65W adapter suits owners of Lenovo IdeaPad, Flex and S-series laptops or compatible Chromebooks who need a reliable, compact replacement charger that supports international power input and uses the common 4.0×1.7 mm barrel connector.
