The Lenovo 300W Slim AC adapter (model 5A10W86289) delivers up to 300 watts of power in a compact, low-profile housing designed for compatible Lenovo laptops and mobile workstations. Its slim form factor reduces weight and bulk compared with traditional brick-style adapters while providing stable power for charging internal batteries and running power-hungry applications. This adapter is intended as a replacement or spare to maintain reliable operation when the original adapter is unavailable.

Advantages

The slim design combines portability with high output, making it easier to carry between work locations. Built-in protections help safeguard connected devices from overcurrent, overvoltage and short circuits. The adapter provides consistent power delivery at full rated output so laptops can operate at peak performance without battery drain. Connector and cable length are designed to provide convenient placement during use.

Suitable for

• Charging and powering compatible Lenovo high-performance laptops and mobile workstations
• Use as a replacement or spare adapter for travel and office use
• Situations requiring a compact adapter that still delivers 300W output
• Environments where a lower-profile power supply improves portability and storage

How to use

Connect the detachable AC mains cable to the adapter and plug the mains cable into a properly grounded outlet. Insert the adapter's DC connector into the laptop's power input until it seats firmly.
