Slim 170W Charger Fit for Lenovo Legion Slim 5 - Reliable Replacement

Our review examines the Slim 170W Charger fit for a range of Lenovo laptops and finds it most suitable for users who need a dependable, high-power replacement charger without paying OEM prices. The main takeaway is simple: this adapter delivers the expected power delivery and broad compatibility, including a 20V 8.5A output and the slim square yellow tip used by many Lenovo models, making it a practical substitute for a lost or damaged original. For anyone needing a robust 170W replacement that matches original charging behavior, this is a solid option.

Key Features

• High output: 170W maximum (20V 8.5A) provides full power for demanding laptops so users can run heavy workloads while charging.
• Wide compatibility: Works with many Lenovo models and recognizes lower 135W (20V 6.75A) profiles when needed to maintain safe charging on different machines.
• Trusted connector: The slim square yellow tip offers a direct fit for laptops that require Lenovo's proprietary connector for secure power delivery.
• Safety protections: Built-in safeguards and a cooling system reduce risk from overcharging, short circuits, and overheating for long-term device protection.
• Universal input: 100-240V 50/60Hz input makes the adapter usable worldwide with standard voltage, handy for travel or varied power sources.
• Quality control: The product line undergoes rigorous testing and UL safety checks to provide consistent and reliable charging performance.

Who It's For

This adapter is aimed at Lenovo laptop owners who need a like-for-like replacement for a missing or failing power adapter, particularly users of Legion Slim, ThinkPad P1 and P15 series, Yoga Pro, IdeaPad Pro, and other models listed by Lenovo parts compatibility. It is especially useful for power users who run graphics, video, or CPU intensive tasks and require the full 170W output to avoid throttling while plugged in.

It is not the best choice for users whose laptops use a different connector style or much lower wattage adapters, or for those who want a compact USB-C only solution. Buyers who require vendor-authorized service or branding may prefer obtaining an OEM adapter through official support channels.
