amguog 170W 20V 8.5A Slim Tip Laptop Charger for Lenovo

This is a 170W 20V 8.5A slim-tip replacement AC adapter from amguog made to power Lenovo laptops that require the yellow square slim connector (not USB-C).

If your Lenovo laptop originally shipped with a 170W slim-tip brick and you need a reliable replacement, this amguog adapter is built to match the same voltage and amperage specifications as many OEM models. It’s designed for models across the LOQ, Legion Slim, ThinkPad, Yoga Pro and IdeaPad families that specify a 20V 8.5A input and a yellow square slim tip. The unit includes smart protection features to help defend against common electrical faults and is a compact option for travel, home, or office use.

How do I know this charger fits my Lenovo model?

Confirm compatibility by checking your original adapter’s output label and the shape of the connector. This amguog charger provides 20V at 8.5A and uses the yellow square slim tip, so it only fits laptops that require that exact configuration.

• Check the adapter label for 20V 8.5A (170W) output.
• Ensure your laptop uses the yellow square slim tip connector, not USB-C or round tips.
• Match any listed replacement part numbers (e.g., ADL170NLC3A, 45N0370).
