170W 20V 8.5A Square Yellow Tip Charger

This new Astro Gaming 2-in-1 accessory is a 170W AC laptop charger delivering 20V at 8.5A through a square yellow tip connector. It accepts a universal 100-240V input at 50-60Hz and also supports 135W 20V 6.75A requirements. The unit serves as a direct replacement power supply for a wide range of Lenovo ThinkPad models.

Fits ThinkPad P and T series workflows

The adapter matches part numbers including ADL170NLC2A, ADL170NLC3A, ADL135NDC3A, PA-1171-71 and PA-1131-72, covering models such as the P50, P51, P52, P53, P70, P71, P73, T440, T450, T480, T540P, T550 and T580. Built-in multi safeguards and a cooling system protect against overcharging, short circuiting, overheating and spark risks while intelligently monitoring temperature. This frees the user from carrying a separate proprietary brick when moving between compatible workstations.

For ThinkPad owners needing 170W

Buyers with a listed ThinkPad requiring a square yellow tip connector at 170W or 135W will find a compatible, new replacement here. Users whose laptops demand a different connector shape, a higher wattage rating, or a USB-C power delivery profile should look at other options, as this unit is limited to the specified barrel interface and output range.

Questions about this item

Will the 170W output handle continuous heavy workloads without throttling?

The adapter delivers up to 170W at 20V 8.5A and includes built-in safeguards with a cooling system that monitors temperature to protect against overheating during sustained use.

How much heat or fan noise does the power brick produce when running all day?

A multi-protection cooling system is built in to manage heat intelligently; no fan is mentioned, so operation relies on passive thermal management and temperature monitoring.

Which cable or connector must I already have to use this charger with my ThinkPad?

The unit terminates in a square yellow tip connector that matches the listed ThinkPad models; you only need a working AC mains lead for the 100-240V input.
