170W Square Yellow Slim Tip Adapter

This 170-watt AC adapter uses a square yellow slim tip connector to power compatible Lenovo laptops. It delivers 20 volts at 8.5 amps and accepts a 100 to 240 volt input for worldwide use. The unit weighs 0.617 kilograms and includes a detachable power cord.

Sustained 170W delivery with lower-wattage fallback

The adapter maintains its full 170-watt output continuously under load rather than only in short bursts. It also operates safely with devices rated for 135, 90 or 65 watts by negotiating the appropriate power level. Input frequency ranges from 50 to 60 hertz.

Simple plug-in install.

Installation requires only connecting the slim tip to the laptop and the cord to a mains socket. The most frequent problem is attempting to use the adapter on a system that needs more than 170 watts or a different connector shape. Verify the square yellow tip matches the device before purchase.

Questions about this item

Does the 170 W adapter stay cool and quiet when it runs all day?

The brick is passively cooled with no fan, so it makes no noise; normal warmth appears under continuous load but it stays within safe thermal limits.

What must I already own to use this square yellow slim tip charger?

A Lenovo laptop or workstation that accepts a 20 V, 8.5 A square yellow slim tip connector and needs no more than 170 W.

Will this 170 W unit safely charge an older 135 W or 90 W ThinkPad?

Yes — the adapter negotiates 20 V at up to 8.5 A and automatically steps down to 135 W, 90 W or 65 W for compatible legacy models.
