Replacement AC Adapter for Lenovo IdeaPad Gaming 3

This 170W adapter replaces the original Lenovo 135W and 170W units for the IdeaPad Gaming 3 15ARH7 series. It powers the laptop and charges the battery whether the system is on or off. The unit is new and built for mobile use with a ruggedised case sealed against moisture and humidity. Buyers needing a 230W or 300W charger should look elsewhere.

Output Specification Decides Compatibility

The adapter delivers 20VDC at 8.5A for a maximum of 170W. Input accepts AC 100 to 240V at 50 to 60Hz for worldwide use. Comprehensive internal safety features filter voltage spikes and limit output voltage or current to protect the notebook from electrical hazards. High power efficiency provides consistent and continuous power for the laptop.

Cord Length and Build Give Practical Headroom

A 6 ft UL listed 3-prong AC cord plus a 6 ft DC cord give 12 ft total reach without extension leads. The case measures 6.18 x 3.31 x 1.97 inches and weighs 26.50 oz. Durability suits harsh mobile environments and tight sealing resists high humidity. The adapter does not support laptops requiring 230W or 300W input.

Questions about this item

What does the 170 W rating mean when the adapter is connected to my laptop?

The 170 W rating is the maximum continuous power the adapter can deliver at 20 V and 8.5 A, matching the original Lenovo 135 W and 170 W units so the laptop runs and charges at full speed.

What connector standard does this adapter use and what does it limit?

It uses the standard Lenovo rectangular DC plug that fits the IdeaPad Gaming 3 15ARH7; the 20 V 8.5 A output caps the power at 170 W, so it cannot replace 230 W or 300 W chargers.

What physical space and mounting clearance does the brick need?

The brick measures 6.18 x 3.31 x 1.97 inches and weighs 26.5 oz; the 6 ft AC cord and 6 ft DC cord give plenty of reach without an extension lead.
