  PRODUCT OVERVIEW

Keep your ThinkPad or Legion powered and charging at full speed with this genuine Lenovo 135W Slim Tip AC adapter. Rated at 20V / 6.75A / 135W, it performs to the exact same specification as the charger originally supplied with high-performance ThinkPad P-series, T-series, W-series and X1 Extreme laptops – so your machine charges quickly, runs on mains power without CPU/GPU throttling, and shows no "attached AC adapter cannot be identified" warning. The universal 100–240V input makes it ideal for travel, and the slim, lightweight housing slips easily into a laptop bag as a spare charger for home, office or on the road. Fitted with the rectangular Lenovo "Slim Tip" plug (the USB-shaped connector with a centre pin), not the older round barrel tip.

·         ✔ Genuine Lenovo OEM part – exact factory 135W specification, not a low-cost imitation.

·         ✔ 20V DC output, 6.75A, 135W maximum – full power for P-series and X1 Extreme workloads.

·         ✔ Universal AC input 100–240V, 50/60Hz – works worldwide with the correct mains lead.

·         ✔ Rectangular Slim Tip connector – fits 2013-onward ThinkPad, IdeaPad, Legion and Yoga models.

·         ✔ Built-in over-voltage, over-current, short-circuit and over-temperature protection.

·         ✔ Energy Star rated for efficient, cool-running operation.

·         ✔ Slim and light – the perfect spare or replacement charger for travel and the office.

Check your existing charger or the socket on your laptop: this adapter has the rectangular Slim Tip plug. It does NOT fit older ThinkPads that use the round barrel connector with a coloured centre. Lower-wattage Slim Tip laptops (45W / 65W / 90W) can also use this 135W unit safely – the laptop only draws the power it needs.

Slim Tip vs round barrel – make sure your laptop uses the rectangular plug before ordering
