Product shipped promptly, arrived in perfect order and is working just fine. I bought this as a second power supply. My work laptop is a Lenovo T460p, 4-core i7, 32GB RAM, 512GB SSD, discrete Nvidia 940 2GB graphics. It shipped with a 135w power adapter, but that one lives at my office connected to a Lenovo UltraDock. At home, I still wanted a 135w power adapter for use there to fully support the quad-core cpu and discrete graphics (I have the 90w from the ultra dock but reserve that one for travel use only). I'm very pleased with this purchase and it meets my needs fine at about half the price that Lenovo's online store charges. Review: These are easily double the size of the 90w adapters - I have a Lenovo W541 laptop that uses a 170w AC adapter. If anyone's seen these before, they are huge!! These are easily double the size of the 90w adapters. Needless to say, the 170w adapter is very difficult to carry in a standard laptop bag due to the size. Welcome to the 135W AC Adapter. The W541 works great standalone. This adapter can also drive the 40a2 docking station with the W541 mounted. As for the size, it's just slightly smaller (1/2" on sides) enough that it fits and stores easier in a laptop bag. I do wish it were smaller like the 90w adapter. Weight and thickness is about the same with both adapters. ## Features - UPC: 887942927257 - Weight: 1.350 lbs - Power Plug Type: Type A 2-pin (North America) - Input Voltage: 120 volts of alternating current - Frequency Range: 60 hertz - Power Output: 135 watts, 18 volts, 7.5 amps - Main Power Connector Type: 2 Pin - Special Feature: Magnetic connector - Power Source Type: Corded Electric - Compatible Devices: Laptops ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B00WB048SM | | Amperage | 1.23 A | | Best Sellers Rank | #36,402 in Computers & Accessories ( See Top 100 in Computers & Accessories ) #4,957 in Laptop Chargers & Adapters | | Brand | Lenovo | | Built-In Media | ThinkPad 135W AC Adapter (Slim Tip), User's guide, AC power cord | | Compatible Devices | Lenovo ThinkPad Notebooks: T440p, T440p 20AN, T440p 20AW, T540p 20BE, T540p 20BF | | Compatible Power Plug Type | Type A - 2 pin (North American) | | Connectivity Technology | Proprietary 2-Pin | | Connector Type | 2-Pin | | Current | AC | | Current Rating | 7.5 A | | Customer Reviews | 4.2 out of 5 stars 109 Reviews | | EU Spare Part Availability Duration | 1 years | | Enclosure Material | Plastic | | Form Factor | Rectangular Block with Power Cord and Connector | | Frequency Range | 60 hertz | | Included Components | ThinkPad 135W AC Adapter (Slim Tip), User's guide, AC power cord | | Input Voltage | 240 volts | | Item Weight | 476 g | | Main Power Connector Type | 2 Pin | | Manufacturer | Lenovo | | Mfr Part Number | B00WB048SM | | Model Number | B00WB048SM | | Mounting Type | Wall Mount | | Number of Items | 1 | | Number of Power Levels | 1 | | Output Current | 1.23 A | | Output Voltage | 18 volts | | Plug Type | A | | Power Plug | Type A - 2 pin (North American) | | Power Source | Corded Electric | | Special Feature | Magnetic | | Special Features | Magnetic | | UPC | 700814660239 700814660253 700814660246 012302369457 | | Unit Count | 1 Count | | Warranty Description | 30 days replacement or refund | | Wattage | 135 watts | ## Product Details - **Brand:** Lenovo - **Connector Type:** 2-Pin - **Compatible Devices:** Lenovo ThinkPad Notebooks:, , T440p, T440p 20AN, T440p 20AW, T540p 20BE, T540p 20BF - **Included Components:** ThinkPad 135W AC Adapter (Slim Tip), User's guide, AC power cord - **Input Voltage:** 240 Volts - **Amperage:** 1.23 Amps - **Wattage:** 135 watts - **Number of Items:** 1 - **Output Current:** 1.23 Amps - **Output Voltage:** 18 Volts ## Images ![Lenovo 135W Slim Tip AC Adapter ( 4x20e50558, Retail Packaged Lenovo Originals ) - Image 1](https://m.media-amazon.com/images/I/51Z5L3H5IhL.jpg) ![Lenovo 135W Slim Tip AC Adapter ( 4x20e50558, Retail Packaged Lenovo Originals ) - Image 2](https://m.media-amazon.com/images/I/51hOPLFFebL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Not much to say other than all good. Product shipped promptly *by M***C on December 6, 2016* Not much to say other than all good. Product shipped promptly, arrived in perfect order and is working just fine.

If anyone's seen these before, they are huge!! These are easily double the size of the 90w adapters.

I do wish it were smaller like the 90w adapter. Weight and thickness is about the same with both adapters. ### ⭐⭐⭐⭐⭐ It works. *by P***R on February 18, 2015* I got a Lenovo Y50-70 gaming Laptop and I had lost the charger. I was using the iTEKIRO Laptop Charger AC Adapter for Lenovo for like 3 months but it's huge and everytime I plugged it in, my laptop would announce that it wasn't compatible with it. It still worked but I wanted the original slim one again. The Lenovo website only seems to be selling them at 100 bux though which is ridicules. Here on Amazon I found it a lot cheaper and it works perfectly so far. No warning messages, it just plugs in and works like it should. ## Frequently Bought Together - Lenovo 135W Slim Tip AC Adapter ( 4x20e50558, Retail Packaged Lenovo Originals ) - Lenovo USB-C Cable 1m - Lenovo ThinkPad Universal USB-C Dock-40AY0090 --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.us/products/15085920-lenovo-135w-slim-tip-ac-adapter-4x20e50558-retail-packaged-lenovo](https://www.desertcart.us/products/15085920-lenovo-135w-slim-tip-ac-adapter-4x20e50558-retail-packaged-lenovo) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-10-04*
