Only 45W, so OP’s will work better for large laptops, assuming there are big thinkpads using this connector (I have no idea if that’s the case)

- cptskippy 7y agoI think 45W was the max for laptops and the larger supplies shipped are for driving Docks. That being said ... Newer Lenovo Laptops come with 65w USB-C. The Docks however still use Slim Tip and go up to 90w. So Idk.
- chx 7y agoThe slim plug is available on adapters from 45w to monster 230w (that RTX 5000 in the P53 alone eats 110W, the CPU is nominally 45W but in reality it's oh-my-god then there's a screen to power, typically 4K and we didn't even start charging our battery, previously only the 17" laptops needed 230W at full config, the basic adapter is "only" 170W). The plug center leg is for wattage detection, there's a resistor to ground and the size of the resistor tells the laptop how many watts can it draw safely.
