Review on Innergie 65U Universal Laptop Charger: Compact and Lightweight ⚡ Power Adapter Compatible with Acer, ASUS, Dell, HP, Lenovo & More by Kathy Morales

Didn't fit any of my devices 65 watts or less; a few old/new laptops and a few NUCs - before you criticize me (I know it's not a laptop but it should still work as a 19V 45W PSU). It's really super tiny (reason to buy) BUT it's annoying that you have to go to a website and ask for free tips and choose from a list (which didn't exist on any of my laptops, btw). You wait for something to arrive, you unpack and want to use it. Why couldn't they give more general advice there? For example, the hugely popular 5.5mm barrel sockets (2.1 and 2.5mm ID) are not here. Is it just a way to collect "registration" (er, personal) information? Because they ask for the name, address and serial number of the item purchased. In any case, it's sitting in the box until I find a use for it.
