Your laptop battery won't stall halfway through the afternoon with this Lenovo USB-C laptop adapter. It's a straightforward spare or replacement for IdeaPad, Thinkbook, ThinkPad and Yoga laptops, so you can keep the original at your desk at home and this spare in your bag for the train. It charges over USB-C, so there's no odd-shaped tip to hunt for when you're already running late. It also takes anything from 100V to 240V at the socket, which makes it handy for a trip abroad, as long as you pack the right plug adapter for the country you're visiting. Nothing to set up either, since it starts charging the moment you plug it in.
