The trouble with USB-C laptops or PCs is that so many don’t work with the older USB devices. All owners of USB-C computers will probably need an adapter (with multiple and varied ports) to plug in all sorts of things from USB memory sticks, to Ethernet, keyboards, projectors and SD cards. We have tested many and rounded them up into our best USB-C adapter feature. This Cyber Monday, there are some great deals on these so you can pick up a handy adapter at a fraction of the cost you’ll find them the rest of the year. Satechi, for example, is offering big discounts of around 30% off in its Black Friday Sale, although UK buyers need to buy a couple of items (totalling at least $100) to avoid international shipping costs. But fear not, we are here to help you save money. The Satechi Slim Aluminum Type-C Multi-Port Adapter V2 is discounted to $48.99 from $69.99 (a 30% saving) at the Satechi store. The adapter adds a micro/SD card reader, USB-C Power Delivery (PD), 4K HDMI and USB 3.0 ports, all from its single USB-C port. If you need an adapter at the very lowest price, Ugreen has a couple that will save you big time.
