The TP-Link UC400 is a short USB-C (male) to USB-A 3.0 (female) adapter cable that lets you plug ordinary USB devices - flash drives, external hard drives, card readers, keyboards and mice - into a laptop, tablet or phone that only has USB-C ports. It runs at USB 3.0 SuperSpeed (up to 5 Gbps) and falls back to USB 2.0/1.1 for older devices. OTG (On-The-Go) is supported, so on an Android 6.0+ phone or tablet you can copy photos straight off a card reader or memory stick. TP-Link lists compatibility with Windows, macOS, Chrome OS, Linux and Android, with no drivers needed. The white adapter has a roughly 13 cm cable, measures about 50 x 14.5 x 73.5 mm and weighs around 40 g, so it lives happily in a laptop bag. It's a cheap fix for new MacBooks, USB-C ultrabooks and Chromebooks. In the box: one UC400 adapter.
