Turns out, having a laptop with only USB-C ports means you need to carry a dongle with you from time to time. Who knew? Luckily, these $15 hubs from VAVA ($15 clippable coupon + promo code KINJAVAHUB) are designed to perfectly match your MacBook, and turn one USB-C port into an ethernet port, an SD card reader, an HDMI output, and three USB 3.0 ports. There’s even pass-through USB-C charging, so you’re not even really using up one of your precious ports.
Note: Silver model only.
For comparison, the best previous deal we’ve seen on this hub was $27, which itself was pretty noteworthy. These things aren’t cheap! So if you have a USB-C-powered laptop (or even a phone or a tablet), and don’t already own something like this, I’d order it quickly before the deal goes kaput.
