USB-C to USB-A adapter
The world seems to be converging on USB-C as the universal standard, and I hope nobody invents a replacement once we get there. For now, I live in a mixed world of USB-C and USB-A gear. These tiny, inexpensive Syntech adapters are how I connect the two: a male USB-C plug on one end, a female USB-A port on the other. I keep them on my desk and in my travel bag for flash drives, charging cables, wired mice, and other older peripherals. I've tried a few brands; this one is the most reliable, with nearly 189,000 reviews and a 4.7-star average. — MF
