This retractable 100W USB-C cable is the best $10 you’ll spend on Prime Day

This year’s Prime Day isn’t showing that much cool stuff at surprisingly low prices, but it’s still a great time to snatch various high-value cables. Right now, Amazon is selling this Baseus 100W USB-C cable for just $9.94, matching its all-time lowest price. The key difference with this cable? It’s retractable, meaning it’s ultra-compact.

Instead of coiling this cable up like you normally would, you can just pull on either end to extend it to whatever length you need, then pull on it again to collapse it back down. It has several preset lengths, starting at 1.1 feet and going up to 3.3 feet—use the short end for when you’re tethered to a power bank, the long end when you’re at your desk and plugged into a charging station or power strip. Weighing just 0.11 pounds, it will barelly register in your bag or pocket.

And with up to 100W of charging power, it’s fast enough to fully recharge a modern phone in about half an hour. The downside here is that it isn’t good for data transfers—while it can transfer at up to 480 Mbps, that only makes it good in a pinch and not as a daily transfer cable. It’s also not fast enough for USB-C video, say between a laptop and monitor.

This is a great Prime Day deal, especially if you only have $10 and want to get something that’s both useful and unique. If you want to keep shopping around, see our picks for the best Prime Day deals under $10.
