Satechi’s latest widget is a tiny square puck that charges either an Apple Watch or your AirPods. It’s either the best or the dumbest accessory ever.

Design-wise, the $50 Satechi USB-C Watch AirPods Charger is slim and compact. You can plug it into either an iPad Pro or a MacBook and, depending on which way you flip it, it’ll charge either your AirPods or your Watch. There’s really not much to complain about how small the charger is. It’s perfect for both travel and desktop use. The problem is, would you need such a thing at all?

So what’s going on with Apple’s chargers? Why are there at least four different wireless charging methods, plus a couple of wired solutions? Let’s take a look at this mess and see if we can figure out a way out.

There’s now a standard for charging gadgets. Modern phones, cameras, laptops, speakers, and more all feature USB-C ports, making them all easily chargeable with the same cable and AC adapter. The USB-C protocol even lets these gadgets tell you how much power they need, so it’s just as safe to use the same charger for a pair of AirPods as it is for a MacBook Pro.
