Infinity Cable: different tips attach via strong magnets, allowing one cable to support USB-A, USB-C (including Power Delivery), Lightning and Micro-USB. That's all very like the UNO the difference is the promise of being able to charge a laptop as well as a phone or a fitness tracker. If you really like the cable, it's worth getting a few spare tips so you can use it with several devices without having to get the tip out each time. That leaves the tip in your device, so the little black tool for prising it out will come in handy unless you have strong nails. The magnets are strong - get the tip close to the cable and it snaps on securely, but if you yank on the cable the tip will come off before you pull your device off the table. The Infinity cable has USB-C on one end, with an optional ($5) USB-A adapter for when you need to use an older port the other end is a magnet with interchangeable connectors for USB-C, Micro-USB and Lightning.

But the big change is that it supports PD up to 100W. The £46/$55 Infinity Cable (also from Chargeasap) has some nice tweaks: a cord wrap a smaller, less bright LED on the cable so you know when power is flowing but you don't get dazzled by your phone cable at night and the 15-year warranty that presumably inspired the name. That's why the UNO interchangeable cable we looked at recently didn't support PD, making it an almost, but not quite, universal cable.

And you need specific controller chips in the cable to support PD. Different protocols have different licencing requirements, so not every cable supports Thunderbolt. Some laptops have one USB-C port that supports the PD (Power Delivery) standard and one that doesn't, because that way you can use a cheaper controller chip and only have to route the power down one path on the motherboard.
