Here's something a little different. A 100W capable 3-in-1 retractable cable combining USB-C, Lightning and microUSB into the one cable. Baseus have dropped the price by 20% from their regular price that then stacks with the current eBay coupon codes OCT15/OCT17. It seems they've invested some time to produce a decent cable with a more robust retraction mechanism, which should mean it'll perform better than some I've used in the past that worked poorly and ended up getting binned. And being rated at 100W, you can use it to charge your USB-C laptop as well.
The claimed charging performance for various iPhones is:
iPhone 15:20W
iPhone 15 Plus:27W
iPhone 15 Pro:20W
iPhone 15 Pro Max:27W
I like the idea of it for my work travel to save juggling multiple cables and the fact you can charge using all three variants simultaneously.
Ebay plus members, use your monthly $5 code instead for better saving.
