I've been looking for some PD capable USB C cables for various devices and spotted these which boast up to 100w, so should be suitable for most needs.
Similar quality braided cables are around £8 on Amazon, so provided you don't mind the wait these seem like great value.
Price is for 1m but you can get 2m cables for a few pennies more.Item is shipped from China, so expect a wait. Taxes and any applicable duty has been calculated at checkout.
