I've changed to using Apple's new USB-C cable, specifically the new 1m woven one (https://www.apple.com/shop/product/MQKJ3AM/A/60w-usb-c-charge-cable-1-m) for charging my laptop. It's far lighter than any other cable I've tested and coils very nicely. I have two of these cables and connect them with a USB-C female to female adapter like this (https://www.amazon.com/gp/product/B0BN3NH57G/) to make a 2m length cable when I need the extra reach for a power outlet. Also having two cables gives me redundancy and is useful for charging other devices at the same time (all my devices are now USB-C). I've been really happy with this setup, which is both overall lighter than the Anker cables and more flexible for my charging needs.

I like the looks of the CIO Novaport Duo 45W Charger - I'll have to go looking for that the next time I make it over to Japan!
