I have that Anker wall port too, and it’s fantastic. I was sad Jackery stopped carrying the Bolt though, bc built in cables were a game changer until they wore out. I’ve found if I bring my Macbook (12”), usb-c to a lightning cable means I’m pretty well set to charge my beats x, or my iPhone from the MacBook wall adaptor.
Do you read on your iPad/iPhone? Or do you also bring a Kindle? I’m hoping they eventually support usb-c so I can ditch micro usb cables.
