This will tell you which types of “fast charging” Power Delivery a cable will handle and if the cable supports data, and will identify some types of electrical faults https://treedix.com/products/treedix-usb-cable-tester-usb-c-cable-tester-usb-tester-for-data-transmission-and-power-transmission-cable-testing-resistor-testing-type-c-emarker-for-usb-a-micro-b-micro-b-3-0-type-c-lighting-mini-b
And this kind of thing will tell you how much power is actually being transferred (but nothing about data transfer) - as someone else mentions, this also depends on the device you’re charging/powering, and the power source, but it is a more immediately useful number than what specification is supported: https://www.aliexpress.us/item/3256807855183284.html?browser_id=c9623fd12fa5452c9941ee83c4bcb933&m_page_id=jrd5irtoihqcaaw419fcdda6dc0206069af12e5513

Just to counterbalance some of the other (kinda wild) responses, weed dependency is a thing, weed withdrawal is a thing, and it’s not always as easy as “don’t go to the place”.
When I was heavily self-medicating with weed I did what others have said and tried to find it at my destination, almost always successful (did get scammed a couple of times but hey them’s the breaks trying to buy an illegal substance as a tourist, and at least it wasn’t worse). The one time I went somewhere I knew 100% I wasn’t going to find it, I got a wax pen and some shatter - it wasn’t the same (and never has been) as smoking it, but it worked OK enough
