It also comically catches on fire when 100 watts is reached as a handy visual indicator.

At that price, I'm sure it doesn't actually work.

this is a great idea - but it's early days and needs improvement i'm sure it does work otherwise that transfer rate would be far higher. many of the commenters don't use PD on USB C. if they did they would understand and/or love this. my issue however is the fact the transfer rate is abysmal - especially if you're charging a laptop. one would have to have a separate USB C for file transfers/syncing...making just as much of a mess as a power cord. but it is a very handy troubleshooting tool. as for price, watt meters and tiny B&W lcds are dirt cheap so the pricing isn't unusual

I have some of their products, it's actually not bad. I can even say that they're quite good.
