At 6 and a half feet in length and as thick as a light duty power extension cord, this thing means business.
It is certainly capable of charging up to 140W, but I wasn't able to find anything that could handle anymore than that so I cannot speak to the 240W claim. The cable does glow toward the tip but its not bright and it hardly captures the imagination like the Aurora Borealis, I'm not sure I see a 'Stunning light effect'.
The reason you want this cable is because both ends have built-in adapters (the so-called 4-in-1).
USB-A pulls out on one end to reveal a USB-C, Lightning pulls out of the other end and reveals another USB-C, however there are a lot of cables on the market with this configuration and this one doesn't have the best build quality.
On first pulling out the lightning cable to get at the USB-C, the adapter practically came off in my hand. There is also a little more wobble than I like in the hardware.
This cable is inexpensive though and it does come with a nice zip up case to carry it around in.
For my taste it is too bulky and heavy for travel, but works out really nicely in my car.
