I received the Boost X in February, including a USB-C fast charging cable, but beware, the fast charging cable can only be used for the Noco, not to charge a tablet or laptop directly! I have used the Boost X several times and it works perfectly.

I ordered the device almost 6 months ago. At that time, the cable was included.
Apart from that, I can say that I have only used the device once so far to start a colleague's motorbike (a larger chopper). The battery of the Noco was charged in December, left in the car until April, then the motorbike was started in a few seconds without any problems.

Kind regards
