About 7 power.
I quote: Compatible with USB-C smartphones, tablets, and laptops. Assuming that the Macbook Pro and Lenovo X1 Carbon are laptops, nothing should get in the way of the charging experience?
No problems on my side. I have an Aukey Quickcharge / Ai Charge with Aukey cables, everything works fine. The only problem with the Aukey cables is that the edge of the plug is quite thick and doesn't fit perfectly on my smartphone with a thick shell (so it disconnects in the car with the vibrations, but on a table no problem 😉 )
Just like the picture, 5.
Different lenght. Do not remember them exactly, 2 long 1 medium and one short if I remember correctly.
Cable quality is great. A bit stiff but nothing that bothered me.
The description says 2m*1, 1m*3, 0.33m*1. It's just written a bit silly (with the quantity after the item).
So the description matches the picture and the actual product is also like that, so 1x 2m, 3x 1m, 1x 0.33m.
