Not so much a review ...
I've always said in the past, what's to review.... It's a wall charger. Plug in n charge you're phone/device.
Now see these 2 pics, each using 2 different leads.
1, this is using a cheapish "standard" USBC/usb lead
2, this is using the new USBC/USBC lead
I'm charging a Samsung Galaxy S8, and these were done one after the other (see the time in top of pic).
Surprisingly, there is actually a noticeable difference, with the standard USBC lead, charging quicker.
Anyone understand this?
