Seems like Aukey is competing with the Anker deal!
On sale for $39.99 minus $15 coupon to 'clip' on Amazon = $24.99 w/ free prime shipping which is $5 below lowest CCC price ever.
This charger can deliver the full 60W on a single port (unlike some chargers that only do 45W) so this will power most USB-C laptops up to 14" and even some 15".
Note: two USB-C ports, no USB-A on this one.
GaN technology isn't anything relevant to the computer itself, just allows for physically smaller chargers.
