Good product and good quality, claims to have charging technology that doesn't overheat much but I found it heats up as much as a charger I have that is original from Samsung. In reality, the charger delivers up to 40W divided between the USB and Type-C ports of the charger, but it doesn't deliver 40W all at once. In fact, I use a power bank on my phone and it charges faster than using this Kuulaa charger. So if you're looking for a charger that truly delivers the 40W, look for another option. In general, I liked it; the power supply is heavy and the cable is of quality, but it doesn't deliver the 40w all at once.
