I ordered this item together with a charging cable that measures voltage output. I never got more than 9 volts of charging power to my phone from it. So it works, but the one I got is definitely not a fast charger.

Super fast charging

Does not sustain 100w charge for more then 20 minutes. Dont use on a laptop that draws a lot of power with thunderbolt, the adapter will heat up and self throttle, hot enough to almost burn yourself when you touch it. Look else where 100w USBC consistent charging.

I purchased this charger because I was having problem with my, this charger work perfect and changed the phone fast.

First off, I dont know if I bought this one by accident or the other one. With Amazon, its easy to get lost in the millions of items with similar characteristics however, after receiving two different car adapters let me say this. This adapter is incredibly well constructed. Had I not had the opportunity to compare this one side by side to another, I would have just taken this unit to be just another run of the mill car adapter. Let me be crystal clear here. This was NOT some generic one of a million other rebranded copy cat car chargers. Lets get to the positives. The construction of this unit is grade a quality. The unit emits a subtle glow on the ring of the unit when power is applied. You can tell the engineers that developed this unit took the time to add a little extra flair and it shows. The ports were very sturdy. Plugging in my macbook, steam deck and power bank in to the unit just simply worked. All devices were happily refilling their reserves and none of my electronics threw up any slow charging nags. Everything just worked. The unit remained cool to the touch and I have had zero issues over the past month. As someone who had ordered multiple units from different makers on accident, I can say with confidence that the quality of this one is superior in every aspect. I am planning to return the other one and get another one of these. Im so glad I lucked out on picking this one.

Charges my devices during commute fast..

be sure you know your current and future needs for power

This thing is amazing. I run power hungry devices with ease. It has no problem keeping up with my 17 inch 240hz laptop in usbc. The laptop is limited to 100 watts instead of the 180 it gets from the wall but this has no problem supplying the power. And it charges my fold 4 and s10+ at the same time no problem. Love it.

This charged at about 1% a minute. Its fast and reliable, not much else to say

I tested this at home with my power hungry Dell XPS 17 (came with a 130Watt Power supply) and it was charging at the full rate. Im currently on a road trip and it is powering my S9 phone at full speed and charging both work laptops (Dell latitude 5410 and HP ProBook) all at the same time.
