I have tried it with a 65w to 20v adapter and it works great, I can charge my laptop in the car thanks to this. Also, the cable looks of good quality, I don’t know how long it will last charging the laptop but it looks good and works as described.
Customer –
Works as expected, “superfast charging” works with the corresponding cable.

Surprisingly good product. I was able to charge it up to 95W from the C1 port with a continuous current of 4.75A for several dozen minutes. The power supply had 11.7V and a draw of about 9A. I am sure that the charger will handle the declared power as long as the power supply maintains at least 12V. I sincerely recommend this product. It’s real GaN because the case doesn’t heat up significantly.

So far so good, looks beautiful, has some heft to it, feels and looks kinda premium, and it will charge my laptop while running, playing games and compiling source code, that was the test i gave it. I can’t prove it provides 100w, but my laptop uses only a 67w brick, and this had no difficulty powering it and charging it when under load, i tried to max it out anyway. The only thing left to test is longevity. My house charger from asomtech has been great for a year or more, so if it’s built to the same standard, i think i’m going to be pleased with it for years to come! Would recommend!

Two weeks to europe.charge laptop from 12v or 24v battery.

Among car chargers (12v input), I was looking for one that could charge a laptop (20v charging). I bought several third-party PD-supported chargers, but this was the only one that could charge my laptop (Lenovo) for around 10,000 won. Other than the disappointment that it doesn’t even have a battery voltage display, it’s a really satisfying product.
