Review on SlimQ 100W USB C Charger: GaNFast Tech, Fast Charging for MacBook Pro/Air, iPad Pro, iPhone 13/12/11/Pro Max/XR/XS/X, Galaxy, Pixel, Laptop, and More! by Sirious Cavalli

I've tried at least six chargers in the last week and this charger was by far the best. Compact, great design and not too many power outages/dropouts when adding or removing a device on any of the ports. However, I had two problems. The USB-A port charged my Samsung phone at 9 volts when I added an iPad to charge via the USB-A port. Samsung connector voltage is calibrated to 5V, which is normal. However, when the iPad was removed from the USB-A port, the Samsung A port should rise to 9V (multiple test instances), but it didn't, resulting in a recalibration error.2. I was able to charge 2 HP laptops successfully (at 20V, peak power 35W and 25W respectively). In my opinion, a laptop with a USB-c1 port should have had better performance. As soon as a second laptop is added, the charger emits an awful squeaky, high-pitched noise, which can definitely be annoying when you're trying to fall asleep at night. Hence the 1 star. I cannot recommend this charger.
