Review on ⚡️ Otium Cigarette Lighter Splitter: Type-C 20W PD Fast USB C Car Charger & Dual QC 3.0 180W 2-Socket Car Adapter - Ideal for iPhone 12/11/11 Pro/X/8/7, Samsung, Google Pixel, GPS Dash Cam by Leroy Jacobs

Charger does not charge at QC3.0 speed as advertised, especially when using multiple phones. I tested my S21Ultra5G alone where it charged at around 60% per hour. However, when I plugged the OP85G into the second QC3.0 port, both phones were charging at around 30% per hour. I've checked at least a few times. If each port is independent, why does the loading speed slow down? I also tested 3 phones and the speed is about the same - 33% per hour. The car stops and runs. The charger is also difficult to plug in.
