Review on 🔌 63W Car Charger with USB-C PD2 (45W) and USB-A QC3 (18W) for MacBook, Google Pixel, iPad, iPhone, Android, Nintendo Switch, and More by Scott Tompkins

-- 15V and 20V outputs no problem. Most other devices in the Revain search results cannot do this. I have two and have used them on several trips. I charge my laptop with a cable that converts USB Type-C to Surface Connect at 15V 3A. I charge my power station with a cable that converts USB Type-C to DC 5.5 x 2.1 at 15V 3A. There was no overheating. The connection sometimes loosens, so you need to check it, but that's to be expected with car chargers. -- Also works great with 9-12V input. The specified input is 12-18 V. My power supply outputs less than the nominal voltage of 12 V, depending on the state of charge of the lithium cells. There are also losses due to resistances in batteries and cables. At less than 9V it won't provide the full 20V, but chances are your device requesting 20V will still work. The test result is below for the test in the picture. Input 8.35 V -> max. output 19.5 V (at 2 A) Input 8.12 V -> max. output 18.8 V (at 2 A) Input 7.25 V -> max. output 16, 9V (at 2A) - USB Type-C and normal USB independent. I get annoyed with devices that have some kind of combined limit on multiple ports. I don't like the look of the device. Not a big deal since I only use it occasionally.
