Review on Microsoft Surface Car Charger with 42W Power Supply - Compatible with Surface Pro 3/4/5/6, Surface Book, Surface Go, and Surface Laptop - Includes 5V 2.1A USB Charging Port and 5Ft Cord by John Brazington

I've bought three different car chargers and this is my favorite. We have a small blue LED that indicates the power is connected. It has a universal surface charging cable to charge my Surface Pro or Surface laptop. This output voltage is well regulated up to 2.58A. And with a USB fast charging cable it can quickly charge a smartphone (of course the phone is available for fast charging). The best part is that the socket can be controlled via the ON/OFF button. I prefer to sit on such a button to check the charge level. All in all I think this is a good choice for charging on the go and I would recommend it to my friends.
