With simultaneous charging of multiple devices, it can cover all the passengers of a car for a trip and the additional accessories that someone may use (e.g. air compressor for tires or inflatables for the beach). Also, the adapter's cable for the cigarette lighter is quite thick and there is no risk of overheating in case of high load from the main device. Another positive aspect is that it has its own safety protection in case of overload or short circuit.

I mainly bought it to branch out my "lighter" sockets, but it doesn't do a proper job. It doesn't provide the correct currents, it loses a lot compared to what the car socket provides. My portable refrigerator with a compressor doesn't work almost at all when it's connected to it. It doesn't receive enough power to cool. Even without anything else connected to it, so you can say it draws power.
So, in order for the refrigerator to have a tendency to work, I had to remove this from the socket and plug the refrigerator directly into the "mother" socket. And now I have to see what I will do since I need other ports.

Very good quality. 3 separate buttons for intensity deactivation 3A. Small size. I am happy that I chose this Car Charger. It charges the device quickly.
