Car Models compatibility

One major cons that we had observe is that, the total contact conductive electrode design of Roidmi 2S. It have some compatibility issue with some of the cars model and some buyers may find out their car is not under the supported models.

For cars that have the straight-through type cigarette hole which makes the Roidmi 2S unable to fit snuggly in the hole. So when the car vibrate or go through some bump it will get disconnected. But there is one simple workaround for this, you may just insert a small piece of paper to the side of the USB charger and it will fit nicely without affecting the connection.  

They specially design a adapter for the incompatible cars too which you need to purchase separately or you may just use a piece of paper to see if it works for you.
