I've had this charger for over a year. It works reliably well and it has the longest cable of all the plug-in type chargers I've found. So a few hints - 1. if you pair this to the app, it will go into a mode where you have to turn it on in the app before it starts charging. Super annoying. Fortunately, Vevor customer support gave the solution to this - \"Please press the ‘A’ button for 5s after unplugging the charging gun to switch to plug-and-play mode, no need to start charging through the app.\" That worked and it was back to the same automatic charging as before 2. The A and R buttons on the front are active. Not obvious because there is no touch feedback at all that indicates they are pressable. You need to press them to pair to the app (see manual for steps). However, even if you don't need the app, it's easy to accidentally press the buttons if you ever fuss with it. It becomes an issue if it changes how much current it draws. If it gets to be higher than what your circuit will allow, the device will not charge your car. If it's lower than what your circuit will allow then it's too slow. There is no indication on the device on what mode it is on. I check the app for the mode and set it there. Otherwise, check the manual for which button to set it to the right mode. 3. The \"brains\" of the charging unit plus the long cable are heavy vs other units so it will pull on the plug that attaches to the wall. I ended up wedging the main unit against the wall and the floor to remove the pull on the plug. All that said, I really really like the unit and it's been super reliable. Hopefully the learnings above help you out if you ever hit those issues.
