Comments on Smart 12V+ for Android

★★★★★ Awesome!! The main complaint is the permissions which it needs for it to function with the app. I just plugged it in and dl the app, and it was working. You can change the color and make it dimmer. Also tells you the output of each port and tells you the. Car battery voltage. That's probably one of my favorite features since I tow cars and many times I just have to jump. This will make it easier to know if it's the battery or alternator! Cool!!

★★★★★ This charger & the app saved myself problems with the car battery. The car battery was about dead, called AAA, a new battery was installed 30/09/2020.

★★☆☆☆ Literally bought it for the Bluetooth. Doesn't even work. Won't connect at all....... waste of money. It tells you to follow instructions to connect, but their ain't no damn instructions to connect. Not with the product or on the app.

★★☆☆☆ Got it working with permissions DENIED as they should be! To get this app to work, enable your phone's location and Bluetooth. Plug the charger into a socket that's always hot. Pair the phone and charger. Install the app and grant it all the permissions it wants. The app will now actually work. Do what you need to, then go into your phone's settings, hit "apps", find the Smart 12V+ app and tap it. Force stop it and deny all its permissions. The light stays off til power is lost.
