Review on [Updated Version]QUICK CHARGE 3.0 Cigarette Lighter Adapter: Powerful 120W 12V/24V 3-Socket Power Splitter with 8.5A 4 USB Ports. Multifunction Car Charger with LED Display Voltage and Upgraded On-Off Switch - Latest Upgrades! by William Gildea

I like this charger very much. I drive a 1998 car so it only has a 12v plug and it's in a compartment that can only be opened by flipping the cup holders and the compartment is small so most chargers won't fit, when it is closed, and many others. when a cable comes out, leave it open. This charger allows me to leave the main plug in and on, and that compartment is almost always closed. I used glue to conveniently install the charger to the side of the cup holder. When I'm not using the car, I turn off all 3 ports and plug in the charging cables. When I start the car, I press 2 buttons and 1 - my phone cable and micro USB are powered. 2-My Bluetooth radio turns on and automatically connects to my phone and I can play music. 3-My dash cam will automatically turn on and start recording. The buttons allow me to leave everything as I want and not have to worry about the battery dying, except for the main power/battery indicator (which is VERY useful, especially if you spend a lot of time in one place at which is not jumped is important). option in winter) which I leave on for the sake of simplicity because it consumes very little power. Despite all that, I still have a spare 12 volt outlet and 4 USB outlets, perfect for the back seat passengers to charge their phones. There are many other products of this type at Revain but this is the only one I've found that comes with 3 12 volt and 4 USB chargers, a small main charging plug, a main switch, a battery indicator, a long extension cord and a removable adhesive plate with additional glue and fuses . All at a great price. If you are looking for something similar, buy it!
