This is great if you only need one outlet and you don't want the type that has a big knobby thing sticking out 3 inches or more. My 12V outlet is on the center console facing up near the shifter. This one fits flush and looks like it belongs there. Other ones used to snag the cord or have to be pushed back down a lot because they popped up during normal driving. Nothing's more frustrating than thinking you're charging while driving only to find out your device did not charge when you arrive. As for charging, this has Quick Charge 3.0 technology found in certain models of the devices from brands like Samsung, LG, etc. and is backwards compatible with earlier QC standards. It will also charge non-QC devices at a standard adaptable smart charge rate so almost any recent device is compatible.*** I've found it to work well with my LG G4 (which is QC 2.0). As with most QC chargers, this one charges faster when you begin with a very low charged device than it does going from say 85% to 100%. I've observed an initial charging rate of roughly 1% per minute, sometimes slightly more with my G4 from a single digit starting point which I find perfectly acceptable. ***Highly recommend that you check your device's specifications for QC compatibility. Non-QC devices will charge at standard (slower) smart charge rates. They will not charge at the faster QC speeds obtainable when QC compatible devices use QC chargers.
