Review on StarTech.com Dual Port Car Charger with Lightning Cable and USB Port – High Power (21 Watt / 4.2 Amp) - Dual iPad Car Charger - Black - Fast Charging for Multiple Devices on the Go by Joshua Beaule

The StarTech Dual Port Car Charger is a great way to simultaneously charge your iPhone and iPad using just one of your car's accessory ports. WHAT I LOVE The charger and cable are very well made and have a blue light to show the device is on. The extra charging port is very handy when there is a passenger in the car, as you only need the cable itself and you can charge a second device. I actually keep a basic Lightning cable in the car in case one of my kids needs to charge their iPhone or iPad so I don't have to unplug my phone. This is a high power iPad charger version that charges iPhone. very fast. I like this because I only really charge my phone when I'm in the car or at home at night and it instantly increases battery life by 20%. This is a great way to get a lot more battery, even if you're just running to and from lunch. WHAT I DON'T LIKE The only thing I don't really like about this cable is that it's pretty finicky. I find the cable could be a little longer or the spool a little looser. The coiled portion of the cable is fairly tight and doesn't give much, so the cable is about 12 inches long. I don't really care because I usually keep my phone in a small tray right in front of the charger and it's nice that there aren't long cables hanging around everywhere. However, when I pick up my phone and want to look at it, just move from the console to the normal position, holding and looking at the phone pulls on the spiral part, and it's quite tight. If you're the pick-and-drop phone type of person, this will work great for you. If you use your device in the car (hopefully not while driving! ), the cable might be a bit short.
