Hey, I decided to try one of those magnetic charger cables and the associated dongles that stay in your phone and other devices. First, my smart phone is developing an issue with its data + charging port so I wanted a nearly permanent connection device to stay in it once I insured it had a good connection (to lengthen the service life of my phone) and I often find that I am trying to plug in devices to a cable located in a dark room.
So, I shopped a bit and purchased a kit with 4 cables with lighted magnetic ends and many tiny tips (dongles) to permanently plug into my devices. I plugged one into my phone and plugged the cable into my standard phone charger and voila! the end lit up in a pleasant blue light making it easy to find in any light and bringing it close to my phone caused it to magnetically zip over to the connection on my phone and form a good connection (good meaning the phone started charging at full charge rate).
I put one of these cables in my car and I have to admit that little bit of blue light really helps me find the desired end of the cable while not having to see the end to identify up or down on it to get a connection to my phone really helps too. I think this is a type of product that is well worth the investment and will significantly lengthen the service life of my phone while also making it easier and much safer to connect up in the car.
