OK, feeling like a bonehead. Originally unboxed and connected this device to my desktop power supply for a USB powersource. It did not have enough ampirage to charge my watch. I swaped that out before tossing, and found that the supplied power source worked just fine and the device charges both my phone and watch beautifully. So I'm a dope, the product is great, and I am here to correct the review! Given that said, my one gripe is that the adjustiblity of the mount is a bit limited. It's totally functional, but doesn't pivot 360 degrees, and does not telescope like I was expecting. Regardless, it is sleek, a huge space saver, and dejunkified my desktop a great deal. I would defintely buy another one of these. ORIGINAL REVIEW NOW RETRACTED: Annoying. Doesn’t operate as advertised. Watch charger totally inoperable. Mag charger does work. Very disappointing!

Would not work in my jeep

Color: Textured

This seems like a decent holder, however it is not universal as it would not fit in my jeep. Check to make sure you have the right kind of air vents for it. I could not get it to work for my vehicle as the vents are too wide.

Works great!

Color: Black, Color: Black

This is a very simple, lightweight phone mount. It works well, I’m surprised how securely it fits on the car vent. I’ve tried others and couldn’t get them to fit right. My phone slides into the top and fits nicely. It was easy to install.
