[Galaxy S 4 Accessories] Hotbread:
Here's my mini review of the Scosche Power Mount:

I've always been a very picky user when it comes to car mounts. I generally hate the suction mount style because I think it'll fall off over time or the windshield glass is too far for my practical hand reach. I also hate the vent mounting system because... well... I want AC air flow. Then there's the cup holder mount... I like to use them for my actual drinks. Then there's the sticky pad mount... which I think gets dirty and loses its sticky pad property and that the dash is far from my reach.(I drive an SUV) So that leaves me with the cigarette lighter ports mount type, which has its own set of problems... Often times the mounting plug is round... so it will "spin slip" and sag your phone when set at an angle. Or that the plug offers such limited functionalities. So you can see my rationale in my picky-ness... lol

Then there's the flexible arm issue... sometimes the flexible arm is cheaply made and is too weak. The arm is too long/short/missing arm.

And... the holder cradle is bulky, non adjustable, no padding for phone, etc.....

But I have found this and am quite satisfied with it:

Let's go down my concerns and see how it addresses it. :P

- Plug has a triangular shape to help brace it against something to prevent "spin slip".

- Plug has 2 USB outputs PLUS the pass through cigarette lighter port. My friend can charge even if they bring their own fatty cigarette lighter plug charger.

- The flexible arm is made of tough bendable metal material and has the right length so the toughness can actually support the weight of the extended arm.

- The arm length is there but not super long. It's enough to extend phone to places around the dash from mounting port. I had to still crunch mine up (S curve) to fit because I didn't want it too far from the plug.

- The mounting cradle is a treat! It has a cool spring loaded mechanism to accommodate wide and narrow devices with click locking so it's actually secured.(squeeze in cradle arm to tighten on clicks. Push button in back to release and widen cradle arm.) The foam in the arms create the perfect soft squeeze to prevent slip. Well padded in all regions where your phone would come in contact with the cradle. It can spin 360 on a pre-determined clicks for portrait or landscape mounting. There are actually two little swivel "feet" that can either be hidden flush for landscape mode or extend to support phone when in portrait mode. (Tiny swivel feet are also soft padded!) The cradle is minimal in obstruction, so the common placements of ports on different phones are fully accessible.

I drive an Acura RDX so its a stiff ride and can feel the bumps of the road, which generally causes dangling items in the car such as the extended arm of a car mount to shake and rattle. I'm happy to say that I don't experience shakes on the car mount! Unless, of course, when I drive over large pot holes or go at high speed over speed bumps, which I would be more concerned about other things than my phone shaking in such instances. However, do note that my mounting arm is crunched up in an S shape and is not exactly dangling out like a fully extended mounting arm, so the shaking effect may have been reduced.

There are some drawbacks to this product though. (not everything is perfect)

- The USB ports only charge at 500mA per port, so it might be a tad low for some. However, in practical use, I find that it is enough to overcome the power drain of when I use Navigation and screen on all the time. So when I get out of the car, my phone had increased in charge %.

- It doesn't come with any cable, so you'll have to use your own. I find that the retractable cables work best for length adjustments.

I've been using this for over a year now. I used an iPhone 4 with it and now I'm using my Galaxy S4 with it.

I also bought one for my nephew as he had been complaining about his vent mounting cradle. He's very happy with it!

PS. I'm not in anyway affiliated with Scosche or benefit from advertising for them. I just feel that my search for a perfect car mount can satisfactory end with this device and I thought the OP of this post (or anyone in search of a car mount) could reap from the fruits of my... labor. lol :)
