In 2014, every car on the road should probably have two USB charging ports at the very minimum, and a good cradle to hold your phone at eye level when you use it as a GPS. If any of your vehicles don't meet these criteria, you can kill two birds with one stone for just $13 today.
All you have to do is add both the iClever 360 Degree rotation dash mount, and the iClever 18W dual USB charger to your Amazon cart, and use promo code YE2SUEVG at checkout to knock the combined price down from $19 to $13.
While the iClever wasn't selected as one of your five favorite smartphone car mounts , it does have a solid 4.3 star review average, and even at full price it's much cheaper than any of the nominees. The USB charger has a 4.6 star review average, and has enough juice to charge up an iPad at full speed. [Amazon]
Update: It looks like the dash mount is currently unavailable. There's a chance it may come back, so keep checking.
