4.0 out of 5 stars Won't charge an iPhone 5S, 12 Dec. 2013
Verified Purchase(What is this?)
This review is from: Vktech 12V to 5V 3A 15W Double USB DC-DC Buck Converter Step Down Module (Electronics)
Purchased this unit to hardwire my TomTom and iPhone mounts into the car. As we use more and more USB devices in a car I thought this device would be useful to hardwire two permanent device holders - one for the TomTom Go and the other my Brodit iPhone mount. The device powers the TomTom without any issues but would not charge the iPhone at all. I didn't even get the not charging message you usually get with the phone. I have a Bluetooth adapter in the car so I use it to also power that.

It has enabled me to tidy up some of the power cables in the car and for that I have found it useful.
