I might as well start with the Band Car Charger. I have to say that I admire its design. Instead of a single wire, this has a flat design which makes it really cool and flexible. You can actually charge two mobile devices with this Band, as there is a USB port on the car charger side and, depending what version you buy, it has the 30-pin connector or micro-USB. You can get it in many colors like Black, Blue, Green, and Red, each for $39.99 here.
Of course, it is pretty common to see a mobile charger, and this one can provide two full charges to most smartphones. In fact, it can even charge two mobile devices at the same time.
It has a 5200mAh Lithium-Ion battery, and it comes in a version with the 30-pin connector and the micro USB. It only comes in green and black, and it can be purchased for the iPhone’s 30-pin connector ($74.99) or the micro USB ($69.99) here.
I’ll end with the last item, the Y-Charge. Yes, it is just a Y-shaped thing with a car charger and two USB ports on the forked end. Do I really need to tell you how it works? You can get it here for about $24.99 for the old version and $29.99 for version 4.2.
