How is the Slim Case different than a traditional protective case?
The Slim Case doubles as a traditional protective case and, when needed, a power case. The Slim Case is the thinnest battery enabled case on the market and allows you to conveniently add a Smart Battery to your device when you need it and remove it when you don’t!
Will this case work with all iPhone 4 models?
Yes, this case is designed to work with all models of the iPhone 4.
Can I charge and sync my iPhone without removing my case?
Yes! You can charge/sync your iPhone using the included micro-USB cable.
What are the two ports on the Smart Battery?
Your Smart Battery features a USB-In port, labeled "IN", to provide charge to the Smart Battery and a USB-Out port, labeled "OUT", to provide charge to a variety of other devices.
What is the best way to charge both my Smart Battery and my iPhone?
Using one outlet, you can charge both your iPhone and your Smart Battery. Simply plug the included micro USB cord into the USB port on the Slim Case, attach a Smart Battery and charge on! You can even charge other devices (i.e. Bluetooth headset) via the USB-out on the Smart Battery using the same outlet to create the ultimate powerhub.
What are the three gold rails on my Slim Case and Smart Battery?
We have created the unique Third Rail™ System to seamlessly transfer power without the need for cords. When you attach a Smart Battery to your Slim Case, power is seamlessly transferred via the gold rails.
