Smartblades are small and lightweight, easily carried in your pocket. When you snap-on a battery and memory Smartblade, you add 3,600 mAh of battery capacity to your phone. That is over 10 hours more battery life. Expand your Smartphone's memory depending on your needs from 16GB, or 128GB. Further storage expansion is possible with the Smartblade's micro SD slot. Snap-off the Smartblade when you only need best-in-class drop protection. A smart alternative to a bulky battery case or battery pack.
