IJoy's new Saturn Pod Kit features an integrated 1,100mAh battery, and can be charged via a micro USB cable. In addition, it's primarily constructed out of zinc alloy material, so it's both lightweight and durable. There is a small LED light indicator which will notify you of your current battery life. The actual light is embedded around the fire button, which is certainly a nice touch. Also, this pod kit does sport an ergonomic design, fitting comfortably in the palm of your hand.
