The Spinner IIIS has seen a lot of improvements since the original came out.  The battery is a twist variable voltage that runs from 3.6V to 4.8V.  The top ring above the button twists to allow you to choose the voltage level that you like.  The Spinner IIIS packs a whopping 1600mAh of battery capacity to give you all day performance.  The Micro-USB charging makes keeping the battery charged a breeze and the color of the light in the button tells you where your charge level is at.  This is not a Vision product.  Please note that a charging cable is not included with this product, but any Micro-USB (Android power cable) will worked when plugged into a 1 amp power block.  We do not recommend using fast chargers or anything over 1 amp to prevent damage to the battery.
