The PalmPower Plug & Play is USB powered and requires no batteries! Unlike the Original PalmPower, the PalmPower Plug & Play can be powered anytime and anywhere through the portable power bank included with this pack. The PalmPower power bank has a power of 2600mAh and comes in a pretty fuchsia colour. There is 8" USB cord attached to the PalmPower for more mobility. The PalmPower Plug & Play works with all current PalmPower Attachments using the "T" lock guide to keep the attachments secure and in place during use. Easily pop the removable silicone head off and replace with any other Palmpower attachment for different sensations.
