Switch to USB PowerConnect+ from Kurt Adler and never use batteries again! This PowerConnect+ product contains molded plastic “battery shells” which have no cells or chemical content. They act as a conduit for the power providing the contact required within the battery box and the USB connector, and they never need recharging. These shells fit into the battery compartment of your device the same way as a standard AA sized battery. Use this PowerConnect+ for any product requiring 2 AA batteries and never worry about changing batteries again!
