However, you overlook one excellent quality of the power runner. The ability to switch volts. I loved that thing because I could run either my DAT which is 6 volt, or my jb3 which is 5 or my ua-5 which is 9. That power runner is the smartest taping purchase I have made and have been thinking of dumping the dvd battery for another power runner and using the dvd battery as a ua-5 backup.

Very true and a powerrunner makes it very easy to address your various devices' power needs. Question for you -- can the powerrunner supply different voltages simultaneously, or do you need one powerrunner per voltage need?
Note, however, that my initial email was responding to a request from a person looking for a nine volt solution only.
