Changing thread direction -- I've tried to keep up with this thread, but don't believe I've seen this answered clearly and succintly. I really like my 9volt lithium ion battery/ua5 combination and would like to use a 9volt lithium ion battery to power the ua5 as well.
Looking for an easy, straightforward solution.
Will the previously-mentioned wallmart cigarette lighter adaptor work to do this if fed 9 volts (instead of 12)?
If not, I have enough soldiering experience to hack a voltage regulator together myself. What parts should I buy and where can I get them -- links are fine?
Finally, anybody running a ua5/jb3 off of a single wallmart 9volt lithium ion battery? If so, what are your runtimes?
