For those interested..so far so good..looks like we have another alternative to the Wal-Mart rechargable Li-Ion battery.
Unit comes w/ a switching mode AC adapter, 12V car lighter charger (good for between shows on the road), power cable and various tips (none of which work w/ the UA-5), and the 9.2V 2600mAh Li-Ion battery complete w/ LED charge display. The battery can't be more than .50 lbs, so its light and compact.
Just charged the batt up - @ 4hrs for a full charge, even though it had a bit of juice fresh out of the box...
Connected it w/ the Ratshack custom cable:

...for my needs, this will do fine I think
