Dear Bruce,

I own a Century Electri-pac Model BPIP-99 (Portable Electric Power -
Cordless and Rechargeable) which meets all your requirements. I bought
it several years ago from THE SPORTSMAN'S GUIDE catalog ($75.00 at the
time). I do not know if this model is still available, but you could
investigate. Similar items are available at THE PEP BOYS.

In fact I have powered my AOR AR7030 Plus and my Wellbrook ALA 330S
from this unit. Everything worked fine.

Best,

Joe
