I plug my upgraded Pro-18 into my tired old Dell D630 so that I can use Pro96com and Unitrunker. But I don't have the scanner set to charge. And it will drain the laptops battery. I wouldn't recommend it for a very long period of time.
Ahmen!!! From your mouth to gods ears! I've been screaming at these companies for years to make the dang things with battery packs and drop in chargers. People should be jailed for using AA batteries for anything!
