OK, my ridiculous Radio Shack mixed up 'technician' story (He WAS supposed to be the 'expert'). A customer came in for a wall-wart, the 'tech' (who was the store manager) asked what the power requirements were and the customer said 200ma. The manager showed the customer a 150ma supply and said this will power the device with no problems. The customer then mentioned a friend told him the smallest wall-wart should be the device being powered (again 200ma) so he should be getting a minimum 200ma and since the 500ma wall-wart was the least expensive supply, that he should buy that one. The manager / tech then said if you buy that one it'll burn out your device since 500ma was 2 1/2 times too much power. After the customer left, I tried discussing the fact the wall-wart would supply UP TOO 500ma (give or take) and that the device would only draw as much as it needed of that maximum power and be totally satisfied but he stood fast with his expertise. I left that Radio Shack and never went back. They were already in decline (RS in general), and were maximizing push of cellphones and battery operated toys (mostly RC ones). I have little doubt the re-opening of RS will be disposable electronic/electric devices of a wide variety.
