Re: Astec AA9090A power supply

[Fred Townsend]

Unless you have some very strange laptop the power supply furnishes raw DC to the laptop down converter which charges the lap top battery. The laptop determines what kind of battery is used, not the plug in the wall power supply.

I have the one page spec sheet from Jameco, but it does not give this info.   Thanks, Brad
