Question to seller: why does the title say "linear" ? can not be both switching & linear -violates amazon policy false advertising. pls correct this.

It’s a linear power supply because it uses a voltage regulator to set the voltage. Which is most common in linear power supplies. In this case, it is a adjustable voltage regulator with a potentiometer that changes the voltage, From 0 to 30V. A switching power supply uses pulse width modulation to create the desired voltage.

Can i get another copy of the jesverty wps-3010 user manual? believe it or not, my bichon ate it within 30 minutes of opening it.

Is amperage maxed at 5a regardless of voltage? i'm wondering how many watts i can get max at 12v. above 12v 5a = 60w or no?

Yes, for WPS-3005, the maximum current output is 5A and you get 60W max at 12V 5A. If you need more current at 12V, we suggest you choose 10A model, WPS-3010.
