power adapter help
I have gotten a mid2010 macbook pro. It's power adapter voltage is 16.5 volts and 3.5 amps. But i didn't get the power supply and i do have the power cord from the macbook to the power adapter. I have a choice of 3 power adapter i can use from old laptops i have. One has a output of 15.9 volts and 3.6 amps and the outer one puts out 19 volts and 2 amps and the last one is a universal ac adapter for laptops and i can pick voltage from 15 volts to 24 volts by a switch and lock it to that voltage and it puts out up to 6 amps. I just don't want to burn up the macbook. I don't have the money right now to get a power supply off ebay. I was think about putting a jack at the end of the power card for the macbook and plugin the universal adapter and setting to 16.5 volts. Does anyone have on what ones you would go with. This is only temporary until i get enough money to buy the right power adapter and my wife's ok to get it. that's going to be a so time since i paid $200.00 for this. Thanks for the help i get.
