About a year ago, I bought the LPS in the link below on eBay to power the 13" MacBook that I was using to play hi-res files from Roon, and had the seller alter it to output 16.5V DC, as that is the voltage required for the 13" MacBooks. The laptop recently died, and I am using a newer 15" MacBook with retina display that is supposed to have 20V DC input. Is there a simple/straightforward way to modify the LPS I already have to get it to output 20V DC rather than 16.5 DC? I plugged the LPS (outputting 16.5V DV) into the new MacBook and the charging light comes on on the Mac and the battery charges, so it seems to be working, but I am concerned that it may not be ideal to run it with so much less DC voltage than the stock MagSafe charger normally supplies. I would be grateful for any help/advice. Thanks so much! Chris https://www.ebay.com/itm/111981585534 |
