[QUOTE="chscag, post: 1886562, member: 46727"] You don't need to worry about the output or input voltage. All Apple Power supplies are universal, in other words, they can be used world wide. However, your older supply will need an adapter which you can purchase most anywhere. The older supply will work with your newer MBP (with the proper adapter) but will take longer to charge the battery on the 2019 model. The reason is the older supply has a lower output, thus, it will take longer to charge up your 2019 which has a larger capacity battery than the 2014 model. [/QUOTE]
