bought a couple of these. https://www.amazon.com/dp/B0119EIHTG/ref=cm_sw_r_cp_api_HgBAybDDDBM59 We have a lot of iPhones and iPads in the household so we have a multitude of chargers lying around in each room. Will I be able to charge my MacBook with a iPhone or iPad charger? I know it'll be a lot slower but I just wanted to make sure that the voltage disparity won't damage the laptop. Also. I have one of those wall plugs that consist of theee wall plugs but also has two USB ports that you can directly plug in USB cables to. Same question. Could I plug in the USB A to C cable and charge my MacBook or will is the voltage too much and short out my comp?
