SAME HERE! I have THREE Sonic Ports,..... two of the 2nd version and one of the 1st version. I've use them on an iPhone 5, iPhone 8, iPad Pro 12.9, and iPad 5.... They used to charge, slowly but they did. Now they don't even register that they're plugged into power. The Sonic Ports work fine BUT they're SUCKING UP the iOS devices' power. Kind of a bummer!
