The phone holder is not a charger, but you can easily connect a cable by flipping your phone on its side or upside down in the phone holder.
I tried several design iterations of the phone holder that allowed a cable to pass through it, but each one had challenges that turned it into a bulky piece and a mediocre solution.
The only way to solve this would be to make it work for just iPhones, but since Apple changes things so frequently it could quickly become outdated. I chose to go back to the simplest, cleanest solution and make it just an awesome, timeless stand.
Maybe in the future I'll design a separate docking station piece that magnetically attaches to the base and doesn't compromise the design or functionality.
