Because these chargers are powered by batteries, charging at Springs Junction isn't guaranteed. If the batteries run out, you won't be able to charge. We encourage you to check the amount of energy available in the batteries before you turn up.
Maybe they should be limiting the amount of charge that can be drawn, so that people can get from there to Murchison, Reefton or Hanmer Springs rather than all teh way to their destination. It would be a bit crap if you got there in the afternoon and a Tesla driver had drained it.
Edit: just seen that only 164kWh is available !. Crikey.
