Well this is interesting. Stick-a-node to any smartphone with magnetic back. I could see myself trying this.

    Well, your phone needs at least 5 volts. So it sounds to me as though if you’re using the node, then it can take advantage of the entire battery. But if you’re using it to charge your phone, you can only take advantage of like 70% of the battery.
