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

    It seems those ratings are the internal battery size at 3.7v, and then the 6,500mAh is the actual capacity at 5V.

      I think their marketing just screwed up, they’re supposed to rate output in Wh, not Ah.

      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.

          That’s the standard - listing the raw cell Ah - and it always has been dodgy. I guess in this context ironically it seems more dodgy because they also list the effective capacity. :D
