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

I think they just messed up the units, 6.5Ah * 5V = 32.5Wh which seems reasonable from the 38.7Wh battery, as that's a total of 84% efficiency which is pretty typical for a power bank.

So it should say rated capacity = 32.5Wh.

Most battery banks advertise their raw cell Ah/mAh ratings, which of course isn't the effective Ah at 5V. It seems like Heltec tried listing both ratings here.

Yeah it seems like it. Cell capacity is fine in mAh but output energy should always be Wh
