Not bad... But 550mAh is more 10% or less of a modern phone battery after some inefficiency is considered.
But interesting idea indeed.

enough in a pinch to get a call or some texts out order a rideshare/taxi from the bar etc. this would be more useful for topping up a rechargeable flashlight or... your other vapes.
Though back in the day I was doing exactly the opposite of this 🙃
I don’t know why this is such an appealing project, but it is. Adding an LED and a switch so it can be used as an emergency flashlight would be cool too.
