I remember seeing somewhere an adapter for 510 socket that you screw in your mod and can charge a phone from it, maybe someone had it or know where to get it?
Never heard of that one. My battery chargers have a USB outlet that you can use to charge phones if you put in a charged battery. I generally have around a dozen charged batteries sitting in the rack so I could use them for phones in an emergency. That would be a dilemma. What is more important, vaping or phone.
