I give up. What don't you understand in this sentence: "If you restrict the charging voltage to 5 V, however, no harm should be done."
my smartphone charger device operates 100-240V 50 / 60hz 0.3A DC 5.0V = 3.1A Max is this charger harmful to the life of the 18650 lithium battery used in the plasma pen?

Hello,

It depends on how "smart" the charger circuit in the pen is.
As you did not provide any information, we can not give you the information if it is safe for the pen.

If I don't know the pen's internal charging circuit then I better not risk losing the default device caused by using a smartphone charger, thanks for help
