My 2 cents comments :

1st, led needs constant current driven, driving it using constant voltage is not good for the led's life.
2nd, dissipating the led's heat straight at the power bank body with no thermal cut off or monitoring which contains the Li-Ion cells is not good for ... your life.


Oh , last one, putting a spam at your sig also is annoying.

Hi BravoV

Thanks for those good points! Noted the sig and reduced the estate. LEDs with internal resistance doesn't require current-driven power source. Also, a newer version is being worked on with additional features after our demos.
