Advise Needed For Running Led Lights From A Powerbank

Nov 23, 2020 LEDs should be supplied with a current, not a voltage. So if you have a 1W LED that takes 312 mA at 3.2 V, you should supply it with a maximum of 312 mA. The exact voltage across will be near 3.2 V, but may be a bit more or a bit less. You can supply it with less current. Anywhere down to 110th or 120th will be fine.Nov 23, 2020 LEDs should be supplied with a current, not a voltage.
