Can I connect 4 LED strips to 9V cell phone power supply ? Answered
I don't know specifications of the LED strips all I know is that they are 12V, 30 cm long, supposed to be waterproof and they are blue light.
I've connected 4 LEDs in parallel to a 9V cell phone power supply with 200mA output...when i plug this whole assembly in it works - they all light up...how log will they last? From what i've read it seems to me that my power supply might not have enough wattage. Is the power supply going to die because not enough wattage or something will happen to the LEDs?
