Topic: Powering a 18W LED [Kind of Emergency] (Read 128 times) previous topic - next topic


Hello Everyone,
For my sister's birthday, I am making a voice-commanded W2812b LED strip. On the site that I bought the LED strip, it is claimed that it should require 18 watt. As it is voice commanded, the system will be on all day (even though LED strip will be turned off for the majority of the time, bluetooth will be on so that my sister can use the voice command without doing an extra thing). With this information, in what way should I power the system? Batteries will suffice?

Thanks in advance for your quick replies. Her birthday is tomorrow and lazy me haven't done with the project yet!



18 / 5 is 3.6 Amps so look for a 5V power supply rated for at least 4 Amps.
