5v WS2812 5m led strip from battery?? :(
<< < (5/5)

Its all weird, tried connecting with out dc-dc, and USB doctor now says 3,2 amps. And when lots of white light shine, whole system shuts down.
But when its connected through dc-dc, USB doctor says 2.3-2.7 amps, and no problem with white at all...

Could be that dc-dc adds some pwm??
frozenfrogz:
USB connectors are available with a maximum rating of up to 3 A, though most common grade ones are 1 - 1.5 A max.

My bet is, that the maximum current allowed per outlet on your power bank is around 2 A.

You are lucky, that the power bank seems to have some kind of emergency shut down in place, otherwise you and your contraption might already have ended up in fire and smoke.

The led controller run animations on led strip so 2.7 its max peak when lots of whites shine, but average is about 1.7-2.0.
Im testing it now and it already 2.5 hours on. Usb port is warm but not hot.
So hopefully it will work)
