Powering 55x WS2812B using PC/Laptop usb port?

[advanced03]

Hey guys I have a question. I have 55 leds of ws2812b, and a esp sharing a common ground.

My question is if it's possible for my laptop's usb port to power the strip? (Esp being powered by a separate port)

I've tried it for a minute and it seemed to work fine, even in high brightness situations

But i want your opinion if this is safe?

Or am I better off using a seperate power supply for the led strip?

Hi
36mA * 55 = 1980 mA = ~ 2A well beyond 0.5A (USB2.0) and 1A (USB3.0) standard. But may work or not out of any standard depending how strong is your USB power source internal converter is.

This is the worst case scenario. If you have a multi-meter you can measure actual current when displaying full white color (for sk6812 is more complicated).
