So here's the deal, I need mobile power for an LED display with no power nearby. I don't know electricity for shit, but have googled and did some research and just need somebody to check my math basically.
So I found a 12,000mAh Power Bank that has an AC Outlet and can continuously power up to 65 Watts max (more than enough).
The LED modules I'm ordering pull 38mA or 0.45W MAX, I need 12. I need to know how many hours the power bank will run the lights for. By my math, all 12 modules will be pulling 456ma or 5.4W. So a 12,000mAh power bank SHOULD power them for just over 21 hours, assuming a 20% loss. How far off is my math?
