micro converter power consumption

PostSat Nov 14, 2020 9:07 am

Hello.
I found this about micro converter hdmi-sdi and sdi-hdmi:

Power Consumption - 2.0 Watts (hdmi-sdi)
Power Consumption - 1.60 Watts (sdi-hdmi)

I am looking for a USB-powerbank to power them.

Maybe a 2000 mAh 1A output works?
For how long (1 hour? 2 hours? 3 hours?)

Thank you

Tiago

You can calculate this with very simple math:

USB is 5V. 2W @ 5V = current draw of 400mA.

2000mAh means 2000 mA for an hour. 2000mAh / 400mA = 5h. Take away some to compensate for efficiency, and you'll get somewhere between 4 and 5 hours out of that powerbank.
