Hi, apologies if this is a bit basic but I am trying to power a LCD screen using a portable power bank and would like to know what size battery I need to power if for 6 hours.
The screen runs at 130mA at 12V apparently, so 1,560 mW.
This equates to 1.56 Wh
So, 1.56Wh x 12V/1000 = 130 mAh per hour
=> 130 * 6 = 780 mAh
These calculations don't seem right but not sure where I am going wrong. Can any help please?
Thanks!
Alex
