Power Bank help please

Post by wobblybootie » 10 Mar 2018, 14:38

Due to unfortunate circumstances I find myself the owner of a power-bank that can be used to jump a car and provide 5v for phone charging. I am wondering if the 12v output could be put to a different use ie powering a NV set up. I know very little about the electrics in these things and am also lacking in testing kit for a while.

If I were to connect a 12v device (screen) to the output of said bank would it dump the full power into the screen OR would the screen only draw what it needs. Furthermore, I have no idea if the circuitry of the lump would accept a slow current draw.

The lump in question is a FlyHi D12 18000mAh (start current 400A Peak 800A) I know I could just plug the screen in but it's a lovely 7" HDMI / AV unit (and it belongs to SWMBO)

Any suggestions??

The screen will only draw the current it needs to work. You can safely connect to the 12 volt output of your power bank.
