DIY,

I bought a GSTORY monitor. The goal was to use my BatPower battery to run it while on a long flight. When I hook it up I made sure to match outputs and polarity (12v 5a). The screen just flickers. Any suggestions?

Try a FagPower instead.
Probably it can't draw 5A from that piece of shit battery.
Also some transformers (what you liberal cunts call power bricks) are made not to work only with approved devices. Once I had a US Robotics modem and there was fucking literal DRM on the 9V power supply. They were doing something with pulse modulation or whatever the fuck so the modem only accepts their transformer,

Try another source if 12V power, say a laptop power supply and check whether it also works.

Using a meter I get a pretty consistent 5a off the battery. I bought it off ebay with a generic power supply and it works fine with that.

Sometimes ot doesnt flicker so maybe it's a cable.

Prolly it's flickering because the battery BMS board is dick. Maybe you need a capacitor in between the power bank and the display.
Again - by process of elimination you can tell what the problem is. If you use another power source and it's still happening etc.

Does the battery actually put out 12 V? Often those banks just have cells straight across the output, so you can have anything from 15 V down to 9 V there.
