hi,
I am trying to power a 5v USB thermal printer via a power bank (Xiaomi to be specific). Funnily
I tried two power banks and some AC-DC adapters but they did not work.
However, i have one particular adapter that works and so does as Lead Acid battery.
All adapters/banks show 5v although I probably have not tested under load.
The current drawn varies and has a max of 1.5a which all power sources support.
i would really like to run off the power bank since it makes it portable.Is there something to the technology used? can some tweaks make these banks power the printer?
TIA,
