I was wondering is there a way to power any orange pi model so that it could be completely portable like those battery chargers. I see for phones would they be safe to use and would they provide enought power if any ideas please let me know as. I want to learn coding and programming while of lunch breaks at my current job at walmart

It would have to be a quality USB battery pack. (One that provides the 2.1 amps). What kind of screen would you use? Orange pis are great, but known to be a bit difficult to get working with screens that are not HDMI or AV

Yes, as example if you use a LiPO battery pack and a battery controller board, you can use 3 cells to power a DC-DC converter, as example with 3 Amp capability and supply 5V to OPI board, the battery controller will take care for the battery pack to be charged / discharged and protected from overcharge and undercharge. The setup is not exactly minimalist but it may be used to create a laptop substitute.
I have used a 12V 2A netz adapter to power a DC-DC converter LM2596 which step down the voltage to 5.1V and can drive up to 3A. The output from the DC-DC is soldered to the OPI PC board with short wires. There is an additional 1000 uF cap at the 5V line. The setup works great, so I made the same for my raspberry pi board, now both are hard wired. I don't need to think about connectors.

If this all mean nothing to you then probably you can start with something else if you are still interested just drop a message and I will send more data and some links.

I am interested in learning this circuit. If you can load energy and keep the system running ... it would be amazing.
I saw on a forum that can be loaded this card ... by GPIO port.
Tell me if you are running this system power supply and if you have photos or something. It would also be good to know the plane of the circuit
Thank you very much
