I am attempting to test a Non-Isolated 12V Orion DC-DC Charger before setting it up in the back of my car for a campervan setup. I am wondering if I can connect the input of the Orion to a DC charger that connects to a 120V wall plug directly, instead of connecting it to my alternator or an external battery. I've used the wall plug DC charger to charge the battery LiFePo4 I am planning to install. Thanks!
No.
It is a DC to DC charger - wall plug is AC. And input of the AC voltage is out of range anyway. (Answer based on the statement can i plug it into AC)
You mention a charger? Can it supply the amps of the Orion, remember there is no current limiting it may trip. Can't be more specific without knowing what you have exactly.
I don't know exactly what model you have so can't link the datasheet, but the 12v ones are usually 7-17v DC input.
It will only work if the wall plug charger can supply enough current to the Orion, as @Alexandra said, without tripping.
