I am attempting a DIY hack that involves (among other tweaks) replacing a battery pack with a PoE power supply. The battery pack in question uses 8 1.5v D-cells in a series-parallel configuration that produces 6v.
How do I go about figuring out how many amps my power supply will need to support? The device in question is an LED lantern, and the only likely-looking spec I can find is the marketing claim that 8 alkaline D-cells will last 32 hours on the high setting.
Also, am I correct in my vague understanding that amperage is generally a capacity, and thus more amperage is generally not harmful? Whereas too little amperage will result in a voltage drop? (I did study basic electronics in the military, but that was a very long time ago…)
