ok so, wtp, has given me a new perspective with his comment above. Here is where i'm at in my reflection..
1. QDP2012, has explained that I will need a 'buffer' between both chargers. Well, there is a buffer between the two in the form of capacitors, Actually, there are two buffers, as each chargers give out the final DC power trough those.
2. I'm not clear on how both chargers will 'balance' themselves out, as they both do the same thing at the same time.
..
1. No. Please re-read the earlier posts. With the two-charger design, you need an
isolator between the chargers. A battery could go between the charging-system and the device...maybe...if the device's design allows that option.
2. Forget the idea of chargers that "balance" themselves or that "work together". When properly isolated, they don't know each other exist. If they know each other exist, they "fight", and one (or both) of them will lose the fight.
2b. When you study the theory and learn about what is happening inside the chargers, you will learn that they will never exactly "both do the same thing at the same time", even though each charger's "purpose" is the same. Please re-read the earlier posts about "out-of-phase" and about voltage-differences.
Until you have an opportunity to properly learn circuit-theory, this same knowledge-gap will seem to go against your intuition. Unfortunately, this is one of those times in life when the "simple-theory" intuition is incorrect. Take the time to learn the rest of the theory. Until then, hopefully, you will not risk your equipment with the non-isolated two-charger experiment.
Either get an isolator, or get a better single-charger.
Hope this helps,
