That "jacked up customs" one looks like a converted computer PS with blingy lights and fans. For the price, you could get a 12v specific PS, and usually those have internal trim pots to adjust to a higher voltage (like around 14v). Higher voltage (14v vs 12v) will make the charger pull less current for the same power requirement.

And yeah, the total output is still 20A no matter how many physical connections there are. As long as the sum is 20A, one connection could be pulling 15A and the other 5A and that's fine.

Yep. I think they have very little "design" input to that PS conversion.

What gets me is this comment:

In some cases we have found that some people required a power supply to run off of a Car DC to AC converter. The PP620 has been designed and tested to work with most Car Power Converters if you have such a need.
So let me get this straight: these people are going from 12vdc from the car, through an inverter to make 120vac to run the PSU to make 12vdc. I would love to know what those "some cases" are. Maybe cases of extreme brain dysfunction? I think "jackedupcustoms" refers to them jacking you up more than anything else!

Brian, I think I'm going to go try and hunt down those trim pots in the PS. Would be nice to keep it at 12v or higher. I'll try not to become part of the circuit in the process. Edison said that DC is safe, but I still have no desire to be bit by it!

10 4 on the wiring to the charger. When I got it, I thought the wiring was really huge, but apparently it's not quite big enough. The only time it gets warm is when i charge that big 5S pack (~21v at 8A is quite the workout!). I know it's not tiny gauge stuff, it looks like it's better than 16Ga. I think part of the problem is that they used so darn much of it! 2' would have been fine. I've never even unclipped the cable tie holding the bundle together.
