Question

If you run two 12v dc chargers in series can you come up with a 24v dc charger?

Answer 1

I've connect chargers and power supplies in series lots of times in my line of work.  There's no real problem in doing so.  Just remember that the amps will be limited to what the lowest rated supply can put out.  This is also a way to get a negative and positive voltage if you need if you connect the common set of leads to ground.  You do have to be careful when you do this and know that the chargers aren't grounded on their negative lead.

Answer 2

Actually the other answerer is wrong.  Voltages add when in series.  Two 12 volt batteries in series would produce 24 volts.

The problem is that you probably should be careful when connecting two chargers in series.  They may not be designed to do that.  You may blow one or both of the fuses in the chargers if you try that.  On the other hand it may just work.

Answer 3

No, running chargers in series only boosts the wattage.  The voltage is controlled by the lowest in the series.

6V + 12V = 6V

12V + 9V = 9V

Make sense?  In order to get 24V DC your converter/inverter has to be 24V.

Hope that helps.
