T&T: 24V backup charger...

[Jeffrey Siegel]

One of the single-point failure potentials on my boat is the 24 volt  
charger for the bow thruster bank.  I have a single charger with no  
backup.

True to form, the charger stopped working.  I just pulled it out and  
can't find anything serviceable (fuse, breaker, etc).  Hopefully it  
can be fixed.  I can't understand why a replacement costs over $1,000.

Anyway, it got me wondering about a backup 24 volt charger and a way  
for me to charge my bow thruster bank right now.  Here's my question...

I have a couple of those cheap 12 volt car chargers.  You know them -  
they're the type that have two big clips on the leads and are used to  
charge and/or jump a car.  Could two of those be put in series  
(connect red from one to black of the other) to get a basic backup 24  
volt charger?  OK, I know it will output 24 volts for charging but is  
it safe to do that for a few hours?
