Chris,
If this charger only puts out 12V, it's not going to be a very effective charger... ;)
12V chargers typically operate at voltages up to 14.5-15V (less for gel batteries) so I use 15V for estimating. Add in the fact that the best electronic chargers are just above 90% efficient, transformer based chargers are often around 80%, then the current draw at 120V will be between 500W and 550W (4.1A to 4.6A) for each charger. Since the Honda and Yamaha 2000 chargers are rated for only 13.3A (1600W)continuous, you would only be able to run 3 chargers at a time.
Fair winds,
Eric
