Single Power Supply OK for 2 Chargers ?
I presently have an Astro-Flight 12.5 Amp power supply (Model 120) and an Astro Flight Lipo charger. Can this single power supply be utilized simultaneously by 2 chargers ? I would like to by another charger so that I could charge 2 batteries at once.
Thanks. Bob

If you don't know the wattage of the chargers you are trying to "drive" with one power supply here's the formula for figuring it out. Wattage = Current * voltage. So, say you have two chargers that each require 12 to 13 volts input and draw a maximum of 5 ams each. The total wattage required to "drive" the two charges is, 130 watts or 2 * 5 amps * 13 volts (always pick the highest voltage to be safe).

Understand that this figure is a "max" figure for the two chargers. If they are doing a small job then the power figure goes way down and is directly related to the specific job that the charger is oing at the time.
An example might be a single ps powering a single charger at max power vs. a dozen of the same chargers doing radio batteries.
