I want to be able to charge my saw battery from my truck battery inverter, and dont know if it is okay to do that.

I used to use a small (400w) inverter to charge my DeWalt & Craftsman batteries all the time. This worked fine. I'm no longer in that line of work so I don't need to. Just check on the bottom of the charger to figure out how many watts it's going to pull. If it's listed as amps, multiply the amps by the voltage (115) to get the watts.

You didnt tell us how many watts the charger needs, or how many can be supplied by your inverter... thats why youre getting the math lessons, hehehe
BOTH items should have a 'data plate' on them, specifying what they need/use. As long as the inverter can supply more than the charger will require, youre fine. The inverter will also list a 'peak' wattage....this is how much it will allow for just a few seconds use, like when starting an electric motor, important to know when youre running a refrigerator, or compressor, for example. It is not intended to run at "peak" over an extended length of time, but I doubt very seriously that your charger will take that much draw.
I used to charge all my batteries while traveling like this.
Have Fun

Determine the charger's wattage using the
Basic Power Formula: P= V x I (use the manufacture information off the drill)
P is the power in watts
V is the potential difference in volts
I is the current in amperes
The basic power formula is used to calculate the electrical power P dissipated in a resistor or a circuit, given the voltage V across it and the current I flowing in it. The voltage drop across a resistor is also referred to as the potential difference.
If the wattage of the chargerl does NOT exceed the listed(NOTE:Not Peak-will blow the fuse) wattage, the charger is compatible. If it exceeds the listed wattage, you will damage the inverter and/or the charger.

Depends how many watts that the charger demands. The easy way to find out, hook it up and try it. It will just shut off if the demand is too high. My 2000 watt inverter does work on my 18vdc Black and Decker. Good luck.
