I had an interesting conversation with one of Outside Supply's power inverter vendors regarding charging power tools on modified sine wave power inverters. You can actually significantly impact the life expectancy of your power tools battery by charging on a modified sine wave power inverter.
We suggest getting a large modified sine wave inverter for those heavy duty jobs that don't require Pure Sine Wave.
Then Outside Supply can also get you a 300 or 600 watt Pure Sine Wave Power inverter to use when charging your power tools. These Pure Sine Wave inverters produce power identical to that of the AC Power Grid, actually it can actually be cleaner and better power.
This way you get the best bang for your buck. However you do have two inverters to use, so you might consider 1 large pure sine wave like our 3000 watt Pure Sine Wave Inverter.
