I just purchased an "inverter". Specifically, a Motomaster Nautilus 450W Power Inverter.
The instructions include the following caution : Output non-sinusoidal. Do not use with following equipment:
-small battery operated products such as rechargeable flashlights, some rechargeable shavers, and night lights that are plugged directly into an ac receptacle to charge.
-certain battery charges for battery packs with power tools. These chargers will have warning labels stating that dangerous voltages are present at the chargers battery terminals.
Primarily I wish to know if this invertor can be used to charge my 14.4V batteries for my mastercraft drill. I have the 1 hour charger. The charger does not have the warning mentioned above printed on it, but I no longer have the instructions that came with it. The charger is quite heavy and therefore I assume it contains transformer, rectifier, etc..
I'd also like to know what it is about the power supply design of some equipment that makes it incompatible with a non-sinusoidal power source.
Thanks, Russell Wardman
