Hi

In my little world, the plan is to use a 500W modified sine wave inverter to power a couple chargers that I can't seem to find the 12V equivalent for.

One would be a regular 110V Ryobi charger and the other a 110V charger for 9 Volt Ni-MH batteries.

After getting this stuff together I read that using an transformer with a inverter is bad. What would happen? Would I fry something?

Any insight would be appreciated

TIA

Bob
