Square wave or sine wave inverter?
Has anyone had problems using a square-wave inverter to charge laptop batteries?
I know not to run things with motors on square waves inverters, but I thought square waves were fine for batteries until I fried the battery pack for my DeWalt drill. Now I'm gunshy of charging the laptops (a Compaq and a Gateway). Thoughts, please?
