Pure Sine Wave
Pure sine wave inverters produce the equivalent to utility-grade power, and today there are several models that can do this at a low cost as well, even delivering up to 2000 watts (4000 watts in Surge). This power source will help your tools and equipment run more efficiently, preventing failures due to excessive heat. Cordless tool chargers will not damage expensive batteries. Many devices like variable speed motors, communications equipment, and many cordless tools require pure sine power to operate.
