In this video, we will walk through using a Refurbished Pure Sine Wave inverter. Refurbished means that the piece failed the quality checks at the factory and was reworked to correct the error in the original workmanship. The factory asserts that the refurbished equipment is in near-perfect condition. Refurbished equipment is generally sold at a discount.

Medical equipment, such as a CPAP machine, often requires a pure sine wave inverter in order to operate on battery power. The video will walk the viewer through the process of connecting a pure sine wave inverter to a Harbor Freight 35 AH battery, connecting the pure sine wave to a standard CPAP machine, and testing the system.
