Enerco Group Inc.’s DeWalt DXH70CFAV cordless portable propane heater operates on LP gas and any size DeWalt 20V Max or FlexVolt battery system. According to the company, battery-powered operation eliminates that need for a power outlet, making the DXH70CFAV ideal for job site or emergency power outage outdoor use. The DXH70CFAV comes equipped with Quiet Burner Technology, which allows it to operate about 50 percent more quietly than standard forced air LP heaters, the company adds. The DXH70CFAV also features a heavy gauge steel, split-barrel design, recessed control knobs and an ergonomically optimized handle. The LP hose and regulator come standard with the heater.
