The Chargers' main job seems to be the manufacture of Blaze through the conversion of grass, similar to Striders, Grazers, and Broadheads. They are often seen in herds.

While it's unknown when Chargers were first released, they became one of the widest spread of all the machines, being commonplace in the Valleymeet, the southern half of the Sundom and the Daunt, along the northern border of the Sundom, the Cut, and across the entire Forbidden West, especially the northern half. The only known place with no Chargers is the Burning Shores.
