The term refers to a portable, self-contained source of electrical energy sold at a major home improvement retailer. These units typically incorporate a rechargeable battery, outlets for standard AC power, and often USB ports for charging smaller electronic devices. A typical application involves providing temporary power during outages or at locations lacking readily available electrical access, such as campsites or remote work sites.
Such a device offers substantial advantages, including enhanced mobility and convenience in accessing electrical power. This utility translates to increased efficiency and productivity across diverse activities, from powering tools at construction sites to ensuring continued operation of essential equipment during unforeseen power interruptions. Historically, the need for such portable power solutions has grown in tandem with the proliferation of electronic devices and the increasing demand for uninterrupted access to electricity in various settings.
