What to know before buying
Listing details to confirm
The listing describes this as vehicle-powered, while its specification table says “Battery Powered.” The title and feature claims refer to 12V/24V use, but the minimum-voltage field is malformed, so confirm the selected version’s supported supply before purchase. It also claims a 20-foot cable and a 4.96-inch compact size without clarifying whether the latter is the tool’s overall dimension. The technical details list only general compatibility, while the feature claims mention battery clamps and a cigarette lighter adapter. Confirm the exact cable length and package contents for the selected listing.
