What to know before buying

Listing details to confirm

Runtime is contradictory: the specifications list 40 hours, while feature text claims up to 48 hours. The listing also gives conflicting electrical details, listing 120 volts and 20 watts in specifications but describing 24V low-voltage operation in feature text. Check the selected listing and instructions for the applicable runtime and power configuration before use. The title's 8L capacity and feature text's 8L (2.1-gallon) description are not exact conversions.

Aggregate ratings lean positive, with most ratings in the five-star category and the remainder in the four-star category. No written customer feedback is supplied, so these ratings do not establish specific strengths or concerns. They offer limited guidance for buyers weighing the claimed 8L capacity and adjustable controls against the unresolved runtime and electrical details.
