An electrically driven pump feeds fuel through a default 0.072 in solid-stream nozzle, while twin ceramic arc-ignition electrodes and a perforated drip shield support consistent ignition and controlled emission. The onboard reservoir holds 0.25 gal for roughly 20 seconds of runtime, with a typical reach of at least 25 ft.
The system runs on a 2200 mAh 3-cell rechargeable lithium battery with an integrated voltmeter and low-voltage cutoff. This setup helps manage power use and simplifies status checks before operation.
Construction centers on aluminum and brass with Viton seals and a black powder-coat finish. At 16.0 x 5.0 x 9.0 in and 6.0 lb empty, it maintains a compact footprint. Introduced in 2022, it is compatible with unleaded gasoline or gasoline/diesel mixes up to 50% diesel, and an optional backpack kit can extend runtime beyond 4 minutes.
