What to know before buying

Listing details to confirm

The listing is inconsistent about output: the title and output field say 2400W, while other details claim 3400W through X-Boost and separately list 3400 watts for running and starting, the 2048Wh LFP capacity appears in the title but not the technical details. Treat these as listing claims, not a settled continuous-output specification, and confirm the intended operating limits. The 0–80% time is given as both “1.13 Hr” and “just over an hour.” No solar panel is specified in the package contents, and the highlight calls it optional, confirm the selected bundle if solar charging is needed.
