The range behind that
This is a 448Wh battery with 700W of output, which means it gives back about 385 watt-hours at a typical household load (estimated) and can run anything drawing up to 700 watts at once.
It runs indoors and makes no fumes. Of the 16 household loads we track, it can run 9 for at least part of a day.

Hours of use on one charge. Typical is the middle of our range for that appliance; the range runs from a hard-working unit to an efficient one. Short-burst loads (microwave, coffee maker, garage door) show running time at full power instead. “Starts it” means the peak output covers even a hard-starting one.
Specifications
Recall screen
No published recall names this exact model
No CPSC recall in the 2026-10-09 recall list names this exact model. No recall in the recall list we checked names this brand at all, so finding nothing here says less.
This check cannot clear your own unit. Most recalls cover only certain serial numbers. Read the model and serial number off the label on the unit itself, then check the maker's recall page before you use it, sell it, or buy it.
Use the CPSC recall search.
How we know the screen was not simply blind
Finding nothing only means something if the search could have found something. So we searched the same records for this brand and got 0 recalls. No recall in the recall list we checked names this brand at all, so finding nothing here says less than it would for a brand that does appear.
