Planning figures: a typical refrigerator averages about 83 W; an older furnace blower averages about 182 W. Yours may use less or more; the range is in the table below. How long other power stations run a refrigerator. A furnace blower is wired in: it needs an inlet or transfer switch fitted by an electrician.

The range behind that

This is a 6,438Wh battery with 3,800W of output, which means it gives back about 4,553 watt-hours at a typical household load (estimated) and can run anything drawing up to 3,800 watts at once.

It runs indoors and makes no fumes. Of the 16 household loads we track, it can run 16 for at least part of a day. It would keep a refrigerator going for 28–45 hours, from a hard-working fridge to an efficient one.

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.

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.
