How long will the Yeti PRO 4000 run a fridge?

A typical full-size fridge draws roughly 1 to 2 kWh a day, so the 3,994 Wh battery can carry one for about two days before recharging. Heavier loads like a well pump or space heater drain it much faster.

Can it back up a whole house?

It can power selected circuits through a transfer switch, not an entire home at once. At 3,600 W continuous it handles a fridge, lights, router and a few small appliances together, but not central AC or an electric range.

How fast does it recharge?

With the 1,800 W AC wall charger it reaches full in about 3 hours. Solar charging tops out at 3,000 W using Yeti PRO high-voltage panels.

Can I use my own solar panels?

Only with limits. The high-voltage solar input uses Goal Zero's proprietary connectors, so third-party panels need adapters and will charge more slowly than the rated 3,000 W.

How long does the battery last?

Goal Zero rates it at 4,000 cycles to 80% of original capacity under climate-controlled, 0.5C discharge conditions. That is roughly a decade of daily use.

How many outlets does it have?

It has five AC outlets plus USB and 12 V ports. That is enough for most backup setups but fewer AC outlets than some competing stations of similar size.
