Goal Zero Yeti PRO 4000 review
Goal Zero Yeti PRO 4000 Portable Power Station (3,994Wh)
By Tom Calder
Goal Zero's own page lists 3,994 Wh, 3,600 W continuous and 7,200 W surge, with a 5-year warranty. It says the unit can back up to 10 home circuits through its Haven 10 manual transfer switch and runs almost any home appliance aside from air conditioning. A good fit for fridge, lights, Wi-Fi and a medical device, and it needs a transfer switch or an electrician for the circuit hookup.
- Best for
- A US household that wants a plug-in battery that can also feed essential circuits through a transfer switch
- Skip it if
- You need central air conditioning to run in an outage
