The short answer
Jackery is the easier default: it's sold directly on Amazon with fast shipping and easy returns, has a wider range of battery sizes (288Wh to 2,000Wh+), and its SolarSaga panels are purpose-built and widely reviewed. EcoFlow pulls ahead on warranty length (5 years vs. Jackery's 3) and offers hybrid units — like the STREAM Ultra — that combine a microinverter with a battery, useful if you also have a legal plug-in solar setup and want daytime storage in addition to backup power. For most people buying their first solar generator, Jackery is the simpler choice; buy EcoFlow if the warranty or hybrid microinverter option matters to you.

Both work the same way
Regardless of brand, these are standalone battery power stations — the panel charges the battery, and you plug devices into the unit's own outlets. Neither connects to your home's wiring, so both are legal to use in every state, including ones without a plug-in solar law yet.
