Key Takeaways

Best for: EcoFlow station owners who want a fast, light folding panel
Standout: measured 193W in independent testing, at about 15.4 lb
Watch out: only a 12-month US warranty
Not for: tight budgets, or anyone who wants a panel mounted outdoors for good

The EcoFlow NextGen 220W is a folding, two-sided solar panel for recharging a portable power station during outages or trips. It sells for about $399 at EcoFlow and major retailers, with prices up to $449.

Want to see how much a panel would refill your battery during an outage? Our Whole-Home Energy Calculator lets you pick a panel and a power station, then shows the daily refill, how long your essentials would run and which cable the pair needs.

What it can power

In 4 to 5 hours of good sun, expect roughly 660 to 825Wh a day from the front side alone (estimate: 220W x 4-5 sun hours x 0.75). Over light concrete or sand, the rear side can add a bit more. One panel can refill most of a 1kWh station on a sunny day. In winter or under clouds, plan on half that or less, and angle the panel toward the sun rather than laying it flat.

Compatibility

EcoFlow DELTA and RIVER stations: the included cable ends in an XT60i plug.
Other brands: the panel’s own leads are standard MC4, so any MC4 cable works.
Jackery HomePower and newer Explorers: need an MC4-to-DC8020 adapter.
Two in series: about 43V open-circuit, which fits 60V inputs.

Pros

Measured 193W, the top result in OutdoorGearLab's portable panel test
Best watts per pound in this group, at 220W and about 15.4 lb
Included XT60i cable plugs straight into EcoFlow stations
IP68 rated, with a 30-60 degree kickstand and sun-angle guide
Rear side rated up to 175W over reflective ground

Cons

12-month US warranty, the shortest among the name brands here
Rear-side gain shrinks to about 5-8% over grass (Off Grid Benchmark)
No cover on the solar connectors (OutdoorGearLab)
Jackery HomePower units need an MC4-to-DC8020 adapter

Specs

Rated power	220W front / 175W rear
Open-circuit voltage (Voc)	21.5V
Max-power voltage (Vmp)	18.4V
Max-power current (Imp)	11.9A (front)
Short-circuit current (Isc)	12.4A (front)
Cells	N-type TOPCon monocrystalline, up to 25% efficiency

Verdict

The strongest all-round folding panel here: light for its output, weatherproof and plug-and-play with EcoFlow stations. If you want the lowest cost per watt or a longer warranty, pick the ALLPOWERS SE200 or a Jackery bought direct.

Common Questions

Should I buy the carrying case?: It helps. OutdoorGearLab found the panel much harder to carry without it, and the case adds only about a pound.
How high should I raise it to get rear-side power?: Use the kickstand and set it over a light surface such as a patio or driveway. Laid flat on dark ground, the back side adds almost nothing.
Can I mix it with a different panel?: It works best with panels of similar voltage and current. Mixing very different panels in series limits the pair to the weaker panel's current.
