EcoFlow’s 220 W panel uses N‑type cells rated at up to 25% efficiency and collects light on both sides, which EcoFlow says adds up to 28% more energy over reflective ground. It weighs 15.4 lb in its current version and folds into a case that doubles as a stand with a 30–60° adjustable angle and a sun‑angle guide.
Mighty Gadget hit the full 220 W peak on both a RIVER 2 MAX and a DELTA 2. Its low 21.8 V open‑circuit voltage suits almost any power station, including small units with limited input voltage, and two of them can be wired in series for stations with higher voltage ranges.
Pros
- Reached its full 220 W rating in tests
- Bifacial N‑type cells, up to 25% efficiency
- IP68 and ETFE coating
- Low voltage works with almost any station
Cons
- The bag‑stand takes practice to set up
- No USB ports for direct charging
- Non‑EcoFlow stations may need an MC4 adapter
Who it’s for
- Pairing with any 1–2 kWh power station
- Camping on sand, snow or light ground where bifacial gains are real
- Buyers who want one panel that does it all

Estimated at 70% of rated power to account for clouds, angle and heat. Stations marked * accept less solar power than the panel can give, so they cap the speed.
Before you buy: check that the panel’s connector fits your station (or buy the adapter) and that its open‑circuit voltage (Voc) is within the station’s solar input range. Panels can be wired in series or parallel to add power if the station allows it.
What reviewers and owners say
Mighty Gadget found it outperformed one‑sided panels at no extra cost and was far easier to handle than EcoFlow’s 400 W panel, with the stand‑bag the only real annoyance. On Amazon it averages 4.5 out of 5 across more than 700 ratings.
