EcoFlow NextGen 220W Bifacial Portable Solar Panel pairs a 220W front side with a 175W rear side, and EcoFlow lists 25% efficiency on the U.S. page. The same page shows IP68 protection and a 12-month U.S. warranty, while Best Buy lists the panel at $299.00 as of 08/14/2026.

Specs And Box Contents

The U.S. product page names the model as EcoFlow NextGen 220W Bifacial Portable Solar Panel and lists Rated Power at 220W (±5W) Front/175W Rear, Efficiency at 25.00%, and Weight at Approx. 15.4 lb (7.0 kg). Its Specs section also gives Unfolded Dimensions of 24.2×84.8×1.0 in and Folded Dimensions of 24.2×23.2×1.3 in.

The same page includes the box contents: EcoFlow NextGen 220W Portable Solar Panel, XT60i Charging Cable, Protective Bag, Quick Start Guide, Safety Instructions, and Warranty Card. It also lists Connector Type as Photovoltaic connectors, Open Circuit Voltage as 21.5V, and Short Circuit Current as 12.4A front side and 9.9A rear side.

Price And Warranty

Best Buy lists the EcoFlow NextGen 220W Bifacial Portable Solar Panel at $299.00, and the retailer says the solar panel has a one-year warranty for parts and labor. EcoFlow's U.S. page shows a $399.00 regular price, so the retailer price sits below the brand's listed amount.

EcoFlow's manual page adds the exact model code EF-Fold-P220-04, confirms the Solar to XT60i charging cable at 2.5 m in the box, and repeats the IP68 rating. The manual also lists the recommended ambient temperature as -20°C to 85°C (-4°F to 185°F).

Where It Fits

EcoFlow's U.S. product page describes the panel as compact, foldable, and 10% smaller than comparable 220W panels. That puts it in the portable solar panel class, aimed at portable power stations, RV use, and off-grid charging.

Outdoor Gear Lab's review of the NextGen 220W says it generated 193 watts over an hour in its head-to-head efficiency test, which is lower than the panel's 220W rating but still led the publication's portable solar lineup. That gap matters when the goal is to compare rated output with real-world testing.

Verdict For Buyers

The EcoFlow NextGen 220W Bifacial Portable Solar Panel is a bifacial folding panel with a 220W front side, 175W rear side, 25% efficiency, and IP68 protection. It is a straightforward fit for users who want a portable panel with a documented cable package and a 12-month U.S. warranty.

Its strongest case is compatibility with EcoFlow power stations and other systems that accept photovoltaic connectors, while the 15.4 lb weight and folded size of 24.2×23.2×1.3 in shape how it travels and stores. For readers comparing portable solar panels, the key tradeoff is the premium for bifacial design against the lower street price reported by Best Buy.
