For those of you considering options for a solar panel, I just wanted to share my experience with both the original version of the EcoFlow 220W Bifacial Portable Solar Panel and the EcoFlow NextGen 220W Bifacial Portable Solar Panel. I would say that both are effective for charging up my power stations. I like that I can use them with my smaller power stations, such as the EcoFlow RIVER 2, RIVER 3, RIVER 3 Plus or RIVER 2 Pro, as well as with my larger power stations, such as the EcoFlow DELTA 2, DELTA 3 Plus or DELTA 2 Max. I dont have larger power stations than these ones listed, but both versions of the solar panel can be used with the larger power stations as well. This makes them very convenient for me, since they are compatible with all of my devices. -Anyone thinking to upgrade from the original version to the EcoFlow NextGen 220W Bifacial Portable Solar Panel would be happy to know that the NextGen version is easier to handle, less wide when folded up, so it takes up a little less space in the vehicle, easier to set up due to the built in kickstand, easier to properly angle due to the built in solar angle, and 5.5 lbs lighter. The upgrades make life alot easier for me, especially while setting it up on my own.
