If you need to run a fridge, AC, or power tools — go DELTA. If your priority is weight and price for outdoor trips — go RIVER. Our RIVER 3 vs DELTA 3 comparison breaks down the exact trade-offs, or jump straight to the Best EcoFlow Power Stations 2026 ranking to see every model scored and ranked.
Every EcoFlow charges from the sun
Whether you own a RIVER 3 or a DELTA Pro Ultra, solar charging works out of the box. The real question is which panel to pair and how fast you'll charge. EcoFlow panels range from 45W ($79) to 400W ($599) — and the NextGen 220W Bifacial captures light from both sides for faster results in mixed conditions.
