The EcoFlow 400W Foldable Solar Panel is a single-piece module with a 23% efficiency rating, made to charge portable power stations in a hurry. Folded it measures 60 x 105.8 x 2.5 cm, unfolds to 236.5 x 105.8 x 2.5 cm and weighs 19 kg, so it stays realistic to lift and store in a car boot. The mix of pliable EVA and glass-fibre composites keeps each monocrystalline cell protected by ETFE film, delivering the flexibility of a foldable design with the robustness of a rigid panel. IP68 rating means dirt, dust and low-pressure water jets are not an issue.

• 400 W max output (±5 W) with 23% panel efficiency for rapid PS recharges.
• Monocrystalline cells laminated with ETFE film against dirt and moisture.
• Included protective case turns into a stable kickstand adjustable from 40° to 80°.
• Open-circuit voltage of 48 V and short-circuit current of 11 A cover mid-range PSs and small off-grid systems.
• IP68 water-tightness rating lets it stay outside overnight or through a passing rain shower.
• 2-year warranty backs up the composite construction.
