Excellent device – I bought the EcoFlow River 3 Plus and 45W solar panels. The purchase went smoothly, and the pickup was exactly as promised. I also received a prompt reply to my email inquiry and even got a call from them letting me know the device was already waiting for me at the warehouse. The pickup was easy, and they even helped me install the correct app. The price was the best I’ve seen in New Zealand.

Back Country

Bought this unit to recharge batteries in a back country hut. It does so much more. Was sceptical about sola panel out put but got it up to 58w which I would say is a win.
Good buy
