Thanks to EcoFlow, it was a successful winter skating on the nearby frozen pond. With my River 3 and Delta 2 powering the water pump, I was able to keep the ice surface nice and smooth. Bringing out the EcoFlow multi functional camping light allowed for working and playing long after sunset. Now with the ice melted and the weather warming up, I hope to finish a solar powered tool shed - until in 9 months, get back out on that ice again with EcoFlow!
