Ecoflow Delta 3 Plus
I've bought the Ecoflow Delta 3 Plus to power a Wave 3 Air Conditioner. After a couple of days is showed a mistake and stopped charging from the grid. I've contacted customer service and they offered to fix the problem, sending me a delivery ticket. My only complaint is that replying to my emails took too much time. Otherwise, the repair and return were fast and resolved the problem. Now I use the Delta for a lot of stuff like powering my camper van, using power tools and charging phones and laptops when off grid. It works pretty fine.
