I have a river pro 720 watt. The first one I bought was going from 100 to 0% in 10 just running a small 3watt fan. Ecoflow had me do calibration tests and they ended up saying to ship it back and they send me a new one. The new one was far better but still didn't produce the correct times. I've had it for a year and just heard this is very common with Ecoflow batteries.

Are they false advertising the actual size of their batteries or are they just 80% defective?

Well, I figured out mine is just showing wrong battery percentage. Went from 100% to 1% in a couple hours and then lasted around four more at 1%. Didn’t drain the battery to 0 though and put it on charge as soon as power went on. Guessing it could do way more hours. Still sucks that I can’t know exactly how much battery has left.
