Ecoflow river pro (might have received a faulty unit)

I have a major concern. I purchased the Eco flow river pro to run my TV During loadshedding.

The battery only has to supply around 170Watts of power during loadshedding. 1x TV drawing about 105Watts , 1x surround sound , 1x light is connected to the battery. All these only pull roughly 170 watts. The device is supposed to supply 720Wh. This means it should be able to supply power for 4.2 hours. But the battery is not even able to supply this for 3 hours?

I sent them proof on photos of the power usage and hours left Loadshedding started 16:00. We only got home around 17:00 yesterday , so for a whole hour the battery wasn’t even being used.

17:37 it shows 3 hours and 13 minutes left which means I should have power until 20:50. (This is with everything on which is connected to the battery. 18:36 it shows 1Hour and 34 Minutes left 19:50 it shows 6 minutes left – and I had to switch off my TV.

What happened to power until 20:50? You are welcome to pull a log, I did not use more than lets say 175Watts at a time yesterday.

I was planning on buying the Delta range for my computers, but not if this is happening.

This product isn’t doing what I believe it should, or maybe I received a faulty unit. I would like Ecoflow to replace this unit with a proper working one. Otherwise I will have no other choice than to complain about this product on social media.
