EcoFlo River 2 Max…. Impressive!!

Great delivery and customer service.
I watched a lot of reviews and made my decision on the River Max 2.
I also ordered the HB21 130 W solar panel, however I have not been able to use it yet due to constant unavailability of the solar cord.
This was disappointing, but appears a lot of other online shops don’t have stock as well.
The solar panel is compact and light weight, it also looks like it’s made from quality materials ( I’m looking forward to using it).
The EcoFlo works very well, and is simple to use!
It’s is lightweight and easy to carry and of quality construction.
I took it camping with me to run my 36 L fridge/ freezer and camp light set up, as well as charging my phone.
It was able to run all of this no problem at all, and for days before needing a top up charge!
Very handy having a long length car charger cord as well, as I have my fridge set up it the back seat area of my ute.

I would definitely recommend the EcoFlo River Max as I was able to charge it very quickly from the wall back up to 100 % in well under an hour.
I can also see myself using this in power outages as well,
The app for your phone is also helpful, very easy to see what your usage and available power left is!
Overall you won’t be disappointed on this quality little unit!

The only thing I would recommend from the manufacturer is that it comes with a solar charger cord so the purchaser does not have to buy that separately (around NZD$70).
Go get it!!
