For overnight use, recommend extra battery

We use is to run are boats power needs instead of running the on-board genset. The unit will run both the refrigerators and hot water heater and other small power accessories all day and the solar panel keeps the unit at around 90%. The app sux however I don't need to use. I'm getting another solar panel for more charge power because the unit will drop to 20% over night and need to run genset to get power back in for the panels to bring power up quickly.

This is one of the most important investments you should own.

I love camping! The EcoFlow Makes your life easier. Simple device that brings your home outdoors and to wherever you choose to be. If you want a plug and play device, this is it. I own 2 of these, purchased one for my parents because they were concerned about their freezer during the last power outage. The other I use every week when I head to the hills and camp. If you are on the fence about whether you need a power source backup, just turn on the news and you'll receive your answers. For me.. This device will make any bad situation, just better.

Top shelf gen

We recommend. We did our research and decided for this generator. We have a condo and this works perfectly. No noisy gas running generator. We put the solar panels in our patio. We are ready for the apocalypse now 😂.

Abel Prasad
Extremely effective

This offers multiple ways to charge up the generator. If there isn't enough sun it can be plugged in to wall outlet or charged with a vehicle.

Love Eco Flo

So easy to use. Is powering my shed and an AC. And I’m a DYI - not a solar guru. I own the pro, the max and the delta. Love them all.
