It pretty much does what it says it does.. I am very happy with this product. I was shocked to see how fast it shipped. The ONLY thing I don't like is that there is no Bluetooth connection. If this is fixed I would give 5 stars

I have the 2000 Delta Max setup as UPS. When I do a firmware update, the unit shuts down and router shuts down. The firmware update stops. Disconnect router from Delta Max before preforming firmware update.

Fantastic. Tons of power, quick and easy to charge and use. This will be great for running our off-grid campsite as well as providing hurricane and emergency preparedness.

I purchased a few of these as backups for my sump pumps. The Delta has the power output and storage capacity to last for days. Plus the ability to monitor and control them remotely is great for peace of mind when we are away.

This is a perfect auxiliary battery power supply, it can power phones, laptops, and more. It has a digital display on the front to let you know how much power that is still available.

Amazing product. I have had two bedrooms without power for the last week and the Delta Max has provided The power to both rooms with no problem at all!!!

The system was everything I expected and more simple to set up than I feared. It charged much faster than I anticipated and I tested the energy draw on some of my appliances. I also appreciated the small amount of space it took to stow.

Im a truck driver i tried a lot of portable power station battery's no one did the job but when I get EcoFlow Delta Max does the job from Microwave ,Coffee maker. Blender and a TV

Haven’t had a power failure yet but i have charged everything I own. Lol. Let the ice storms come, we will be ready. Seriously thinking about getting another one. Great family of products although a bit challenging picking through the website.

We decided that rather than install a gas generator we would opt for a battery backup for our freezer in a power outage. The options and flexibility of the EcoFlow delta max met our requirements
