Not for Van
This is a great buy if you’re needing a 120v bay backup. Now, if you’re trying to use the 12v to power your van…nope. It will not power a Webasto Evo 40 due to the initial amperage draw. I tried 6 way’s to Sunday and had to go with the Goal Zero 1500x, works great now.

Less than hoped for performance
Just tested new Delta Max. After fully charging the battery I tested it on a load that normally draws about 1 KWH of energy per day. The battery was able to supply the load for about 18 hours before the AC output was turned off. This is supposed to be a 2KWH battery, but no battery system is 100% efficient so I was hoping to get at least 24 hours. Just 18 hours is less than I was hoping for. In its final configuration the battery will be connected to a solar panel array, so it will probably be able to carry the load. We will see...

FIrst use review

My new Delta Max 2000 is installed in my outside shed which is within 10 feet of the side garage door. I installed a 4 pole L14-20R receptacle on the outside of the wooden shed that will be used for the Derlta Max AC output. A transfer switch and cable are in the garage. Also added to the shed was a NEMA 5-20 plug for the Delta Max AC input charge line. Next will be 400 watt solar panels on the roof. Today I powered both my washing machine AND the gas dryer doing two loads. The Delta Max worked fine and when the wash was done it had only dropped down to 70%. Amazing, quiet power source. The spare battery just arrived so that's going in right away. The phone app is a nice touch to keep an eye on loading and charge rate.

Does what I wanted it to do.

This item was purchased to compliment my Honda 2200 generator so that if there is a power outage I can run the generator in the daytime but to keep things quiet I can run my ECO-Flow at nite. I also use it to charge our electric bicycles and battery powered lawnmowers to that these items are "OFF the GRID."

Powers up fast!

Whith the Delta Max we can power a week long camping trip. We generally run a small fan in tents, charge cell phones x 5, and keep some LED lights going and never get close to killing this battery. We have not tried any winter camping so I can't say how it will handle a heater. If I had enough money I would have went with the one of the smlwr river systems for camping and bought the Delta Pro for my home, but we settled on the Dleta Max so it could be used for both. It over exceeds expectations while camping and does a pretty good job at home during power outages. I have not ran a full test, but I have no doubt with the 220 W portable solar panel and a small gas generator I will never run out of power. The Delta will charge to 80% in less than an hour using an outlet in the house and will charge in about 2 hours using my small genarator. We'll worth the investment.

Delta Max 2000 - Emergency Backup Power!

I purchased my Delta Max 2000 with the Wave bundle. I will be using it as my backup power during power outages and other emergencies. So far, I've tested it by powering two fans all night. By morning, the Delta Max 2000 still had over 60% power left! I tested all ports to make sure they worked. I also recently purchased the EcoFlow 160 solar panel to charge my Delta Max 2000. I was able to achieve 130 watts input, which is pretty good! I'm planning to expand the power by adding an extra battery soon. I am confident that I will be able to power my needs during a power outage or other emergencies. I love the fast-charging feature!

Quality product!

I purchased the Delta Max 2000, and 2 of the 220w bifacial solar panels for emergency backup power when the electricity goes out. It will keep the refrigerator and deep freezer running so food doesn’t spoil. I charged it with with the home a/c outlet and have not used the solar panels yet. I plugged in the refrigerator and deep freezer and it has plenty of power to keep them running until it can be recharged with the solar panels. I believe this will be perfect though I haven’t tested the solar panels.

Back up generator

I’m very satisfied of my Delta max 1600. I used it for Back up Ups to my Security alarm and internet modem and router in case of emergency. I’ve been getting a lot of blackout around my area and was able to continue power some of my electrical equipments. No problems yet on the ecoflow Delta max 1600. Thank you so much!

Generating peace of mind

I purchased the Delta Max, extra battery and a couple of solar panels for blackout situations. This is an increasing occurrence where I live and I want to be prepared. Having my generator and panels gives me much more peace of mind should the situation get dark, literally and figuratively.

Great product

I’ve been using the EcoFlow Delta Max for almost a month and use it daily. It’s a great product. I currently use it to power a portable AC. I got the bundle with the wave and patiently waiting for its arrival. I will be getting some of the accessories like the extra battery, solar panels and generator. The reason I went with the Delta max over the Pro is the weight. With the Pro weighing close to 100 pounds, the Max is easier to carry. I do wish it had wheels like the pro but it wasn’t a deal breaker. Overall I’m happy with the performance of this product.
