EF ECOFLOW DELTA Max (1600) Portable Power Station, 1612Wh Expandable Capacity with 6 x 2000W (5000W Surge) AC Outlets, Solar Generator for Home Backup, Emergency, Outdoor Camping or RV Travel

Charges well on its power cord to the wall outlet. And you can turn it all the way off so there is not parasitic drane on the battery.Good for running a frig of or it for a small power outage.I wish it used the new safer LFP Type battaries like a delta pro ultra.

I bought this power source after my neighborhood was hit by Hurricane Helene. We were without electricity for 12 days. The Ecoflow kept my phone and headlamp charged, but more importantly, it allowed me to run the window AC for a few hours at night so we could sleep. It’s heavy, but it charges quickly when plugged into a wall. I am very happy with it.

This portable power station is amazing! We can now continue using the Internet and watch TV even when we have no electricity. We can also keep our refrigerator running at the same time, charge our cell phones and tablets, and plug in other devices that require electricity.It's very energy-efficient and easy to move around since we placed it on a small board with wheels. I highly recommend it.

Everything works well except I have had difficulty shutting the unit down a couple times.***Updated on 7/11/2022.*** Customer service contacted me within 24 hours of my post on Amazon. The problem was me not the Delta Max was holding the on/off button a little too long. I have had the Delta Max now for almost a month. I'm extremely pleased with the operation of it and how easy it is to use. The app on my phone works well and I can check on the device even when I'm out of town.

First of all I ordered this unit by mistake. Since the seller doesn't accept returns AT ALL, let me review the product and the reason that I never wanted this unit to begin with.This unit has a 500 cycle life and low total kWh. If you hook this up to solar and use it on a routine basis it will not have a very long life. Depending on the draw it could be less than 1 year. The total cost of ownership is not worth it. Look for a better and yes, more expensive, alternative using a LifePo4 batteries. If you hooked up a very low power heater while camping and left it on all day this unit would only last for 60 days.Do your homework and don't order the wrong one by mistake.Update: I actually had an issue with the unit where it wouldn't charge via solar and output power at the same time. For some reason, although production was 2x the consumption the battery wouldn't charge. I was able to return the unit as defective, so I guess I got lucky.

ProsIts pretty beefy for most small stuff at 1600 watt hours.App control is nice which can display all information and control chargingHas ability to reduce charge rate to prevent tripping breakersCan be charged by solar and car 12v, note that both of those are much slower charging.Almost completely silent and only makes noise when chargingThe main reason I bought it, can be expanded to 5600 watt hours. That's quite a bit.Likely great for an RV, haven't tested that yet but I hope to soon.ConsOnce off grid, application control is out. Went camping and couldn't power it on.Left it on for a day and completely drained the battery with no loadVery heavy, unit by its self is about 40 lbsExpensive and expansions are more expensive. Unit plus two expansions is over $5k.Unknowns (to me at least)Not sure if they support increasing the solar panel input to increase the charge. I suspect they might support at least one solar input for each expansion.

Didn’t like the fact that It won’t connect to my Orbi network which has 2.4 GH

If it must be signed for, tell me!!! I spent hours on the phone and waited at home for hours. The product is great, delivery horrible.
