EF EcoFlow DELTA Pro Smart Extra Battery Portable Power Station 3600Wh Capacity,Solar Generator for Outdoor Camping,Home Backup,Emergency,RV,off-Grid

I love this item. I ordered it to power my home during outages. I live outside city limits and we often go without power for days during winter. I charged it, plugged in several small 200 watt heaters, a light and a fan and it did an awesome job.

Really pleased with the two extra batteries I bought for the two Ecoflow Delta Pros I bought. It's best to learn a little about how these batteries work so they work most efficiently and last the longest. Best way to do that is by joining one the Facebook Delta Group. Lots of knowledgeable and helpful members. The battery is heavy like the Delta Pro it supports because it has the same capacity, 3.6K Watt hours. The cable that attaches the battery to the Delta Pro is short so consider that when you are planning where to put it. The good thing is that two batteries can be attached to the Delta Pro, giving a total of 10.8K Watt hours.

We live in Florida and can lose power for 3 to 5 days during hurricanes. We have a gas generator but can't run that during the storm so purchased this EcoFlow DELTA Pro so we don't lose all our food which has happened in the past. Tested it out with our side-by-side refrigerator/freezer and overjoyed that kept it running for 25 hours. We plan to use the gas generator during the day and the EcoFlow DELTA Pro during the storm and overnight. Very happy with the performance.

Very happy with the extra battery. Thanks to the extra battery, when the power goes out in our neighborhood, I wont have to worry about a thing. I can just swap to my ecoflow setup. With the extra battery and solar panel, everything recharges really fast in the day. Super excited to have the power go out again, as odd as it sounds!! Any excuse to use my Ecoflow!!

I purchased the DELTA Pro Smart Extra Battery a few weeks ago, hooked it up to the existing DELTA Pro, charged it up and waited. I did not have to wait for long. A few nights ago it was 2 degrees out when the power died up and down the street. I unplugged my furnace from line power, plugged in the Delta Pro pair, and went back to bed toasty-warm. What a great relief to know that Ecoflow has my back when the power dies again.

It's good. But very expensive. Cannot run entire house on one but even a 10 circuit manual transfer switch that can power a lot of things will only stay powered for 53 min if using the entire 3600 KWH OF POWER! So need to purchase yet another unit extra battery to power things longer with 7200KWH CAPABILITY! That's my disappointment with it. But it's better than having nothing. Just can't afford to keep purchasing more to power house which in a long power outage will work. Need to come up w a quicker recharge not by electricity. I have the 400W solar panel as well. Can't use at night of course and not as quick as the electric charge.

You get the basic chords no extensions and if you want to expand just be aware of how expensive the batteries are. Very good,BUT Just be aware of how heavy the system is and if you want solar panels you'll have to buy extra wiring if you put more than one panel on it in parallel or daisy chain and have some kind of extension wires

Coupled this with my Delta pro main unit. All is working well, but really nee more flexibility on the connection cables. The basic ones are just long enough if the units are directly side by side. This limits where one can place the equipment (eg stacking or wanting to leave more space between units in poorly ventilated ares to improve air flow.

I purchased the EcoFlow pro series with 2 extra batteries. Also purchased the 4000 watt Smart generator. For my off grid cottage. They are supposed to work together, especially during the short day winter weather. Big problem, I can't charge my whole system at the same time. There are only 2 ports to the Pro, so I have to sacrifice 1 battery when I charge them. PLEASE make an adapter so I can use my system in the way it was intended.

I accidentally ordered the extra battery instead of the main unit on a Friday night and tried to cancel Saturday, what an ordeal that was! I tried to stop it from being shipped but right away they marked it already shipped so I couldn't do anything, multiple emails and more, even calling them didn't stop it and it was on it's way WEDS... I wound up refusing delivery and it was returned by FedEx- so it never touched my porch. They claimed they refunded me but 2-3 weeks went by and no refund; "Dear Customer, Thank you for letting us know. The platform has already processed your refund to your original payment method. It may take a few days for the amount to appear in your account. If you have any questions or need further assistance, please feel free to contact us." It took filling out a CC dispute and a solid MONTH before I finally got my money refunded by Ecoflow and it was only after filing a dispute with my CC.
