Features
- Charge Anywhere. Replace your outdoor generator with clean, renewable energy. A single 125W solar panel has a high conversion efficiency of up to 25%, and 4x125W solar panels can fill DELTA Pro Ultra in 15.4 hours, 8x125W in 7.7 hours, 12x125W in 5.1 hours. Suitable for emergency power outages at home or during camping.
- One Powers All. The unit of DELTA Pro Ultra whole house generator includes an inverter and a battery. One inverter supports 120V & 240V and has an exceptional 7200W output, allowing you to run almost any heavy household appliance, even a 3-ton central air conditioner. Triple the inverters for an incredible 21.6kW AC output, allowing you to live life to the fullest even during an outage. The electric generator achieves a total 7200W output even during charging.
- Strong Power Security. Scalable from one battery of 6144Wh, two days of essential power, all the way to 15, it multiplies the energy to a gigantic 90kWh. For a standard North American household, that's over 30 days of essential power secured.
- Multi Ways to Charge. One battery of 6144Wh can be fully recharged in 2 hours. Faster than any other 6kWh solar generator. Users can choose among electric vehicle piles, solar, wall outlets or outdoor generators for charging.
- Light and Durable. The 400W Solar Panel is foldable and comes with an adjustable carry case. Weighing in at only 16kg (35.3lbs), it can be easily packed up and carried with you, no matter where you go. It also comes with a IP68 Waterproof rating, meaning it is dust and water tight.
- *Kindly remind that the inverter, battery and solar panel will be shipped in separate packages.

My experience with the purchase of the Ecoflow Delta Mini started out being frustrating, but ultimately the unit met my expectations fully. My desire for a portable power station was for a backup power solution in the event of emergencies. I wanted a unit that would be able to recharge our devices as well as small appliances for a substantial period without access to home electrical power. Another requirement was the ability to recharge the battery unit from a solar panel in case the power did not come back in a reasonable period of time. After some research, I settled on the Ecoflow brand and the Delta Mini as the model that could suit my basic needs while remaining within my budget. I initially purchased the Ecoflow Delta Mini listed at $799 with a $50 discount coupon upon checkout. I also purchased an Ecoflow 160 watt solar panel to accompany the battery unit for $349. I was pleased to receive both items within a few days of the order. Unfortunately, the Delta Mini I received did not work properly. The unit would charge up when plugged in and I could charge devices from it, but the power button (on/off) did not work. After shutting down from inactivity, the unit would only become active again if plugged back into the wall. Not good if you need to use the device but have no access to a working power plug. I called Ecoflow and after a short evaluation by the operator and an email, they agreed that the unit was defective and arranged for a shipping label for return and eventually replacement. Unfortunately, the process to receive a new unit would take several weeks. To avoid such a long wait, I sent the defective unit back and ordered a second unit from Amazon. The new unit arrived a couple of days later. Not long after, my defective unit got back to the factory and I was issued a full refund. Minor frustration, but the company made it right. As for the Ecoflow Delta Mini, it works as expected and very well at that. I tested it with the devices that I planned to power it with and found that it charged up multiple devices via the USB outlets at the expected rates. Even fast charging those phones via the one USB that has that capability. The unit also powered small appliances (albeit with significant drain of the battery). I tested a 1500 watt electric kettle with 1.7 liters of water, and was able to get a full boil in 6 minutes with about 16-18% batter drain at each attempt. The same test with 1.7 liters of water on a single burner 1200 watt hot plate took 13 minutes to a full boil and drained 36% of the battery. A test of keeping a 7 cu. foot freezer alive overnight (12 hours) gave me a 60% drain of the battery. All in all, interesting results. It meets my needs, but be aware that if you hope to power more appliances for a longer period of time you will need one of the bigger and more expensive units. As for recharging, the Delta Mini charged up very quickly from the wall plug. It only takes an hour or so to top up from the 50-60% area to full. When it’s really low (below 30%) you might need up to two hours to get a full charge. I was impressed with the solar panel. It was listed at 160 watts, and with full sunlight it gave exactly that. As the clouds passed by it dipped a bit (103, 137, etc.) but as long as the sun was strong it was plugging right along. However whenever the clouds blocked the sun, the output dropped all the way down. Sometimes in the 24-77 watt range, but often at zero. Keep that in mind, as the weather of the day will affect how much re-charge you will get. My test day had strong sun, but with periods that the clouds passed over and blocked it completely. All told, in that session it took me 1 hour to gain a 10% charge on the battery. If you are going to rely on the sun to get your battery from 0 to 100, expect it to take all day if it gets there at all. Perhaps a second (expensive) panel might make that more realistic. Overall, I am very pleased with the purchase as well as the response by customer service to my issues.

I went this route vs a propane or gas generator. It allows me to do so much more than traditional generators. The smart panel allows you to control your circuits from your phone or the Tablet that came with it.

I think this battery generator is the best on the market. I keep it changed and when the power goes out, this unit will power my 7000 BTU portable AC, my refrigerator, and some lights for many hours. It has one of the best batteries in it. Not low grade batteries.

Absolutely Amazing product! However Ecoflow ships with Fed Ex and requires signatures .. I have ordered 3 times totaling 4 deliveries .. The first delivery that I took the day off for failed to deliver .. FedEx said they attempted to deliver it however I was on the porch all day and my cameras show proof there was never a FedEx truck on my street that day.. That package was not delivered for 2 additional days that I needed to stay home for due to "Signature required" the Second delivery was once again "Signature required" My delivery window was between 10 am and 4 pm So I took the day off.. however at 12:01 am the next morning FedEx once again showed a failed delivery .. their support line insisted a driver attempted to deliver it .. once again cameras proved otherwise.. That brings us to the third and final delivery ... The package was set to deliver yesterday between 11 and 4 .. so I took the day off , at 2 pm I received a notification that my package was being held " At my request" .. I called Fed Ex again and was informed the package was held at my request with the reasoning that the package was not in Wichita ( My City ) to be delivered .. after an hour on the phone they agreed to have the package left at a Local FedEx office store for pick up ... I went there to get it this morning and was told they did not have it and would not get it due to the weight and I was given the number to the local FedEx ground distribution center .. I called they told me they had the package and that I could come pick it up from them at 10 am .... I drive 15 miles to get the package wait 30 minutes with my car actually inside a FedEx distribution center only to be told ... "They do not have my package and it must be on the truck" ...... So now I have lost a 4th day of pay due to Ecoflow's shipping decisions .... this whole process has been absurd and very draining ...... EcoFlow's product delivers everything they claim .... if you can manage to get what you paid for. .... I would not suggest anyone order from Ecoflow unless you can devote a solid week to be at home for delivery or somehow arrange your own shipping. Ecoflow's shipping choices will lead me to likely never purchase from them again.
