Features
- 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 have ordered several different power stations. This Mini from Ecoflow is one of the best. What I love is the display, which tells me exactly what is flowing in, out, the current power draw, and how long I can expect the battery to last. It's very easy to use, has multiple ports: USB-C 100W, two USB-A standard 2.4A ports, and a USB fast charging port on the front, and on the back, 5 120V AC ports (pure syne-wave), two 12V 3A mini-ports and a standard 12V port (126W max), You can set the charging speed to slow or fast, there's an 11-75V DC 10A 300W charging port for solar or car charging, a 100-120V 50-60 Hz AC charging port. And the top is a wireless charger for phones! The battery is NCM Li-ion, 882 Wh, 1688W output. It has two nice carrying handles, and weights only 23.5 lbs. We use it to power our refrigerator while camping, as well as charging phones, watches, and other items, and as short-term power back-up at home when our power goes out. It has WiFi, so it can be controlled from a phone. The only slight thing I don't like is that the vents are on the sides, so packed in a car with lots of stuff, you need to make sure the vents are free. A newer model has the vents by the handles, which is better.

The delta pro ultra is awesome and the solar panels are powerful. I have this powering my shed. I mounted my panels to the roof with some brackets I printed (even though these are really meant to be setup on the ground and portable. It was a prime day buy and it's where I needed them :p) I have it charging my ego mower with 6 10ah batteries and it does great. I also have it powering a sparkfun mosaic X5 for my personal RTK corrections source. I've ran my table saw and chop saw off of it without any issues, just like plugging into a regular wall outlet. I'm gearing up to install some outlets and hooking them up through the main input output port. I wish I had more batteries but honestly the single unit with one battery has done everything I need for in there. It's definitely a chunk of money but it's quality and customer service you are paying for. I had one panel cracked out of the eight and they sent a replacement without any hassle at. I greatly appreciate it EcoFlow. I'd give this more stars if I could. Just a heads up, it's bigger than it looks on the web and it's heavy. Don't do what I did and move it in to position by yourself. Next order: a pallet of Aleve and Tylenol.
