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.

The media could not be loaded. Ecoflow Delta Mini is my second Ecoflow power station. My first one is Ecoflow River Pro that I got from Costco during sales event. It runs great when I take it out for day trip, but I needed a more powerful battery station that I can fully run full-size fridge and other electronics when power is out. This is why I bought the Delta Mini which has a 1400W AC output that can handle most of the major electronics in the house.Out the box I decided to run a quick calibration of the power station because I could not get a 100% full charge reading from the read-out panel after battery stopped charging. I charged up the power station and then drained the battery down to 0% and charge it back up. That did the trick of recalibrating the power station and it showed 100% charge at the end. Then I paired up Delta mini with the app and ran an update on the firmware. Everything went well without any issue. I ran a test with Whirlpool full size refrigerator. It was pulling 150~600W effortlessly. I figured I can get about 8-12 hours from a fully charged Delta mini since fridge does not run all the time. Next, I used the power station to run a rice cooker. The rice cooker was pulling 8-900W and drained the battery really fast, this also caused the cooling fan to kick in high gear to dissipate the heat that was creating. I decided to plug in the AC cable to start charging the battery station before it drained out. Interestingly, I set the AC wall input limit at 200W from the phone app, but the station decided to charge at 1100-1200W to be ahead of what rice cooker is pulling. At the end, I have more power than I first started.Ecoflow Delta mini and River Pro power station is now taking turn to be used during the weekend when the family goes out. The power station is used to power my 30L portable fridge and other small electronics. The power stations will be down about 20% after running the portable fridge at 3C degrees for 8-9 hours by using the DC port. After several weeks of running the battery station, I am very impressed with Delta mini, and my friends are showing interests to gat one too. At the moment Amazon has a $50 coupon for Delta Mini, which will bring the final price cheaper than when I made the purchase. 5-star for Ecoflow Delta Mini.

I love the Home Panel 2 & Deltra Pro Ultra design and the fact that battery backup is easily expandable, just add extra batteries into Delta Pro Ultra stack. The Home Panel 2 is much better looking and functional as compared to other smart panel solutions in the market. Best part is that you can any brand breakers and the panel can smartly control them. The trolley for Delta Pro Ultra has wheels to easily move it but has an option for fixed rubber pads too. The battery pack can easily be unplugged from home panel and can be used for parties in your backyard, carried in car for camping purpose etc. The casing of the batteries looks sleek but is also built pretty solid and durable. Moreover, the this Home battery backup solution qualifies for federal tax rebate of 30% too because each battery capacity is 3.6 kWh which is well above the 3 kWh qualification requirement.

Plugged into a SHP and working great. Will update after a year or so.
