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.

Had a large gas-guzzling Honda 7000/12000-watt generator that didn't have an electric start and was too loud to run in my current housing development. Not to mention it was a bear to set up and startup. Chronic back pain prohibits and limits my ability to set up and run this outdated and inefficient solution. So, I did some homework and found the ECOflow product line. I already owned the ECOFlow delta and using it as a temporary solution to keep my fridge, microwave and a few lights going during a power outage. Then ECOflow introduced the Delta Max and Delta Pro. I decided to purchase the Delta Max and 2ea additional smart batteries. My reason for this was product weight, product foot print and cost. The Delta Max solution was easy for me to move/transport and setup. At around 50 lbs or less for each module, I can easily move and setup this solar powered generator solution without wrenching my back. I now have a quiet, efficient Backup power during those unexpected power outages. With just the Delta Max I had around 4 hours of battery backup run-time. I am talking about powering every thing in my home except those devices that require 2-phase power. With 2 additional smart batteries I now expanded my capacity to 6kWh and have roughly 12 hours of runtime. I purchased 4ea Ecoflow 110 watt solar panels and plan to build a portable frame to put them in my front yard to charge up the batteries using solar power. In addition, I purchased a Generac 7117 Gp2200I W 50St Inverter generator that weights around 47 Lbs. It’s light and easy to move around. It’s very quiet and extremely gas efficient. I use it to charge up the solar generator batteries when there is not enough sun light. I live in the PNW so it’s not the sunniest place in the USA especially during the winter months. The Delta Max has a smartphone application that connects via bluetooth that I use to determine my power consumption, run-time remaining and many other aspects for controlling the solar generator environment, including doing firmware updates as required. One neat feature of the application is that I can control how much power the solar generators demands of the gas generator while recharging the batteries. The solar generator can demand as much as 1800 watts of power during a charge cycle. I like to limit this to 1300 watts. This lowers gas consumption and noise on the gas generator during a charge cycle. The Delta Max has the ability to provide 3400W of power with ease using X-Boost technology. This allows the concurrent use of power hungry device like microwave, fridge, heater, dish washer. ect… You can use the application to stay at or below the 3400W limitations. For me it was easly achieved. I even keep my bidets powered during power outages. I just put them in low power consumption mode. Do your homework and be smart. Determine your wattage requirements for all of the items you want to power up during a power outage and then determine the worst case aggregate power requirements and you’ll be able to determine what devices can run concurrently using the Delta Max during a prolonged power outage. Use this link to purchase a cable to connect the Delta max to your existing Generator power transfer switch: https://www.amazon.com/gp/product/B08H85RQ6X/ref=ppx_yo_dt_b_asin_title_o05_s00?ie=UTF8&psc=1 I really like and am impressed with the products that ECOflow manufacture. I am very tech savvy and a DYI guy so it wasn’t hard for me to research and integrate this product for a reliable and safe electrical backup solution. I haven’t had any issues using this solution during several outages since installing it. I haven’t had the need to call their tech support so I can’t comment on there abilities to support the product. I did my homework thought and it seems that they have their stuff together for good customer service and support.
