I just purchased Ecoflow Delta 2 recently. I’m very impressed how easy to use and operate and charge quickly for 1 hour or less. The only problem I have is using Wi-Fi connection. The Bluetooth was easy to connect. I have my tv, and Wi-Fi router, stand up light , portable radio, cell phone chargers in case of power outages. I’m glad this was my choice of back up power , instead of gas generator. It’s portable and I can take it anywhere with me. I’m learning slowly, but have not tried yet on solar panels. I’ve been testing my Delta 2 power station turning off power at home to see how long it will power my equipment without the electricity for several hours. I got my information from YouTube watching ecoflow videos before purchasing this product. It’s worth the price!
I bought this to replace a smaller unit that could not backup my fridges or freezers. It is much lighter and more functional than the Delta 1300 I purchased a few years ago. I prefer the LiFePO battery and it's associated longer life. It does not have as much battery capacity as the Delta 1300, but the inverter appears to be the same. I like the ability to set the charge limit to 70% while using it as a UPS. The UPS functions very quickly and has been running a freezer and some other appliances without problem. It was a little slow to update the firmware when I got it, but it seems to be doing fine now. I don't like that one must connect the device via WiFi to get updates. It wants access to my home network and that is forbidden to the Chinese (and other) companies.
Overall, I like it and it works so far as a UPS for my freezers and fridges.
So far I am loving this sogen. Runs my microwave, and air fryer with no problems. Vacuum cleaner with full power. Tv,router, Roku, washing machine, all without a problem. Tomorrow will hookup pv 400 watts and see how that goes, but so far I am pleased.
Honestly, do your research and follow your gut… there are a lot of good products out there, but this unit had just what we were looking for. And, from a company that stands behind it’s products.
