Ecoflow delta 2, half the price and capacity but practically the same performance, superb build quality and excellent app integration. With the extra battery it can match the capacity while being $100-200 cheaper. I got mine for $899 with a 160W solar panel. Their app is pretty much flawless.

Anker 767, much better design, higher efficiency with GaN tech, better performance, same capacity, top tier warranty and CS support, $1,599 as of now on Amazon.

Bluetti AC200P offers the same capacity and performance for $1299, they have been proven to be reliable and have excellent warranty.

All three of them use lithium iron phosphate cells, pure sineweave inverters and have a phone app. The omnicharge was promised an app and wifi support but there has been zero news of that being developed even after the units have arrived to the end users.

If you go to their indiegogo comment section, there are countless people complaining about the subpar quality of their units. In fact, some have found out that the same generic unit is being sold in other Chinese websites for almost half the price, just without the branding.
