So this thread is from a while ago, and seem EF is shipping product now. I've been thinking of getting one of these units to run a coffee maker or hair dryer in the RV. We have a whole DC system, lifepo pack and 600W inverter, solar, chargers, and all that jazz. A portable would offer quick high-power without the genset, and for in the house for a blackout. So I'm looking at the River Pro or the Delta Mini.
Any comments? Recommendations? What about compared to Bluetti or Jackery?
I take it Will had some problems with one a couple of years ago when they came out.
Oh, and Bluetti EB700 has lifepo batteries, these others seem to be lithium ion. Any comments pro or con? The EB700 also looks very attractive.
