Is this a reliable company / power bank? EF ECOFLOW Powerstation Delta 2 1024Wh LFP 1800W for 399.99 (original $999.99) on Amazon. I don’t quite NEED this much for my rig, but is this, generally speaking, an insane deal for a power bank? I have an 800W already, but I could rationalize this purchase as it could be a good life-long investment. Let me know what you think!
