EcoFlow DELTA 3 Max Portable Power Station vs EcoFlow DELTA 3 Ultra Portable Power Station

Both are LFP home-backup stations with 10ms UPS switching, so the choice comes down to capacity versus portability. The DELTA 3 Max is the lighter unit at 20.3 kg and recharges faster from the wall, reaching 80% in about 68 minutes. The DELTA 3 Ultra carries 50% more capacity and higher output, so it runs bigger loads and lasts longer in an outage. Owners rate the Ultra well, and both share the same battery chemistry and build approach.

• Choose the DELTA 3 Max if you want a 2kWh station you can still lift and move between rooms, and you value the faster wall recharge.
• Choose the DELTA 3 Ultra if you need to run large appliances or ride out multi-day outages and can accept the extra bulk.
