✅ Specs verified against the manufacturer's official listing — source · Last checked
Our verdict
The value leader in the 2kWh class. Same 4800W surge as the DELTA 2 Max at $500 less, with 1000 more cycles.
Best for: Home backup buyers who want compressor-starting surge without paying flagship prices.
What we like
- 4800W surge at $1099 — surge headroom usually reserved for units costing half again as much
- 4000 cycles vs the DELTA 2 Max's 3000
- 82-minute recharge
Where it falls short
- 55 lb is a two-hand lift
- Only marginally lighter than heavier rivals
