Pros & Cons
What We Like
- 2,048Wh LiFePO4 capacity with expandability to 6kWh
- 2,400W output with X-Boost up to 3,400W for demanding appliances
- Full charge in about 1 hour via AC — among the fastest in class
- Smart app with real-time monitoring, scheduling, and firmware updates
- 6 AC outlets plus comprehensive USB-C/USB-A port array
Watch Out For
- 50 lbs — manageable but not truly portable for one person
- 3,000 cycle life is lower than some LiFePO4 competitors
- X-Boost mode reduces efficiency on high-draw appliances
- Being superseded by DELTA 3 series — may see reduced support
