Capacity
AC200MAX: +1,024 Wh (+100.0%).
This comparison targets buyers weighing raw capacity and device coverage against portability and faster solar turnaround. The AC200MAX delivers 2048 Wh of LFP battery capacity, roughly double the DELTA 2's 1024 Wh, and its 2200W running output (4800W surge) powered 45 of 53 tested devices compared to 39 for the DELTA 2.
That wider compatibility gap matters for home backup scenarios involving high-draw appliances. On the solar side, the AC200MAX accepts up to 900W of panel input versus 500W for the DELTA 2, but the smaller EcoFlow unit still charges faster at 3.7 hours versus 7.3 hours thanks to its lower overall capacity.
The tradeoff is weight: the AC200MAX tips the scales at 61.9 lbs, more than twice the DELTA 2's 27 lbs, making the EcoFlow unit far easier to move between campsites or rooms.
