At a Glance
This comparison targets buyers choosing between two 1800W LFP portable power stations with identical surge ratings of 2700W and the same 500W solar input ceiling. The AC180 edges ahead with a larger 1152 Wh battery (12.5% more capacity than the DELTA 2's 1024 Wh) and a longer cycle life of 3,500 versus 3,000 cycles, which translates to years of additional service for regular users.
It also includes UPS functionality with a 20ms switchover, a genuine advantage for home backup scenarios like keeping a modem or mini fridge alive during outages. The tradeoff is weight and flexibility: the DELTA 2 is nearly 10 pounds lighter at 26.5 lbs and supports battery expansion, making it the better platform if you anticipate needing more capacity down the road or frequently transport the unit.

The Bottom Line
Pick the AC180 if longevity and built-in UPS matter most; its higher capacity and 3,500-cycle rating suit stationary home backup and extended off-grid use. Go with the DELTA 2 if portability and future expandability are priorities, since its 26.5 lb frame is easier to move and extra batteries can scale total storage well beyond 1024 Wh. Overall, the AC180 takes the win on durability and backup readiness, but the gap is narrow enough that your specific use case should drive the decision.
