At a Glance
This comparison targets buyers choosing between two 1800W portable power stations with similar device coverage and capacity. The DELTA (Gen 1) edges ahead on raw compatibility, powering 40 of 53 tested devices versus 39 for the AC180.
It also delivers a higher 3300W surge, giving it a better chance of starting demanding motors and compressors, and it does so at a lighter 30.9 lbs compared to 36.2 lbs for the Bluetti unit. Where the AC180 fights back is longevity and resilience: its LFP battery is rated for 3,500 cycles, more than four times the DELTA's 800-cycle NMC pack.
The AC180 also includes UPS functionality with a 20ms switchover, a feature the DELTA lacks entirely. Buyers prioritizing long-term value and home backup will weigh that tradeoff heavily against the DELTA's portability and surge advantage.

The Bottom Line
Choose the AC180 if you need a unit that doubles as a home UPS and you plan to cycle the battery daily for years, since its 3,500-cycle LFP chemistry will far outlast the competition. Go with the DELTA (Gen 1) if lighter weight, stronger surge capacity, and slightly broader device coverage matter more for camping, job sites, or occasional emergency use. Overall, the DELTA (Gen 1) earns the narrow win with a 75.5 to 73.5 score, driven by its superior portability and one extra compatible device in testing.
