At a Glance
This comparison targets buyers weighing raw power and device coverage against portability and long-term battery life. The Yeti 1500X delivers 2000W of running power and 1516 Wh of capacity, nearly double the AC70's 1000W and 768 Wh. That gap shows up in real-world testing: the Yeti powered 43 of 53 devices, while the AC70 handled only 24.
Surge capacity tells a similar story, with the Yeti reaching 3500W versus 2000W for the AC70. Where the Bluetti unit fights back is longevity and weight. Its LFP battery is rated for 3000 cycles, six times the Yeti's 500-cycle NMC pack, and it weighs just 22.5 lbs compared to 45.6 lbs.
Solar recharge is also faster on the AC70 at roughly 2.7 hours versus 5.4 hours for the Yeti. The tradeoff is straightforward: more power now or more lifespan per pound.
