Which one is right for you?
For a pure backup solution for Wi-Fi + fridge during a power cut → Bluetti AC180 (UPS under 20 ms is great for NAS/router, 1,152 Wh lasts 6 to 8 hours). Camping + solar + fast charging + up to 2,400 W continuous power → EcoFlow Delta 2 Max. Per Wh the Bluetti is more economical; in absolute terms the extra 1,000 Wh is worth the extra investment as soon as you want to run an air conditioner or kettle.
